Detailed Description

this is a stream buf to use with std::iostream that uses a preallocated buffer under the hood.

Constructor & Destructor Documentation

PreallocatedStreamBuf() [1/3]

Aws::Utils::Stream::PreallocatedStreamBuf::PreallocatedStreamBuf	(	unsigned char *	buffer,
		uint64_t	lengthToRead
	)

Initialize the stream buffer with a pointer to your buffer. This class never takes ownership of the buffer. It is your responsibility to delete it once the stream is no longer in use.

Parameters

buffer	buffer to initialize from.
lengthToRead	length in bytes to actually use in the buffer (e.g. you have a 1kb buffer, but only want the stream to see 500 b of it.

PreallocatedStreamBuf() [2/3]

Aws::Utils::Stream::PreallocatedStreamBuf::PreallocatedStreamBuf ( const PreallocatedStreamBuf &  )

delete

PreallocatedStreamBuf() [3/3]

Aws::Utils::Stream::PreallocatedStreamBuf::PreallocatedStreamBuf ( PreallocatedStreamBuf &&  toMove )

delete

Member Function Documentation

GetBuffer()

unsigned char * Aws::Utils::Stream::PreallocatedStreamBuf::GetBuffer ( )

inline

Get the buffer that is being used by the stream buffer.

Returns

Pointer to the underlying buffer (probably for a Aws::Delete() call).
