Class FilteredCodes

java.lang.Object

org.apache.sis.internal.util.AbstractMap<String,Boolean>

org.apache.sis.referencing.factory.FilteredCodes

All Implemented Interfaces:

Map<String,Boolean>

final class FilteredCodes
extends AbstractMap<String,Boolean>

A map of authority codes filtered by their type. This map is used for implementation of CommonAuthorityFactory.getAuthorityCodes(Class). Only keys in this map are useful; values are meaningless.

FilteredCodes

FilteredCodes(Map<String,Class<?>> codes,
 Class<?> type)

Creates a new filtered view over the given authority codes.

Method Details

entryIterator

protected AbstractMap.EntryIterator<String,Boolean> entryIterator()

Returns an iterator over the entries to retain. Values in the returned entries are meaningless; only the keys matter.

Specified by:

entryIterator in class AbstractMap<String,Boolean>

Returns:

an iterator over the entries in this map, or null.

get

public Boolean get(Object key)

Returns a non-null value if the given code is included in the set.
