Constructor & Destructor Documentation

__construct()

GuzzleHttp\Psr7\LimitStream::__construct	(	StreamInterface	$stream,
		int	$limit = -1,
		int	$offset = 0 )

Parameters

StreamInterface	$stream	Stream to wrap
int	$limit	Total number of bytes to allow to be read from the stream. Pass -1 for no limit.
int	$offset	Position to seek to before reading (only works on seekable streams).

Member Function Documentation

__toString()

Psr\Http\Message\StreamInterface::__toString ( )

inherited

Reads all data from the stream into a string, from the beginning to end.

This method MUST attempt to seek to the beginning of the stream before reading data and read the stream until the end is reached.

Warning: This could attempt to load a large amount of data into memory.

This method MUST NOT raise an exception in order to conform with PHP's string casting operations.

read()

GuzzleHttp\Psr7\LimitStream::read

(

$length

)

Read data from the stream.

Parameters

int

$length

Read up to $length bytes from the object and return them. Fewer than $length bytes may be returned if underlying stream call returns fewer bytes.

Return values

string

Returns the data read from the stream, or an empty string if no bytes are available.

Exceptions

RuntimeException

if an error occurs.

Implements Psr\Http\Message\StreamInterface.

rewind()

Psr\Http\Message\StreamInterface::rewind ( )

inherited

Seek to the beginning of the stream.
