| Method Summary | |
| public static Set | ancestors(FeatureType featureType)
| | public static boolean | equals(FeatureType typeA, FeatureType typeB)
| | public static boolean | equals(AttributeType attributesA, AttributeType attributesB)
| | public static boolean | equals(AttributeType a, AttributeType b)
| | public static boolean | equalsAncestors(FeatureType typeA, FeatureType typeB)
| | public static boolean | equalsId(FeatureType typeA, FeatureType typeB)
| | public static int | getFieldLength(AttributeType type)
This is a 'suitable replacement for extracting the expected field length of an attribute
absed on its "facets" (ie Filter describing type restrictions);
This code is copied from the ShapefileDataStore where it was written (probably by dzwiers). | | public static boolean | isDecendedFrom(FeatureType featureType, URI namespace, String typeName)
A query of the the types ancestor information. | | public static boolean | isDecendedFrom(FeatureType featureType, FeatureType isParentType)

|
| equalsAncestors | | public static boolean equalsAncestors(FeatureType typeA, FeatureType typeB)(Code) | | This method depends on the correct implementation of FeatureType equals
We may need to write an implementation that can detect cycles,
Parameters:

Parameters:
typeB - |
| getFieldLength | | public static int getFieldLength(AttributeType type)(Code) | | This is a 'suitable replacement for extracting the expected field length of an attribute
absed on its "facets" (ie Filter describing type restrictions);
This code is copied from the ShapefileDataStore where it was written (probably by dzwiers).
Cholmes is providing documentation.
Parameters:
type - the AttributeType an int indicating the max length of field in characters, or ANY_LENGTH |
| isDecendedFrom | | public static boolean isDecendedFrom(FeatureType featureType, URI namespace, String typeName)(Code) | | A query of the the types ancestor information.
This utility method may be used as common implementation for
FeatureType.isDecendedFrom( namespace, typeName ), however for specific uses,
such as GML, an implementor may be able to provide a more efficient implemenation based on
prior knolwege.
This is a proper check, if the provided FeatureType matches the given namespace and typename
it is not considered to be decended from itself.
Parameters:
featureType - typeName with parentage in question
Parameters:
namespace - namespace to match against, or null for a "wildcard"
Parameters:
typeName - typename to match against, or null for a "wildcard" true if featureType is a decendent of the indicated namespace & typeName |
