/***********************************************************************
MODULE NOTES:
1. There are two philosophies to building string classes:
A. Hide the underlying buffer & offer API's allow indirect iteration
B. Reveal underlying buffer, risk corruption, but gain performance
We chose the option B for performance reasons.
2 Our internal buffer always holds capacity+1 bytes.
The nsStr struct is a simple structure (no methods) that contains
the necessary info to be described as a string. This simple struct
is manipulated by the static methods provided in this class.
(Which effectively makes this a library that works on structs).
There are also object-based versions called nsString and nsAutoString
which use nsStr but makes it look at feel like an object.
***********************************************************************/
/***********************************************************************
ASSUMPTIONS:
1. nsStrings and nsAutoString are always null terminated. However,
since it maintains a length byte, you can store NULL's inside
the string. Just be careful passing such buffers to 3rd party
API's that assume that NULL always terminate the buffer.
2. nsCStrings can be upsampled into nsString without data loss
3. Char searching is faster than string searching. Use char interfaces
if your needs will allow it.
4. It's easy to use the stack for nsAutostring buffer storage (fast too!).
See the CBufDescriptor class in this file.
5. If you don't provide the optional count argument to Append() and Insert(),
the method will assume that the given buffer is terminated by the first
NULL it encounters.
6. Downsampling from nsString to nsCString can be lossy -- avoid it if possible!
7. Calls to ToNewCString() and ToNewUnicode() should be matched with calls to nsMemory::Free().
***********************************************************************/
/**********************************************************************************
AND NOW FOR SOME GENERAL DOCUMENTATION ON STRING USAGE...
The fundamental datatype in the string library is nsStr. It's a structure that
provides the buffer storage and meta-info. It also provides a C-style library
of functions for direct manipulation (for those of you who prefer K&R to Bjarne).
Here's a diagram of the class hierarchy:
nsStr
|___nsString
| |
| ------nsAutoString
|
|___nsCString
|
------nsCAutoString
Why so many string classes? The 4 variants give you the control you need to
determine the best class for your purpose. There are 2 dimensions to this
flexibility: 1) stack vs. heap; and 2) 1-byte chars vs. 2-byte chars.
Note: While nsAutoString and nsCAutoString begin life using stack-based storage,
they may not stay that way. Like all nsString classes, autostrings will
automatically grow to contain the data you provide. When autostrings
grow beyond their intrinsic buffer, they switch to heap based allocations.
(We avoid alloca to avoid considerable platform difficulties; see the
GNU documentation for more details).
I should also briefly mention that all the string classes use a "memory agent"
object to perform memory operations. This class proxies the standard nsMemory
for actual memory calls, but knows the structure of nsStr making heap operations
more localized.
CHOOSING A STRING CLASS:
In order to choose a string class for you purpose, use this handy table:
heap-based stack-based
-----------------------------------
ascii data | nsCString nsCAutoString |
|----------------------------------
unicode data | nsString nsAutoString |
-----------------------------------
Note: The i18n folks will stenuously object if we get too carried away with the
use of nsCString's that pass interface boundaries. Try to limit your
use of these to external interfaces that demand them, or for your own
private purposes in cases where they'll never be seen by humans.
--- FAQ ---
Q. When should I use nsCString instead of nsString?
A. You should really try to stick with nsString, so that we stay as unicode
compliant as possible. But there are cases where an interface you use requires
a char*. In such cases, it's fair to use nsCString.
Q. I know that my string is going to be a certain size. Can I pre-size my nsString?
A. Yup, here's how:
{
nsString mBuffer;
mBuffer.SetCapacity(aReasonableSize);
}
Q. Should nsAutoString or nsCAutoString ever live on the heap?
A. That would be counterproductive. The point of nsAutoStrings is to preallocate your
buffers, and to auto-destroy the string when it goes out of scope.
Q. I already have a char*. Can I use the nsString functionality on that buffer?
A. Yes you can -- by using an intermediate class called CBufDescriptor.
The CBufDescriptor class is used to tell nsString about an external buffer (heap or stack) to use
instead of it's own internal buffers. Here's an example:
{
char theBuffer[256];
CBufDescritor theBufDecriptor( theBuffer, PR_TRUE, sizeof(theBuffer), 0);
nsCAutoString s3( theBufDescriptor );
s3="HELLO, my name is inigo montoya, you killed my father, prepare to die!.";
}
The assignment statment to s3 will cause the given string to be written to your
stack-based buffer via the normal nsString/nsCString interfaces. Cool, huh?
Note however that just like any other nsStringXXX use, if you write more data
than will fit in the buffer, a visit to the heap manager will be in order.
Q. What is the simplest way to get from a char* to PRUnichar*?
A. The simplest way is by construction (or assignment):
{
char* theBuf = "hello there";
nsAutoString foo(theBuf);
}
If you don't want the char* to be copied into the nsAutoString, the use a
CBufDescriptor instead.

