Method Detail

computeStreamability

public PostureAndSweep computeStreamability(ContextItemStaticInfoEE contextInfo,
                                            java.util.List<java.lang.String> reasons)

Get the posture and sweep of this expression as defined in the W3C streamability specifications. This provides an assessment of stylesheet code against the W3C criteria for guaranteed streamability, and is implemented to allow these criteria to be tested. It is not the case that all expression that emerge as streamable from this analysis are currently capable of being streamed by Saxon

Overrides:

computeStreamability in class StreamingAdjunct

Parameters:

contextInfo - Information about the context item for the expression

reasons - the caller may supply a list, in which case the implementation may add to this

Returns:

the posture and sweep of the expression
