WbSnakExpr

public WbSnakExpr(WbExpression<? extends org.wikidata.wdtk.datamodel.interfaces.PropertyIdValue> propExpr,
                  WbExpression<? extends org.wikidata.wdtk.datamodel.interfaces.Value> valueExpr)

Method Detail

validate

public void validate(ValidationState validation)

Description copied from interface: WbExpression

Check that this expression is fully formed and ready to be evaluated.

Specified by:

validate in interface WbExpression<org.wikidata.wdtk.datamodel.interfaces.Snak>

Parameters:

validation - the state in which to log any validation errors

evaluate

public org.wikidata.wdtk.datamodel.interfaces.Snak evaluate(ExpressionContext ctxt)
                                                     throws SkipSchemaExpressionException,
                                                            QAWarningException

Description copied from interface: WbExpression

Evaluates the value expression in a given context, returns a Wikibase value suitable to be the target of a claim. As a premise to calling that method, we assume that calling WbExpression.validate(ValidationState) did not log any error in the validation state.

Specified by:

evaluate in interface WbExpression<org.wikidata.wdtk.datamodel.interfaces.Snak>

Throws:

SkipSchemaExpressionException

QAWarningException

getProp

public WbExpression<? extends org.wikidata.wdtk.datamodel.interfaces.PropertyIdValue> getProp()

getValue

public WbExpression<? extends org.wikidata.wdtk.datamodel.interfaces.Value> getValue()

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
