public ImmutableHashMap.Mutable()

Method Detail

asImmutable

public ImmutableHashMap<K,V> asImmutable()

entrySet

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

Specified by:

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

Specified by:

entrySet in class java.util.AbstractMap<K,V>

containsKey

public boolean containsKey(java.lang.Object key)

Specified by:

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

Overrides:

containsKey in class java.util.AbstractMap<K,V>

get

public V get(java.lang.Object key)

Specified by:

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

Overrides:

get in class java.util.AbstractMap<K,V>

getEntry

public java.util.Map.Entry<K,V> getEntry(K key)

Get an entry reference.

Parameters:

key - The key to lookup.

Returns:

The found entry

getEntryReference

public ImmutableHashMap.MutableEntry<K,V> getEntryReference(K key)
                                                     throws java.lang.IllegalStateException

Get an entry reference.

The entries stored in the top level of the maps entry buckets are never deleted, only nulled. Thus references returned to them can be kept over calls to reset and used to directly access the value without a hash lookup.

This method returns only such top level entries, or null if one cannot be created. Entries that do not exist are created with null values.

Parameters:

key - The key to lookup.

Returns:

The found entry

Throws:

java.lang.IllegalStateException - if key is not a top level entry.

put

public V put(K key,
             V value)

Specified by:

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

Overrides:

put in class java.util.AbstractMap<K,V>

clear

public void clear()

Specified by:

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

Overrides:

clear in class java.util.AbstractMap<K,V>

remove

public V remove(java.lang.Object key)

Specified by:

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

Overrides:

remove in class java.util.AbstractMap<K,V>

size

public int size()

Specified by:

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

Overrides:

size in class java.util.AbstractMap<K,V>
