Method Detail

containsKey

public boolean containsKey(K key)

Blocking version of containsKeyAsync(Object). Calls containsKeyAsync(Object) and waits for the returned PgxFuture to complete.

containsKeyAsync

public PgxFuture<java.lang.Boolean> containsKeyAsync(K key)

Checks if the map contains key.

Parameters:

key - the key

Returns:

the pgx future

entries

public MapIterable<K,V> entries()

Blocking version of entriesAsync(). Calls entriesAsync() and waits for the returned PgxFuture to complete.

entriesAsync

public PgxFuture<MapIterable<K,V>> entriesAsync()

Gets an entry set.

Returns:

an iterable of the entry set

get

public V get(K key)

Blocking version of getAsync(Object). Calls getAsync(Object) and waits for the returned PgxFuture to complete.

getAsync

public PgxFuture<V> getAsync(K key)

Gets the value of a key.

Parameters:

key -

Returns:

value

getGraph

public PgxGraph getGraph()

Gets the PgxGraph this map is bound to.

Returns:

graph

getKeyType

public PropertyType getKeyType()

Gets the key type.

Returns:

the key type

getName

public java.lang.String getName()

Specified by:

getName in class PgxManagedObject

Returns:

the name identifying this managed object

getValueType

public PropertyType getValueType()

Gets the value type.

Returns:

the value type

keys

public java.lang.Iterable<K> keys()

Blocking version of keysAsync(). Calls keysAsync() and waits for the returned PgxFuture to complete.

keysAsync

public PgxFuture<java.lang.Iterable<K>> keysAsync()

remove

public boolean remove(K key)

Blocking version of removeAsync(Object). Calls removeAsync(Object) and waits for the returned PgxFuture to complete.

removeAsync

public PgxFuture<java.lang.Boolean> removeAsync(K key)

Removes the entry specified by the given key from the map with the given name. Returns true if the map did contain an entry with the given key, false otherwise.

Parameters:

key - key of the entry in the map to be removed.

Returns:

true if the map contained the key.

set

public void set(K key,
                V value)

Blocking version of setAsync(Object, Object). Calls setAsync(Object, Object) and waits for the returned PgxFuture to complete.

setAsync

public PgxFuture<java.lang.Void> setAsync(K key,
                                          V value)

Sets the value for a key in the map specified by the given name. Returns the old value for the given key or null if there was no entry for this key before.

Parameters:

key - key of the entry

value - new value

Returns:

old value for the key or null if there was no entry before

size

public int size()
