isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface LongObjMap<T>

Returns:

true if this map contains no elements

containsKeys

public boolean containsKeys(LongIterable iterable)

Specified by:

containsKeys in interface LongObjMap<T>

Returns:

true if this map contains all of the elements produced by keys. Otherwise false

keySet

public LongSet keySet()

Specified by:

keySet in interface LongObjMap<T>

Returns:

a LongSet view of the keys contained in this map.

modified

protected void modified()

put

public T put(long key,
    T value)

Description copied from interface: WritableLongObjMap

Associates the specified value with the specified key in this map.

Specified by:

put in interface WritableLongObjMap<T>

Returns:

the previous value associated with key, or default value if there was no mapping for key.

putIfAbsent

public boolean putIfAbsent(long key,
                  T value)

Description copied from interface: WritableLongObjMap

Associates the specified value with the specified key only if the specified key has no current mapping.

Specified by:

putIfAbsent in interface WritableLongObjMap<T>

Returns:

true if the size of this map has changed. Otherwise false.

add

public AbstractWritableLongObjMap<T> add(long key,
                                T value)

Description copied from interface: WritableLongObjMap

Associates the specified value with the specified key in this map.

Specified by:

add in interface WritableLongObjMap<T>

Returns:

this

remove

public T remove(long key)

Description copied from interface: WritableLongObjMap

Removes value for the given key. The default value is returned if the key does not exist in this map.

Specified by:

remove in interface WritableLongObjMap<T>

Returns:

old value for the specified key if this map contained the key. Otherwise returns default value.

remove

public boolean remove(long key,
             T value)

Description copied from interface: WritableLongObjMap

Removes the entry for the key only if the key is currently mapped to the given value.

Specified by:

remove in interface WritableLongObjMap<T>

Returns:

true if the size of this map has changed. Otherwise false.

putAll

public void putAll(LongObjIterable<T> entries)

Description copied from interface: WritableLongObjMap

Puts all keys from the specified iterable to this map, replacing the values of existing keys, if such keys are present.

Specified by:

putAll in interface WritableLongObjMap<T>

putAll

public void putAll(LongSizedIterable keys,
          java.util.Collection<T> values)

Specified by:

putAll in interface WritableLongObjMap<T>

See Also:

WritableLongObjMap.putAll(long[], Object[])

putAll

public void putAll(long[] keys,
          T[] values)

Description copied from interface: WritableLongObjMap

Specified by:

putAll in interface WritableLongObjMap<T>

putAllKeys

public void putAllKeys(LongIterable keys,
              java.lang.Iterable<T> values)

Description copied from interface: WritableLongObjMap

Puts all keys in the map, taking as many values as needed; when no values are available, uses default value. (1, 2, 3, 4), null -> ([1, 0], [2, 0], [3, 0], [4, 0]) (1, 2, 3, 4), () -> ([1, 0], [2, 0], [3, 0], [4, 0]) (1, 2, 3, 4), (1, 2) -> ([1, 1], [2, 2], [3, 0], [4, 0]) (1, 2, 3, 4), (1, 2, 3, 4) -> ([1, 1], [2, 2], [3, 3], [4, 4]) (1, 2, 3, 4), (1, 2, 3, 4, 6, 7, 8) -> ([1, 1], [2, 2], [3, 3], [4, 4])

removeAll

public void removeAll(long... keys)

Specified by:

removeAll in interface WritableLongObjMap<T>

removeAll

public void removeAll(LongIterable keys)

Specified by:

removeAll in interface WritableLongObjMap<T>

toString

public java.lang.StringBuilder toString(java.lang.StringBuilder builder)

toString

public final java.lang.String toString()

Overrides:

toString in class java.lang.Object

toTableString

public java.lang.String toTableString()

equals

public boolean equals(java.lang.Object o)

Description copied from interface: LongObjMap

Compares the specified object with this map for equality. Returns true if and only if the specified object is also a LongObjMap and both objects contain exactly the same key-value pairs, regardless of their order

Specified by:

equals in interface LongObjMap<T>

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Specified by:

hashCode in interface LongObjMap<T>

Overrides:

hashCode in class java.lang.Object

Returns:

A hash code of elements stored in the map. The hash code is defined as a sum of hash codes of keys and values stored within the map. Because addition is commutative, this ensures that different order of elements in a map does not affect the hash code.
