This file contains the nsStr data structure.

This general purpose buffer management class is used as the basis for our strings.

It's benefits include:

1. An efficient set of library style functions for manipulating nsStrs
|
||||
2. Support for 1 and 2 byte character strings (which can easily be increased to n)
|

3. Unicode awareness and interoperability.

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.
|
||||
2. If you try to set a null char (via SetChar()) a new length is set
|
||||
3. nsCStrings can be upsampled into nsString without data loss
|
||||
4. Char searching is faster than string searching. Use char interfaces
|
||||
if your needs will allow it.
|
||||
5. It's easy to use the stack for nsAutostring buffer storage (fast too!).
|
||||
See the CBufDescriptor class in this file.
|
||||
6. It's ONLY ok to provide non-null-terminated buffers to Append() and Insert()
|
||||
provided you specify a 0<n value for the optional count argument.
|
||||
7. Downsampling from nsString to nsCString is lossy -- avoid it if possible!
|
||||
8. Calls to ToNewCString() and ToNewUnicode() should be matched with calls to Recycle().
|
||||

||||

/**********************************************************************************
|

|

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 nsAllocator
|
||||
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.
|
||||
|
||||
|
||||
PERFORMANCE CONSIDERATIONS:
|
||||
|
||||
Here are a few tricks to know in order to get better string performance:
|
||||
|
||||
1) Try to limit conversions between ascii and unicode; By sticking with nsString
|
||||
wherever possible your code will be i18n-compliant.
|
||||
|
||||
|
||||
2) Preallocating your string buffer cuts down trips to the allocator. So if you
|
||||
have need for an arbitrarily large buffer, pre-size it like this:
|
||||
|
||||
{
|
||||
nsString mBuffer;
|
||||
mBuffer.SetCapacity(aReasonableSize);
|
||||
}
|
||||
|
||||
3) Allocating nsAutoString or nsCAutoString on the heap is memory inefficient
|
||||
(after all, the whole point is to avoid a heap allocation of the buffer).
|
||||
|
||||
|
||||
4) Consider using an autoString to write into your arbitrarily-sized stack buffers, rather
|
||||
than it's own buffers.
|
||||
|
||||
For example, let's say you're going to call printf() to emit pretty-printed debug output
|
||||
of your object. You know from experience that the pretty-printed version of your object
|
||||
exceeds the capacity of an autostring. Ignoring memory considerations, you could simply
|
||||
use nsCString, appending the stringized version of each of your class's data members.
|
||||
This will probably result in calls to the heap manager.
|
||||
|
||||
But there's a way to do this without necessarily having to call the heap manager.
|
||||
All you do is declare a stack based buffer and instruct nsCString to use that instead
|
||||
of it's own internal buffer by using the CBufDescriptor class:
|
||||
|
||||
{
|
||||
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.

|
||||
|
||||
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);
|
||||
nsAllocator::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 nsAllocator::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).

|

*
|
||||
* Much as I hate to do it, we were using string compares wrong.
|
||||
* Often, programmers call functions like strcmp(s1,s2), and pass
|
||||
* one or more null strings. Rather than blow up on these, I've
|
||||
* added quick checks to ensure that cases like this don't cause
|
||||
* us to fail.
|
||||
*
|
||||
* In general, if you pass a null into any of these string compare
|
||||
* routines, we simply return 0.

|

* The Deque is a very small, very efficient container object
|
||||
* than can hold elements of type void*, offering the following features:
|
||||
* It's interface supports pushing and poping of children.
|
||||
* It can iterate (via an interator class) it's children.
|
||||
* When full, it can efficently resize dynamically.
|
||||
*
|
||||
*
|
||||
* NOTE: The only bit of trickery here is that this deque is
|
||||
* built upon a ring-buffer. Like all ring buffers, the first
|
||||
* element may not be at index[0]. The mOrigin member determines
|
||||
* where the first child is. This point is quietly hidden from
|
||||
* customers of this class.
