public class MultiValuedOrImpl
- extends OrImpl
A wrapper filter for filters involving nested features. Such filter involves nested attributes
that come from a different type/table, and is evaluated on the simple feature level (expecting a
single value), and join queries aren't supported. Therefore it won't work for multi-valued
attributes.. this is why NestedAttributeExpression is used to return all the possible values
(multi-valued). This wrapper filter will then get all the possible values from
NestedAttributeExpression and applies the filter for each value.

MultiValuedOrImpl
public MultiValuedOrImpl(org.opengis.filter.FilterFactory ff,
org.opengis.filter.Filter filter,
NestedAttributeExpression expression)
evaluate
public boolean evaluate(java.lang.Object feature)
- Specified by:
evaluate
in interface org.opengis.filter.Filter
- Overrides:
evaluate
in class OrImpl
accept
public java.lang.Object accept(org.opengis.filter.FilterVisitor visitor,
java.lang.Object extraData)
- Description copied from class:
LogicFilterImpl
- Used by FilterVisitors to perform some action on this filter instance.
Typicaly used by Filter decoders, but may also be used by any thing
which needs infomration from filter structure. Implementations should
always call: visitor.visit(this); It is importatant that this is not
left to a parent class unless the parents API is identical.
- Specified by:
accept
in interface org.opengis.filter.Filter
- Overrides:
accept
in class OrImpl
- Parameters:
visitor
- The visitor which requires access to this filter, the
method must call visitor.visit(this);
