Method Detail

getRequiredCardinality

public int getRequiredCardinality()

Specified by:

getRequiredCardinality in class TreatFn

getErrorCodeForTypeErrors

public java.lang.String getErrorCodeForTypeErrors()

Description copied from class: TreatFn

Return the error code to be used for type errors