The subsumestr class is very unusual.
It differs from a normal string in that it doesn't use normal

Instead, it "steals" the contents of the source string.

an operator+(...) for example, in that it cuts down the number

You should probably not use this class unless you really know

/*
A set of string wrapper classes that ease transition to use of XPIDL
interfaces. nsXPIDLString and nsXPIDLCString are to XPIDL `wstring'
and `string' out params as nsCOMPtr is to generic XPCOM interface
pointers. They help you deal with object ownership.
Consider the following interface:
interface nsIFoo {
attribute string Bar;
};
This will generate the following C++ header file:
class nsIFoo {
NS_IMETHOD SetBar(const PRUnichar* aValue);
NS_IMETHOD GetBar(PRUnichar* *aValue);
};
The GetBar() method will allocate a copy of the nsIFoo object's
"bar" attribute, and leave you to deal with freeing it:
nsIFoo* aFoo; // assume we get this somehow
PRUnichar* bar;
aFoo->GetFoo(&bar);
// Use bar here...
printf("bar is %s!\n", bar);
nsMemory::Free(bar);
This makes your life harder, because you need to convolute your code
to ensure that you don't leak `bar'.
Enter nsXPIDLString, which manages the ownership of the allocated
string, and automatically destroys it when the nsXPIDLString goes
out of scope:
nsIFoo* aFoo;
nsXPIDLString bar;
aFoo->GetFoo( getter_Copies(bar) );
// Use bar here...
printf("bar is %s!\n", (const char*) bar);
// no need to remember to nsMemory::Free().
Like nsCOMPtr, nsXPIDLString uses some syntactic sugar to make it
painfully clear exactly what the code expects. You need to wrap an
nsXPIDLString object with either `getter_Copies()' or
`getter_Shares()' before passing it to a getter: these tell the
nsXPIDLString how ownership is being handled.
In the case of `getter_Copies()', the callee is allocating a copy
(which is usually the case). In the case of `getter_Shares()', the
callee is returning a const reference to `the real deal' (this can
be done using the [shared] attribute in XPIDL).

In this example, you can see that unless the characters promised by |w| in |r+w| are resolved before
anything starts getting copied into |w|, there will be trouble. They will be overritten by the contents
of |r| before being retrieved to be appended.
We could have a really tricky solution where we tell the promise to resolve _just_ the data promised
by |this|, but this should be a rare case, since clients with more local knowledge will know that, e.g.,
in the case above, |Insert| could have special behavior with significantly better performance. Since
it's a rare case anyway, we should just do the simplest thing that could possibly work, resolve the
entire promise. If we measure and this turns out to show up on performance radar, we then have the
option to fix either the callers or this mechanism.

* |nsPrintfCString| lets you use a formated |printf| string as an |nsAReadableCString|.
*
* myCStr += nsPrintfCString("%f", 13.917);
* // ...a general purpose substitute for |AppendFloat|
*
* For longer patterns, you'll want to use the constructor that takes a length
*
* nsPrintfCString(128, "%f, %f, %f, %f, %f, %f, %f, %i, %f", x, y, z, 3.2, j, k, l, 3, 3.1);
*
* Exceding the default size (which you must specify in the constructor, it is not determined)
* causes an allocation, so avoid that. If your formatted string exceeds the allocated space, it is
* cut off at the size of the buffer, no error is reported (and no out-of-bounds writing occurs).
* This class is intended to be useful for numbers and short
* strings, not arbitrary formatting of other strings (e.g., with %s). There is currently no
* wide version of this class, since wide |printf| is not generally available. That means
* to get a wide version of your formatted data, you must, e.g.,
*
* CopyASCIItoUCS2(nsPrintfCString("%f", 13.917"), myStr);
*
* That's another good reason to avoid this class for anything but numbers ... as strings can be
* much more efficiently handled with |NS_LITERAL_[C]STRING| and |nsLiteral[C]String|.

There are three basic types of Event Loops that can exist in a system.
1.) There is the Main Event loop that services the application. This
is typically what would be found at the bottom of a main(). Event loops
of this type are specified with the 'MainAppLoop' type. There can only
be one of these per Application. It is also important to note that
Run() called on a Loop of this type blocks until the loop exits.
2.) User-interface threads are distinct from worker threads in that they
provide an event loop that services native system events. This is the loop
that that is found at the bottom of the ThreadMain often looking very
similar to the one found in main(). Event loops of this type are specified
with the 'ThreadLoop' type. There can only be one of these per thread.It is
also important to note that Run() called on a Loop of this type blocks
until the loop exits.
3.) The third type of loop that exists is one that is done to allow the
application and sytem to "breathe". This loop is often invoked from various
places on the stack virtually always with the main thread loop living down
the stack in some fashion. Great care should be taken in using loops of
this kind. Event loops of this type are specified with the 'AppBreathLoop'
type. There can be as many of these per application as the application
wishes to create. This loop is different than others with respect to the
way Run() works on events of this type. Run() will return once the app
has had suffiecient breathe time. This may be once the event queue is
empty or may be after a specified yield time. As loops of this type aren't
tied to the life of a thread or app, the return from Run() does not
indicate the desire to end a thread or app either.
