C# Class LazyCopy.Utilities.ResizableBuffer

This class maintains its own internal buffer and extends it, if the it is too small to fit the desired data.
The main reason of using this class is to avoid unnecessary memory allocations.
For example, the same memory can be used for getting the driver notification and then storing the reply message into, so there's no need to allocate two separate memory blocks.

Méthodes publiques

Méthode Description
DangerousGetPointer ( ) : IntPtr

Gets the pointer to the internal buffer.

Be careful with the pointer returned, because it may become invalid after the next Resize function call and after the ResizableBuffer instance is disposed.

Dispose ( ) : void

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
ResizableBuffer ( ) : System

Initializes a new instance of the ResizableBuffer class.

The Environment.SystemPageSize is passed as an initial size.

ResizableBuffer ( int initialSize ) : System

Initializes a new instance of the ResizableBuffer class.
Resize ( int newSize ) : void

Resizes the buffer.

Be careful with the pointer returned, because it may become invalid after the next Resize function call and after the ResizableBuffer instance is disposed.

Méthodes protégées

Méthode Description
Dispose ( bool disposing ) : void

Releases unmanaged and - optionally - managed resources.

Private Methods

Méthode Description
EnsureBufferIsOfTheRightSize ( int newSize ) : void

Ensures that the current buffer can store the newSize bytes. If the current buffer is not large enough, it's extended.
