visit

public void visit(Filter filter)

Description copied from interface: FilterVisitor

Called when accept is called on an AbstractFilter. As it is imposible to create an instance of AbstractFilter this should never happen. If it does it means that a subclass of AbstractFilter has failed to implement accept(FilterVisitor) correctly. Implementers of this method should probaly log a warning.

Specified by:

visit in interface FilterVisitor

Parameters:

filter - The filter to visit

See Also:

FilterVisitor.visit(org.geotools.filter.Filter)

visit

public void visit(BetweenFilter filter)

Description copied from interface: FilterVisitor

Called when accept is called on a BetweenFilter. Implementers will want to access the left, middle and right expresions.

Specified by:

visit in interface FilterVisitor

Parameters:

filter - The filter to visit

See Also:

FilterVisitor.visit(org.geotools.filter.BetweenFilter)

visit

public void visit(CompareFilter filter)

Description copied from interface: FilterVisitor

Called when accept is called on a Compare Filter. Implementers will want to access the left and right expresions.

Specified by:

visit in interface FilterVisitor

Parameters:

filter - The filter to visit

See Also:

FilterVisitor.visit(org.geotools.filter.CompareFilter)

visit

public void visit(GeometryFilter filter)

Description copied from interface: FilterVisitor

Called when accept is called on a Geometry Filter. Implementers will want to access the left and right geometries.

Specified by:

visit in interface FilterVisitor

Parameters:

filter - The filter to visit

See Also:

FilterVisitor.visit(org.geotools.filter.GeometryFilter)

visit

public void visit(LikeFilter filter)

Description copied from interface: FilterVisitor

Called when accept is called on a Like Filter. Implementers will want to access the pattern and value.

Specified by:

visit in interface FilterVisitor

Parameters:

filter - The filter to visit.

See Also:

FilterVisitor.visit(org.geotools.filter.LikeFilter)

visit

public void visit(LogicFilter filter)

Description copied from interface: FilterVisitor

Called when accept is called on a Logic Filter. Implementers will want to access the sub filters.

Specified by:

visit in interface FilterVisitor

Parameters:

filter - The filter to visit.

See Also:

FilterVisitor.visit(org.geotools.filter.LogicFilter)

visit

public void visit(NullFilter filter)

Description copied from interface: FilterVisitor

Called when accept is called on a Null Filter. Implementers will want to access the null check.

Specified by:

visit in interface FilterVisitor

Parameters:

filter - The filter to visit.

See Also:

visit

public void visit(FidFilter filter)

Description copied from interface: FilterVisitor

Called when accept is called on a Fid Filter. Implementers will want to access the fids.

Specified by:

visit in interface FilterVisitor

Parameters:

filter - The filter to visit.

visit

public void visit(AttributeExpression expression)

Description copied from interface: FilterVisitor

Called when accept is called on an attribute expression. Implementors will want to access the attribute.

Specified by:

visit in interface FilterVisitor

Parameters:

expression - The expression to visit.

See Also:

FilterVisitor.visit(org.geotools.filter.expression.AttributeExpression)

visit

public void visit(Expression expression)

Description copied from interface: FilterVisitor

This should never be called. This can only happen if a subclass of DefaultExpression fails to implement its own version of accept(FilterVisitor);

Specified by:

visit in interface FilterVisitor

Parameters:

expression - the expression to visit.

See Also:

FilterVisitor.visit(org.geotools.filter.expression.Expression)

visit

public void visit(LiteralExpression expression)

Description copied from interface: FilterVisitor

Called when accept is called on a literal expression. Implementors will want to access the literal.

Specified by:

visit in interface FilterVisitor

Parameters:

expression - The expression to visit.

See Also:

FilterVisitor.visit(org.geotools.filter.expression.LiteralExpression)

visit

public void visit(MathExpression expression)

Description copied from interface: FilterVisitor

Called when accept is called on an math expression.

Specified by:

visit in interface FilterVisitor

Parameters:

expression - The expression to visit.

See Also:

FilterVisitor.visit(org.geotools.filter.expression.MathExpression)

visit

public void visit(FunctionExpression expression)

Description copied from interface: FilterVisitor

Called when accept is called on an function expression.

Specified by:

visit in interface FilterVisitor

Parameters:

expression - The expression to visit.
