Member Function Documentation

Length()

virtual int64_t Azure::Core::IO::BodyStream::Length ( ) const

pure virtual

Remarks

Used with the HTTP Content-Length header.

Implemented in Azure::Core::IO::ProgressBodyStream, Azure::Core::IO::FileBodyStream, and Azure::Core::IO::MemoryBodyStream.

Read()

size_t Azure::Core::IO::BodyStream::Read ( uint8_t *  buffer, size_t  count, Azure::Core::Context const &  context = Azure::Core::Context()  )

inline

Remarks

Throws if error/cancelled.

Parameters

buffer	Pointer to a first byte of the byte buffer to read the data into.
count	Size of the buffer to read the data into.
context	A context to control the request lifetime.

Returns

Number of bytes read.

ReadToCount()

size_t BodyStream::ReadToCount	(	uint8_t *	buffer,
		size_t	count,
		Azure::Core::Context const &	context = Azure::Core::Context()
	)

Parameters

buffer	Pointer to a first byte of the byte buffer to read the data into.
count	Size of the buffer to read the data into.
context	A context to control the request lifetime.

Returns

Number of bytes read.

ReadToEnd()

std::vector< uint8_t > BodyStream::ReadToEnd

(

Azure::Core::Context const &

context = Azure::Core::Context()

)

Parameters

context

A context to control the request lifetime.

Returns

A vector of bytes containing the entirety of data read from the body.
