Interface LogicFilter

All Superinterfaces:

org.opengis.filter.BinaryLogicOperator, Filter, org.opengis.filter.Filter, FilterType

All Known Implementing Classes:

LogicFilterImpl

public interface LogicFilter

extends Filter, org.opengis.filter.BinaryLogicOperator

Defines a logic filter (the only filter type that contains other filters). This filter holds one or more filters together and relates them logically with an internally defined type (AND, OR, NOT).

Method Detail

contains

public boolean contains(Feature feature)

Deprecated. use Filter.evaluate(Feature).

Determines whether the feature matches the appropriate logic relationships.

Specified by:

contains in interface Filter

Parameters:

feature - Specified feature to examine.

Returns:

Flag confirming whether or not this feature is inside the filter.

getFilterIterator

public java.util.Iterator getFilterIterator()

Gets an iterator for the filters held by this logic filter.

Returns:

the iterator of the filters.

addFilter

public void addFilter(Filter filter)
               throws IllegalFilterException

Adds a sub filter to this filter.

Parameters:

filter - Specified filter to add to the sub filter list.

Throws:

IllegalFilterException - Does not conform to logic filter structure

Task:

REVISIT: make all filters immutable. This should return a new filter.
