Method Details

addTo

public long addTo(float k,

Adds an increment to value currently associated with a key.

Note that this method respects the default return value semantics: when called with a key that does not currently appears in the map, the key will be associated with the default return value plus the given increment.

Parameters:

k - the key.

incr - the increment.

Returns:

the old value, or the default return value if no value was present for the given key.

put

public long put(float k,

Adds a pair to the map (optional operation).

Specified by:

put in interface Float2LongFunction

Parameters:
