Methods

getBinaryStream()

Checks what transfer-encoding decoder stream is attached on the underlying stream, and resets it if the requested arguments differ.

public getBinaryStream(string $transferEncoding) : StreamInterface
Parameters
$transferEncoding : string
Return values
StreamInterface

getContentStream()

Checks what transfer-encoding decoder stream and charset conversion stream are currently attached on the underlying stream, and resets them if the requested arguments differ from the currently assigned ones.

public getContentStream(string $transferEncoding, string $fromCharset, string $toCharset) : StreamInterface
Parameters
$transferEncoding : string
$fromCharset : string

the character set the content is encoded in

$toCharset : string

the target encoding to return

Return values
StreamInterface

reset()

Resets cached encoding and charset streams, and rewinds the stream.

public reset() : mixed
Return values
mixed

setStream()

Sets the URL used to open the content resource handle.

public setStream([StreamInterface $stream = null ]) : mixed

The function also closes the currently attached handle if any.

Parameters
$stream : StreamInterface = null
Return values
mixed

attachCharsetFilter()

Attaches a charset conversion filter to the attached content handle, for the passed arguments.

protected attachCharsetFilter(string $fromCharset, string $toCharset) : mixed
Parameters
$fromCharset : string

the character set the content is encoded in

$toCharset : string

the target encoding to return

Return values
mixed

attachTransferEncodingFilter()

Attaches a decoding filter to the attached content handle, for the passed $transferEncoding.

protected attachTransferEncodingFilter(string $transferEncoding) : mixed
Parameters
$transferEncoding : string
Return values
mixed

isCharsetFilterChanged()

Returns true if the attached stream filter used for charset conversion on the current handle is different from the one needed based on the passed arguments.

private isCharsetFilterChanged(string $fromCharset, string $toCharset) : bool
Parameters
$fromCharset : string
$toCharset : string
Return values
bool

isTransferEncodingFilterChanged()

Returns true if the attached stream filter used for decoding the content on the current handle is different from the one passed as an argument.

private isTransferEncodingFilterChanged(string $transferEncoding) : bool
Parameters
$transferEncoding : string
Return values
bool

resetCharsetStream()

Resets just the charset stream, and rewinds the decodedStream.

private resetCharsetStream() : mixed
