Decorator used to return only a subset of a stream.

CloneableFinalInstantiable
Methods
public __call(string $method, array $args)
 

Allow decorators to implement custom methods

  • return mixed
public __construct(Psr\Http\Message\StreamInterface $stream, int $limit = -1, int $offset = 0)
 
  • param \StreamInterface $stream Stream to wrap
  • param int $limit Total number of bytes to allow to be read from the stream. Pass -1 for no limit.
  • param int $offset Position to seek to before reading (only works on seekable streams).
public __get(string $name)
 

Magic method used to create a new stream if streams are not added in the constructor of a decorator (e.g., LazyOpenStream).

  • return \StreamInterface
public __toString() : string
public close() : void
public detach()
public eof() : bool
public getContents() : string
public getMetadata( $key = NULL)
 
  • return mixed
public getSize() : ?int
 

Returns the size of the limited subset of data

public isReadable() : bool
public isSeekable() : bool
public isWritable() : bool
public read( $length) : string
public rewind() : void
public seek( $offset, $whence = 0GuzzleHttp\Psr7\SEEK_SET) : void
 

Allow for a bounded seek on the read limited stream

public setLimit(int $limit) : void
 

Set the limit of bytes that the decorator allows to be read from the stream.

  • param int $limit Number of bytes to allow to be read from the stream. Use -1 for no limit.
public setOffset(int $offset) : void
 

Set the offset to start limiting from

  • param int $offset Offset to seek to and begin byte limiting from
  • throws \RuntimeException if the stream cannot be seeked.
public tell() : int
 

Give a relative tell()

public write( $string) : int
Methods
protected createStream() : Psr\Http\Message\StreamInterface
 

Implement in subclasses to dynamically create streams when requested.

  • throws \BadMethodCallException
Properties
private $limit = NULL
 
  • var int Limit the number of bytes that can be read
private $offset = NULL
 
  • var int Offset to start reading from
private $stream = NULL
 
  • var \StreamInterface
