Public Member Functions

IProtonBuffer Fill (byte value)
 Fill the buffer with the given byte value. This method does not respect the read offset nor the write offset but instead fills the entire backing buffer memory with the given value.
 
IProtonBuffer Reset ()
 Resets the read and write offset values to zero.
 
IProtonBuffer SkipBytes (long amount)
 Advance the buffer read offset by the specified amount effectively skipping that number of bytes from being read.
 
IProtonCompositeBuffer Append (IProtonBuffer buffer)
 Appends the provided buffer to the end of the list of composite buffers already managed by this buffer. The given buffer becomes the property of the composite and the constraints placed upon buffers managed by the composite implementation are extended to this appended buffer.
 
IProtonBuffer Compact ()
 Discards the read bytes, and moves the buffer contents to the beginning of the buffer.
 
IProtonBuffer Reclaim ()
 Reclaims read buffer space and returns it to the operating system or other pooling mechanisms if those are in place, then compacts the remaining buffer contents. For a non-composite buffer this operation could consist of allocating a smaller buffer to house any remaining unread bytes and freeing the larger backing buffer in some cases or it may result in a no-op depending on the buffer implementation. For the composite buffer case this operation provides an API which allows for fully read buffer constituents to be released and returned to a memory pool or back to the O/S.
 
IProtonBuffer WriteSplit (long offset)
 Splits the buffer into two distinct buffers at the given index plus the current write offset. The returned buffer will retain the read offset and write offset of this buffer but will be truncated to match the capacity provided by the split index, which implies that they might both be set to the capacity if they were previously set to the split index. The returned buffer will set its read and write offsets to zero if they fell prior to the given index otherwise they will be truncated to match the new buffer capacity. Split buffers support the standard buffer operations including resizing to ensure writable regions which implies that a buffer resize on either will cause them to no longer reference the same underlying memory region. If buffer implementations implement pooling then they must ensure proper release of shared buffer regions once both buffers no longer reference them.
 
IProtonBuffer ReadSplit (long offset)
 Splits the buffer into two distinct buffers at the given index plus the current read offset. The returned buffer will retain the read offset and write offset of this buffer but will be truncated to match the capacity provided by the split index, which implies that they might both be set to the capacity if they were previously set beyond the split index. The returned buffer will set its read and write offsets to zero if they fell prior to the given index otherwise they will be truncated to match the new buffer capacity. Split buffers support the standard buffer operations including resizing to ensure writable regions which implies that a buffer resize on either will cause them to no longer reference the same underlying memory region. If buffer implementations implement pooling then they must ensure proper release of shared buffer regions once both buffers no longer reference them.
 
IProtonBuffer Split ()
 Splits the buffer into two buffers at the write offset. The resulting buffer will comprise the read and readable portions of this buffer with the write offset and capacity set to the current write offset. This buffer will lose access to the split region and its read offset will be set to the current write offset. This buffer will also have its capacity reduced by the number of bytes in the returned buffer (i.e. the current number of read and readable bytes). Split buffers support the standard buffer operations including resizing to ensure writable regions which implies that a buffer resize on either will cause them to no longer reference the same underlying memory region. If buffer implementations implement pooling then they must ensure proper release of shared buffer regions once both buffers no longer reference them.

◆ ReadSplit()

IProtonBuffer Apache.Qpid.Proton.Buffer.ProtonCompositeBuffer.ReadSplit ( long  offset)
inline

Splits the buffer into two distinct buffers at the given index plus the current read offset. The returned buffer will retain the read offset and write offset of this buffer but will be truncated to match the capacity provided by the split index, which implies that they might both be set to the capacity if they were previously set beyond the split index. The returned buffer will set its read and write offsets to zero if they fell prior to the given index otherwise they will be truncated to match the new buffer capacity. Split buffers support the standard buffer operations including resizing to ensure writable regions which implies that a buffer resize on either will cause them to no longer reference the same underlying memory region. If buffer implementations implement pooling then they must ensure proper release of shared buffer regions once both buffers no longer reference them.

Parameters

For a non-composite buffer this operation could consist of allocating a smaller buffer to house any remaining unread bytes and freeing the larger backing buffer in some cases or it may result in a no-op depending on the buffer implementation. For the composite buffer case this operation provides an API which allows for fully read buffer constituents to be released and returned to a memory pool or back to the O/S.
