org.geotools.data
Class DefaultTypeEntry

java.lang.Object
  org.geotools.data.DefaultTypeEntry

All Implemented Interfaces:

CatalogEntry, TypeEntry

public class DefaultTypeEntry

extends java.lang.Object

implements TypeEntry

Default impelmentation of TypeEntry.

This implemenation is entirely dependent on the DataStore api, it does cache values and listen to events.

For an alternative take see data.store.*, AbstractDataStore2 is entirly dependendent on TypeEntry_GT.

Since:

0.3

getFeatureSource

public FeatureSource getFeatureSource()
                               throws java.io.IOException

Aquire featuresource

Specified by:

getFeatureSource in interface TypeEntry

Returns:

Throws:

java.io.IOException

See Also:

TypeEntry.getFeatureSource()

getFeatureType

public FeatureType getFeatureType()
                           throws java.io.IOException

Aquire featureType.

Specified by:

getFeatureType in interface TypeEntry

Returns:

Throws:

java.io.IOException

See Also:

TypeEntry.getFeatureType()

metadata

public java.util.Map metadata()

Access to map of metadata by name.

Specified by:

metadata in interface CatalogEntry

Returns:

Map of metadata by name

See Also:

CatalogEntry.metadata()

createMetadata

protected java.util.Map createMetadata()

Lazy creatation of metdata, subclass overrride recomended.

By default returns an empty Map

Returns:

Map of fresh metadata

getMetadataNames

public java.lang.String[] getMetadataNames()

Quick access to metadata.keySet.

Specified by:

getMetadataNames in interface CatalogEntry

Returns:

Metadata names

See Also:

CatalogEntry.getMetadataNames()

equals

public boolean equals(java.lang.Object obj)

Description copied from interface: TypeEntry

Equals based only on resource definition information (not connection information).

Specified by:

equals in interface TypeEntry

hashCode

public int hashCode()

Hashcode based on typename, uri and store.

Specified by:
