Public Properties

Property	Type	Description
$charsetid
$publicid
$publicstringid
$stringtable
$version	integer	Store the wbxml version value. Used to verify we have a valid wbxml input stream.

Protected Properties

Property	Type	Description
$_attrcp
$_buffer	stream	Temporary string buffer
$_isWbxml	boolean	Flag to indicate we have a valid wbxml input stream
$_lastStartElement	array	Cache the last successfully fetched start tag array. Used to be able to easily detected emtpy nodes after the element was already fetched.
$_readHeader
$_ungetbuffer

Public Methods

Method	Description
_ungetElement ( array $element ) : void	Unget the specified element from the stream. Places the element into the unget buffer.
getElement ( ) : array \| boolean	Returns either start, content or end, and auto-concatenates successive content.
getElementContent ( ) : mixed	Get the element contents
getElementEndTag ( ) : array \| boolean	Get the next tag, which is assumed to be an end tag.
getElementStartTag ( string $tag ) : array \| boolean	Get the next tag, which is assumed to be a start tag.
getFullInputStream ( ) : resource	Return the full, raw, input stream. Used for things like SendMail request where we don't have wbxml to parse. The calling code is responsible for closing the stream.
getLastStartElement ( ) : array \| boolean	Returns the last element array fetched using getElementStartTag()
getToken ( ) : array	Get the next [start \| content \| end] tag.
isEmptyElement ( array $el ) : boolean	Returns whether or not the passed in element array represents an empty tag.
isWbxml ( ) : boolean	Check that the input stream contains wbxml. Basically looks for a valid WBXML_VERSION header. self::readWbxmlHeader MUST have been called already.
peek ( ) : array	Peek at the next element in the stream.
readWbxmlHeader ( )	Start reading the wbxml stream, pulling off the initial header and populate the properties.

Protected Methods

Method	Description
_getAttributes ( ) : mixed	Get the element attributes
_getByte ( ) : string	Fetch a single byte from the stream.
_getMBUInt ( ) : integer	Get an MBU integer
_getMapping ( integer $cp, integer $id ) : mixed	Get a dtd mapping
_getOpaque ( integer $len ) : string	Get an opaque value from the stream of the specified length.
_getStringTable ( ) : string	Fetch the string table. Don't think we use the results anywhere though.
_getStringTableEntry ( integer $id ) : string	Really don't know for sure what this method is supposed to do, it is called from numerous places in this class, but the original zpush code did not contain this method.
_getTempStream ( ) : stream	Return the temporary buffer stream.
_getTermStr ( ) : string	Get a null terminated string from the stream.
_getToken ( ) : array	Get the next start tag, content or end tag
_logToken ( $el ) : void	Log the token.
_readVersion ( )	Read the Wbxml version header byte, and buffer the input incase we need the full stream later.
_splitAttribute ( string $attr ) : array	Parses an attribute string

Method Details
