INSTANCE

public static final URIMappingRegistryImpl INSTANCE

The implementation of the global mapping registry.

prefixMaps

protected BasicEList<java.util.List<BasicEMap.Entry<URI,URI>>> prefixMaps

A list of lists of prefix URIs; it is indexed by segment count to yield a list of prefixes of that length.

Constructor Detail

URIMappingRegistryImpl

public URIMappingRegistryImpl()

Creates an instance.

Method Detail

newEntry

protected BasicEMap.Entry<URI,URI> newEntry(int hash,
                                URI key,
                                URI value)

Creates an URIMappingRegistryImpl.MappingEntryImpl.

Overrides:

newEntry in class BasicEMap<URI,URI>

Parameters:

hash - the cached hash code of the key.

key - the key.

value - the value.

Returns:

a new entry.

See Also:

BasicEMap.newList()

getURI

public URI getURI(URI uri)

Returns the remapped URI, or the URI itself. This implementation uses the map to find an exact match. Failing that, it matches the prefixMaps prefixes in order. And failing that, it delegates to delegatedGetURI.

Parameters:

uri - the URI to remap.

Returns:

the remapped URI, or the URI itself.

delegatedGetURI

protected URI delegatedGetURI(URI uri)

Returns the mapped URI for the given URI, when standard alternatives fail.

This implementation returns uri.

Parameters:

uri - the URI.

Returns:

the mapped URI.

See Also:

getURI(URI)

map

public java.util.Map<URI,URI> map()

Returns a map view that implements ExtensibleURIConverterImpl.URIMap.

Specified by:

map in interface EMap<URI,URI>

Overrides:

map in class BasicEMap<URI,URI>

Returns:

a map view.

validateKey

protected void validateKey(URI key)

Validates that the key is a URI.

Overrides:

validateKey in class BasicEMap<URI,URI>

Parameters:

key - the new key.

validateValue

protected void validateValue(URI value)

Validates that the value is a URI.

Overrides:

validateValue in class BasicEMap<URI,URI>

Parameters:

value - the new value.

didAdd

protected void didAdd(BasicEMap.Entry<URI,URI> entry)

Checks for folder mappings to populate the prefix maps.

Overrides:

didAdd in class BasicEMap<URI,URI>

Parameters:

entry - the added entry.

didModify

protected void didModify(BasicEMap.Entry<URI,URI> entry,
             URI oldValue)

Checks for folder mappings to update the prefix maps.

Overrides:

didModify in class BasicEMap<URI,URI>

Parameters:

entry - the new entry.

didRemove

protected void didRemove(BasicEMap.Entry<URI,URI> entry)

Checks for folder mappings to cleanup the prefix maps.

Overrides:

didRemove in class BasicEMap<URI,URI>

Parameters:

entry - the removed entry.

didClear

protected void didClear(BasicEList<BasicEMap.Entry<URI,URI>>[] oldEntryData)

Discards all the prefix maps.

Overrides:

didClear in class BasicEMap<URI,URI>

Parameters:

oldEntryData - the removed entries.

modificationCount

protected int modificationCount()

Provides access to the modification count for use in URIMappingRegistryImpl.URIMapImpl.modificationCount().
