Interface FilterFactory2

All Superinterfaces:
FilterFactory

public interface FilterFactory2
extends FilterFactory

Allows creation of additional Filter constructs.

Why do we need this? Because not all implementations are going to be using geoapi Geometry. This allows the creation of complient filters with SFSQL Geometry constructs. Consider this a bridge to existing projects allowing GeoAPI to be used.

Since:
GeoAPI 2.1
Version:
Implementation specification 1.1

Method Summary
 BBOX bbox(Expression geometry, BoundingBox bounds)
          Checks if the bounding box of the feature's geometry overlaps the indicated bounds.
 BBOX bbox(Expression geometry, double minx, double miny, double maxx, double maxy, String srs)
          Checks if the geometry expression overlaps the specified bounding box.
 Beyond beyond(Expression geometry1, Expression geometry2, double distance, String units)
          Check if all of a geometry is more distant than the given distance from this object's geometry.
 Contains contains(Expression geometry1, Expression geometry2)
          Checks if the the first geometric operand contains the second.
 Crosses crosses(Expression geometry1, Expression geometry2)
          Checks if the first geometric operand crosses the second.
 Disjoint disjoint(Expression geometry1, Expression geometry2)
          Checks if the first operand is disjoint from the second.
 DWithin dwithin(Expression geometry1, Expression geometry2, double distance, String units)
          Checks if any part of the first geometry lies within the given distance of the second geometry.
 Equals equal(Expression geometry1, Expression geometry2)
          Checks if the geometry of the two operands are equal.
 Intersects intersects(Expression geometry1, Expression geometry2)
          Checks if the two geometric operands intersect.
 Overlaps overlaps(Expression geometry1, Expression geometry2)
          Checks if the interior of the first geometry somewhere overlaps the interior of the second geometry.
 PropertyName property(Name name)
          Retrieves the value of a feature's property.
 Touches touches(Expression propertyName1, Expression geometry2)
          Checks if the feature's geometry touches, but does not overlap with the geometry held by this object.
 Within within(Expression geometry1, Expression geometry2)
          Checks if the feature's geometry is completely contained by the specified constant geometry.

Method Detail

property

PropertyName property(Name name)
Retrieves the value of a feature's property.


bbox

BBOX bbox(Expression geometry,
          double minx,
          double miny,
          double maxx,
          double maxy,
          String srs)
Checks if the geometry expression overlaps the specified bounding box.


bbox

BBOX bbox(Expression geometry,
          BoundingBox bounds)
Checks if the bounding box of the feature's geometry overlaps the indicated bounds.

This method does not strictly confirm to the the Filter 1.0 specification, you may use it to check expressions other than PropertyName.

Parameters:
geometry - Expression used to access a Geometry, in order to check for interaction with bounds
bounds - Indicates the bounds to check geometry against

beyond

Beyond beyond(Expression geometry1,
              Expression geometry2,
              double distance,
              String units)
Check if all of a geometry is more distant than the given distance from this object's geometry.


contains

Contains contains(Expression geometry1,
                  Expression geometry2)
Checks if the the first geometric operand contains the second.


crosses

Crosses crosses(Expression geometry1,
                Expression geometry2)
Checks if the first geometric operand crosses the second.


disjoint

Disjoint disjoint(Expression geometry1,
                  Expression geometry2)
Checks if the first operand is disjoint from the second.


dwithin

DWithin dwithin(Expression geometry1,
                Expression geometry2,
                double distance,
                String units)
Checks if any part of the first geometry lies within the given distance of the second geometry.


equal

Equals equal(Expression geometry1,
             Expression geometry2)
Checks if the geometry of the two operands are equal.

TODO:
should be equals, resolve conflict with PropertyIsEqualTo equals( Expression, Expression )

intersects

Intersects intersects(Expression geometry1,
                      Expression geometry2)
Checks if the two geometric operands intersect.


overlaps

Overlaps overlaps(Expression geometry1,
                  Expression geometry2)
Checks if the interior of the first geometry somewhere overlaps the interior of the second geometry.


touches

Touches touches(Expression propertyName1,
                Expression geometry2)
Checks if the feature's geometry touches, but does not overlap with the geometry held by this object.


within

Within within(Expression geometry1,
              Expression geometry2)
Checks if the feature's geometry is completely contained by the specified constant geometry.
