Method Detail

put

public long put(byte key,
                long value)
Adds a pair to the map.

Parameters:
key - the key.
value - the value.
Returns:
the old value, or the default return value if no value was present for the given key.
See Also:
Map.put(Object,Object)

get

public long get(byte key)
Returns the value to which the given key is mapped.

Parameters:
key - the key.
Returns:
the corresponding value, or the default return value if no value was present for the given key.
See Also:
Map.get(Object)

remove

public long remove(byte key)
Removes the mapping with the given key.

Parameters:
key -
Returns:
the old value, or the default return value if no value was present for the given key.
See Also:
Map.remove(Object)

containsKey

public boolean containsKey(byte key)
See Also:
Map.containsKey(Object)

containsValue

public boolean containsValue(long value)
See Also:
Map.containsValue(Object)

setDefRetValue

public void setDefRetValue(long rv)
Deprecated. As of fastutil 2.0, replaced by defaultReturnValue().

Sets the default return value. This value is returned by get(), put() and remove() to denote that the map does not contain the specified key. It is 0/false/null by default.

Parameters:
rv - the new default return value.
See Also:
getDefRetValue(), defaultReturnValue()

getDefRetValue

public long getDefRetValue()
Deprecated. As of fastutil 2.0, replaced by defaultReturnValue().

Gets the default return value.

Returns:
the current default return value.
See Also:
defaultReturnValue()

defaultReturnValue

public void defaultReturnValue(long rv)
Sets the default return value. This value is returned by get(), put() and remove() to denote that the map does not contain the specified key. It is 0/false/null by default.

Parameters:
rv - the new default return value.
See Also:
defaultReturnValue()

defaultReturnValue

public long defaultReturnValue()
Gets the default return value.

Returns:
the current default return value.
