Member Typedef Documentation

◆ CheckerCallback

using PartCheckerStream::CheckerCallback = Delegate<bool(const HttpHeaders& headers, ReadWriteStream* source, const FilePart& filePart)>

Constructor & Destructor Documentation

◆ PartCheckerStream()

PartCheckerStream::PartCheckerStream	(	ReadWriteStream *	source,
		CheckerCallback	callback
	)

inline

Parameters

callback
stream	- The actual stream doing the work. The stream is owned and will be deleted here

Member Function Documentation

◆ checkHeaders()

bool PartCheckerStream::checkHeaders	(	const HttpHeaders &	headers,
		const FilePart &	part
	)

inline

◆ getStreamType()

StreamType PartCheckerStream::getStreamType ( ) const

inlineoverridevirtual

Get the stream type.

Return values

StreamType The stream type.

Reimplemented from StreamWrapper.

◆ isFinished()

bool PartCheckerStream::isFinished ( )

inlineoverridevirtual

Check if all data has been read.

Return values

bool	True on success.

Reimplemented from StreamWrapper.

◆ isValid()

bool PartCheckerStream::isValid ( ) const

inlineoverridevirtual

Determine if the stream object contains valid data.

Return values

bool	true if valid, false if invalid

Note: Where inherited classes are initialised by constructor this method indicates whether that was successful or not (e.g. FileStream)

Reimplemented from IDataSourceStream.

◆ readMemoryBlock()

uint16_t PartCheckerStream::readMemoryBlock	(	char *	data,
		int	bufSize
	)

inlineoverridevirtual

Read a block of memory.

Parameters

data	Pointer to the data to be read
bufSize	Quantity of chars to read

Return values

uint16_t Quantity of chars read

Todo:: Should IDataSourceStream::readMemoryBlock return same data type as its bufSize param?

Reimplemented from StreamWrapper.

◆ write()

size_t PartCheckerStream::write	(	const uint8_t *	buffer,
		size_t	size
	)

inlineoverridevirtual

Write chars to stream.

Parameters

buffer	Pointer to buffer to write to the stream
size	Quantity of chars to write

Return values

size_t Quantity of chars written to stream

Note: Although this is defined in the Print class, ReadWriteStream uses this as the core output method so descendants are required to implement it

Implements ReadWriteStream.
