NAME: BUFFER_BASE
|
||
|
|
|
||
|
|
SYNOPSIS: Base class for transient buffer classes
|
||
|
|
|
||
|
|
INTERFACE: BUFFER_BASE()
|
||
|
|
Construct with optional size of buffer to allocate.
|
||
|
|
|
||
|
|
Resize()
|
||
|
|
Resize buffer to specified size. Returns TRUE if
|
||
|
|
successful.
|
||
|
|
|
||
|
|
QuerySize()
|
||
|
|
Return the current size of the buffer in bytes.
|
||
|
|
|
||
|
|
QueryPtr()
|
||
|
|
Return a pointer to the buffer.
|
||
|
|
|
||
|
|
PARENT: None
|
||
|
|
|
||
|
|
USES: None
|
||
|
|
|
||
|
|
CAVEATS: This is an abstract class, which unifies the interface
|
||
|
|
of BUFFER, GLOBAL_BUFFER, etc.
|
||
|
|
|
||
|
|
NOTES: In standard OOP fashion, the buffer is deallocated in
|
||
|
|
the destructor.
