Method Details

setKeysAndValues

protected void setKeysAndValues(long[] keysAndValues)

Specified by:

setKeysAndValues in class HashMapBase

put

public long put(long key,
 long value)

Description copied from interface: NullableLongLongMap

Add a mapping from key to value. Return the old value of key.

Specified by:

put in interface NullableLongLongMap

Parameters:

key - the key to add

value - the value to add

Returns:

the old value of key (or NullableLongLongMap.defaultReturnValue()} if there was no mapping)

putIfAbsent

public long putIfAbsent(long key,
 long value)

Description copied from interface: NullableLongLongMap

Add a mapping from key to value, if one does not already exist. Return the old value of key (or NullableLongLongMap.defaultReturnValue()) if one does not exist.

Specified by:

putIfAbsent in interface NullableLongLongMap

Parameters:

key - the key to add

value - the value to add

Returns:

the old value of key (or NullableLongLongMap.defaultReturnValue()} if there was no mapping)

get

public long get(long key)

Description copied from interface: NullableLongLongMap

Gets the value associated with key. Returns NullableLongLongMap.defaultReturnValue()} if no mapping exists.

Specified by:

Parameters:

key - the key to get

Returns:

the value of the key (or NullableLongLongMap.defaultReturnValue())

remove

public long remove(long key)

Description copied from interface: NullableLongLongMap

Remove a mapping for a key. Return the removed value of key (or NullableLongLongMap.defaultReturnValue()) if one does not exist.

Specified by:

remove in interface NullableLongLongMap

Parameters:

key - the key to add

Returns:

the removed value of (or NullableLongLongMap.defaultReturnValue()} if there was no mapping)
