getSparqlFilterExpression

String getSparqlFilterExpression(StatementMatcher.Variable<Value> variable,
 boolean negated)

Description copied from class: AbstractSimpleConstraintComponent

Simple constraints need only implement this method to support SPARQL based validation. The returned filter body should evaluate to true for values that fail validation, unless negated==true. If the filter condition throws an error (a SPARQL runtime error, not Java error) then the error will be caught and coalesced to `true`.

Specified by:

getSparqlFilterExpression in class AbstractSimpleConstraintComponent

Parameters:

variable -

negated -

Returns:

a string that is the body of a SPARQL filter

escapeRegexForSparql

private static String escapeRegexForSparql(String pattern)
