$_user		The DataSift User object.

Public Methods

Method	Description
__construct ( DataSift_User $user, string $csdl = '', string $hash = false )	Constructor. A DataSift_User object is required, and you can optionally supply a default definition string.
compile ( ) : void	Call the DataSift API to compile this defintion. On success it will store the returned hash.
createHistoric ( integer $start, integer $end, array $sources, string $name, float $sample = DataSift_Historic::DEFAULT_SAMPLE ) : DataSift_Historic	Create a historic based on this CSDL.
get ( ) : string	Returns the definition string.
getBuffered ( integer $count = false, integer $from_id = false ) : array	Call the DataSift API to get buffered interactions.
getConsumer ( string $type, DataSift_IStreamConsumerEventHandler $eventHandler ) : DataSift_StreamConsumer	Returns a DataSift_StreamConsumer-derived object for this definition, for the given type.
getCreatedAt ( ) : integer	Returns the date when the stream was first created. If the created at date has not yet been obtained it validates the definition first.
getDPUBreakdown ( ) : array	Call the DataSift API to get the DPU for this definition. Returns an array containing.
getHash ( ) : string	Returns the hash for this definition. If the hash has not yet been obtained it compiles the definition first.
getTotalDPU ( ) : integer	Returns the total DPU of the stream. If the DPU has not yet been obtained it validates the definition first.
set ( string $csdl ) : void	Sets the definition string.
validate ( ) : void	Call the DataSift API to validate this defintion. On success it will store the returned hash.

Method	Description
clearHash ( ) : void	Reset the hash to false. The effect of this is to mark the definition as requiring compilation. Also resets other variables that depend on the CSDL.

protected clearHash ( ) : void
return	void

compile() public method
