Class DeltaCollectionValuedMap<K,V>

java.lang.Object
  edu.stanford.nlp.util.CollectionValuedMap<K,V>
      edu.stanford.nlp.util.DeltaCollectionValuedMap<K,V>

All Implemented Interfaces:

java.io.Serializable, java.util.Map<K,java.util.Collection<V>>

public class DeltaCollectionValuedMap<K,V>
extends CollectionValuedMap<K,V>

Implementation of CollectionValuedMap that appears to store an "original" map and changes to that map. No one currently uses it. See DeltaMap.

DeltaCollectionValuedMap

public DeltaCollectionValuedMap(CollectionValuedMap<K,V> originalMap)

Method Detail

get

public java.util.Collection<V> get(java.lang.Object key)

Specified by:

get in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

get in class CollectionValuedMap<K,V>

Returns:

the Collection mapped to by key, never null, but may be empty.

put

public java.util.Collection<V> put(K key,
                                   java.util.Collection<V> value)

Description copied from class: CollectionValuedMap

Replaces current Collection mapped to key with the specified Collection. Use carefully!

Specified by:

put in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

put in class CollectionValuedMap<K,V>

putAll

public void putAll(java.util.Map<? extends K,? extends java.util.Collection<V>> m)

Description copied from class: CollectionValuedMap

Unsupported. Use CollectionValuedMap.addAll(Map) instead.

Specified by:

putAll in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

putAll in class CollectionValuedMap<K,V>

add

public void add(K key,
                V value)

Description copied from class: CollectionValuedMap

Adds the value to the Collection mapped to by the key.

Overrides:

add in class CollectionValuedMap<K,V>

addAll

public void addAll(java.util.Map<K,V> m)

Adds all of the mappings in m to this CollectionValuedMap. If m is a CollectionValuedMap, it will behave strangely. Use the constructor instead.

Overrides:

addAll in class CollectionValuedMap<K,V>

remove

public java.util.Collection<V> remove(java.lang.Object key)

Description copied from class: CollectionValuedMap

Removes the mapping associated with this key from this Map.

Specified by:

remove in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

remove in class CollectionValuedMap<K,V>

Returns:

the Collection mapped to by this key.

removeMapping

public void removeMapping(K key,
                          V value)

Description copied from class: CollectionValuedMap

Removes the value from the Collection mapped to by this key, leaving the rest of the collection intact.

Overrides:

removeMapping in class CollectionValuedMap<K,V>

Parameters:

key - the key to the Collection to remove the value from

value - the value to remove

containsKey

public boolean containsKey(java.lang.Object key)

Specified by:

containsKey in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

containsKey in class CollectionValuedMap<K,V>

Returns:

true iff this key is in this map

containsValue

public boolean containsValue(java.lang.Object value)

Description copied from class: CollectionValuedMap

Unsupported.

Specified by:

containsValue in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

containsValue in class CollectionValuedMap<K,V>

clear

public void clear()

This is more expensive than normal.

Specified by:

clear in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

clear in class CollectionValuedMap<K,V>

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

isEmpty in class CollectionValuedMap<K,V>

Returns:

true iff this Map has no mappings in it.

size

public int size()

Description copied from class: CollectionValuedMap

The number of keys in this map.

Specified by:

size in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

size in class CollectionValuedMap<K,V>

values

public java.util.Collection<java.util.Collection<V>> values()

Specified by:

values in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

values in class CollectionValuedMap<K,V>

Returns:

a collection of the values (really, a collection of values) in this Map

entrySet

public java.util.Set<java.util.Map.Entry<K,java.util.Collection<V>>> entrySet()

This is cheap.

Specified by:

entrySet in interface java.util.Map<K,java.util.Collection<V>>

Overrides:

entrySet in class CollectionValuedMap<K,V>

Returns:

a set view of the mappings contained in this map.
