Constructor Summary

VectorMultiMap()
Default constructor, creates an empty VectorMultiMap.

VectorMultiMap(MultiMap multimap)

Method Summary

java.util.Set	entrySet() Returns a set view of the mappings contained in this multimap.
java.util.List	getValueList(java.lang.Object key) Get the values for a key as a list
java.util.Set	put(java.lang.Object key, java.lang.Object value) Associates the specified value with the specified key in this map (optional operation).

Constructor Detail

VectorMultiMap

public VectorMultiMap()

Default constructor, creates an empty VectorMultiMap.

VectorMultiMap

public VectorMultiMap(MultiMap multimap)

Constructor, creates a VectorMultiMap with the same mapping as the given multimap.

Parameters:

multimap - The multimap whose mappings we want to copy.

Method Detail

put

public java.util.Set put(java.lang.Object key,
                         java.lang.Object value)

Associates the specified value with the specified key in this map (optional operation). If the multimap previously contained a mapping for this key, the old value is not lost.

This implementation always throws an UnsupportedOperationException.

Specified by:

put in interface MultiMap

Overrides:

put in class AbstractMultiMap

Parameters:

key - Key with which the specified value is to be associated.

value - Value to be associated with the specified key.

Returns:

Set of values associated with the specified key.

getValueList

public java.util.List getValueList(java.lang.Object key)

Get the values for a key as a list

Parameters:

key - The key

Returns:

A List of the values

entrySet

public java.util.Set entrySet()

Returns a set view of the mappings contained in this multimap. Each element in this set is a MultiMap.Entry. The set is backed by the map, so changes to the multimap are reflected in the set, and vice-versa. (If the map is modified while an iteration over the set is in progress, the results of the iteration are undefined.) The set supports element removal, which removes the corresponding entry from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

Specified by:

entrySet in interface MultiMap

Specified by:

entrySet in class AbstractMultiMap

Returns:

A set view of the mappings contained in this multimap.
