get a comparison key for an object . this must satisfy the rule that if two objects are equal according to the xpath eq operator , then their comparison keys are equal according to the java equals method , and vice versa . there is no requirement that the comparison keys should reflect the ordering of the underlying objects . concode_field_sep AtomicComparer baseComparer concode_field_sep AtomicComparer getBaseComparer concode_elem_sep int compareAtomicValues concode_elem_sep boolean comparesEqual concode_elem_sep AtomicComparer provideContext
ComparisonKey function ( AtomicValue arg0 ) { return ( arg0 == null ? new ComparisonKey ( Type . EMPTY , "srini_string" ) : baseComparer . getComparisonKey ( arg0 ) ) ; }
