-//////////////////////////////////////////////////////////////////////////////////////////////
-// The icon decoder is a decoder specifically tailored for loading icons 
-// from the OS. We've defined our own little format to represent these icons
-// and this decoder takes that format and converts it into 24-bit RGB with alpha channel
-// support. It was modeled a bit off the PPM decoder.
-//
-// Assumptions about the decoder:
-// (1) We receive ALL of the data from the icon channel in one OnDataAvailable call. We don't
-//     support multiple ODA calls yet.
-// (2) the format of the incoming data is as follows:
-//     The first two bytes contain the width and the height of the icon. 
-//     Followed by 3 bytes per pixel for the color bitmap row after row. (for heigh * width * 3 bytes)
-//     Followed by bit mask data (used for transparency on the alpha channel). 
-//

-/*-----------------------------------------------------------------------------
- * This is the callback routine from the IJG JPEG library used to supply new
- * data to the decompressor when its input buffer is exhausted.  It juggles
- * multiple buffers in an attempt to avoid unnecessary copying of input data.
- *
- * (A simpler scheme is possible: It's much easier to use only a single
- * buffer; when fill_input_buffer() is called, move any unconsumed data
- * (beyond the current pointer/count) down to the beginning of this buffer and
- * then load new data into the remaining buffer space.  This approach requires
- * a little more data copying but is far easier to get right.)
- *
- * At any one time, the JPEG decompressor is either reading from the necko
- * input buffer, which is volatile across top-level calls to the IJG library,
- * or the "backtrack" buffer.  The backtrack buffer contains the remaining
- * unconsumed data from the necko buffer after parsing was suspended due
- * to insufficient data in some previous call to the IJG library.
- *
- * When suspending, the decompressor will back up to a convenient restart
- * point (typically the start of the current MCU). The variables
- * next_input_byte & bytes_in_buffer indicate where the restart point will be
- * if the current call returns FALSE.  Data beyond this point must be
- * rescanned after resumption, so it must be preserved in case the decompressor
- * decides to backtrack.
- *
- * Returns:
- *  TRUE if additional data is available, FALSE if no data present and
- *   the JPEG library should therefore suspend processing of input stream

+  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.

+/*
+
+  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).
