Field Details

BBOX

@UML(identifier="BBOX",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SpatialOperatorName BBOX

Operator evaluates to true when the bounding box of the feature's geometry interacts with the bounding box provided in the filter properties. The geometry is given by the first expression and the bounding box is the envelope given by the second expression.

The BBOX operation is defined as a convenient and more compact way of expressing the very common bounding box constraint based on the envelope geometry. It is equivalent to the spatial operation NOT DISJOINT meaning that the BBOX operator identifies all geometries that spatially interact with the box.

An implementation may choose to throw an exception if one attempts to test features that are in a different SRS than the SRS contained in the filter.

EQUALS

@UML(identifier="Equals",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SpatialOperatorName EQUALS

Operator evaluates to true if the geometry of the two operands are equal.

DISJOINT

@UML(identifier="Disjoint",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SpatialOperatorName DISJOINT

Operator evaluates to true if the first operand is disjoint from the second. "Disjoint" shall be interpreted in the sense defined in the OGC Simple Features specification.

INTERSECTS

@UML(identifier="Intersects",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SpatialOperatorName INTERSECTS

Operator evaluates to true if the two geometric operands intersect.

TOUCHES

@UML(identifier="Touches",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SpatialOperatorName TOUCHES

Operator evaluates to true if the two geometric operands touch, but do not overlap.

CROSSES

@UML(identifier="Crosses",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SpatialOperatorName CROSSES

Operator evaluates to true if the first geometric operand crosses the second. "Cross" shall be interpreted in the sense defined by the OGC Simple Features specification.

WITHIN

@UML(identifier="Within",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SpatialOperatorName WITHIN

Operator evaluates to true if the first geometric operand is completely contained by the constant geometric operand.

CONTAINS

@UML(identifier="Contains",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SpatialOperatorName CONTAINS

Operator evaluates to true if the first geometric operand contains the second.

OVERLAPS

@UML(identifier="Overlaps",
     obligation=CONDITIONAL,
     specification=ISO_19143)
public static final SpatialOperatorName OVERLAPS

Operator evaluates to true if the interior of the first geometric operand somewhere overlaps the interior of the second geometric operand.

Method Details

values

public static SpatialOperatorName[] values()

Returns the list of SpatialOperatorNames.

Returns:

the list of codes declared in the current JVM.

family

public SpatialOperatorName[] family()

Returns the list of codes of the same kind as this code list element. Invoking this method is equivalent to invoking values(), except that this method can be invoked on an instance of the parent CodeList class.

Specified by:

family in interface ControlledVocabulary

Specified by:

family in class CodeList<SpatialOperatorName>

Returns:

all code values for this code list.

valueOf

public static SpatialOperatorName valueOf(String code)

Returns the spatial operator that matches the given string, or returns a new one if none match it. This methods returns the first instance (in declaration order) for which the name is equals, ignoring case, to the given name. If no existing instance is found, then a new one is created for the given name.

Parameters:

code - the name of the code to fetch or to create.

Returns:

a code matching the given name.
