Method Detail

containsKey

public boolean containsKey(java.lang.Object key)

Description copied from interface: Function

Returns true if this function contains a mapping for the specified key.

Note that for some kind of functions (e.g., hashes) this method will always return true. This default implementation, in particular, always return true.

Specified by:

containsKey in interface Function<K,java.lang.Byte>

Parameters:

key - the key.

Returns:

true if this function associates a value to key.

getByte

public byte getByte(java.lang.Object key)

Description copied from interface: Object2ByteFunction

Returns the value to which the given key is mapped.

Specified by:

getByte in interface Object2ByteFunction<K>

Parameters:

key - the key.

Returns:

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