Description copied from interface: FarragoTransform

Binds all inputs and initializes the transform. This method is typically generated. It is called by FarragoExecutableJavaStmt.execute(net.sf.farrago.session.FarragoSessionRuntimeContext).

Specified by:

init in interface FarragoTransform

Parameters:

connection - the FarragoRuntimeContext of the query that contains this transform.

farragoTransformStreamName - the globally unique name of the ExecStream that implements this transform.

inputBindings - bindings between the transform's input streamIds and the ordinal assigned to them in the stream graph
