Method Detail

getValueExpressionNode

public abstract IValueExpressionNode getValueExpressionNode()

getRequiredValueExpression

public final IValueExpression<? extends IV> getRequiredValueExpression()

Return the IValueExpression.

Returns:

The IValueExpression and never null.

Throws:

IllegalStateException - if the IValueExpression is not set on this node.

getConsumedVars

public Set<IVariable<?>> getConsumedVars()

Description copied from interface: IValueExpressionMetadata

Return the set of variables that will be used by this constraint to determine which solutions will continue on through the pipeline and which will be filtered out.

Specified by:

getConsumedVars in interface IValueExpressionMetadata

getMaterializationRequirement

public ComputedMaterializationRequirement getMaterializationRequirement()

Description copied from interface: IValueExpressionMetadata

Return the materialization requirement for this filter. Many filters require materialized variables to do their filtering. Some filters can work on both materialized terms and internal values (a good example of this is CompareBOp).

Specified by:

getMaterializationRequirement in interface IValueExpressionMetadata
