Method Details

applyAsDouble

@Deprecated
public double applyAsDouble(int operand)

Deprecated.

Please use the corresponding type-specific method instead.

Specified by:

applyAsDouble in interface Byte2FloatFunction

Specified by:

applyAsDouble in interface IntToDoubleFunction

apply

@Deprecated
public Float apply(Byte key)

Deprecated.

Please use the corresponding type-specific method instead.

This is equivalent to calling Function.get(Object).

Specified by:

apply in interface Function<Byte,Float>

Specified by:

apply in interface Function<Byte,Float>

Parameters:

key -

Returns:

See Also:

• Function.apply(Object)
• Function.get(Object)

size

public int size()

Description copied from interface: Function

Returns the intended number of keys in this function, or -1 if no such number exists.

Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible. This default implementation, in particular, returns -1.

Specified by:

size in interface Function<Byte,Float>

Returns:

the intended number of keys in this function, or -1 if that number is not available.

defaultReturnValue

public float defaultReturnValue()

Description copied from interface: Byte2FloatFunction

Gets the default return value.

This default implementation just return the default null value of the type (null for objects, 0 for scalars, false for Booleans).

Specified by:

defaultReturnValue in interface Byte2FloatFunction

Returns:

the current default return value.

defaultReturnValue

public void defaultReturnValue(float defRetValue)

Description copied from interface: Byte2FloatFunction

Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.

Specified by:

defaultReturnValue in interface Byte2FloatFunction

Parameters:

defRetValue - the new default return value.

See Also:

• Byte2FloatFunction.defaultReturnValue()

containsKey

public boolean containsKey(byte k)

Description copied from interface: Byte2FloatFunction

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. In particular, this default implementation always returns true.

Specified by:

containsKey in interface Byte2FloatFunction

Parameters:

k - the key.

Returns:

true if this function associates a value to key.

See Also:

• Function.containsKey(Object)

containsKey

@Deprecated
public boolean containsKey(Object k)

Deprecated.

Description copied from interface: Byte2FloatFunction

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 Byte2FloatFunction

Specified by:

containsKey in interface Function<Byte,Float>

Parameters:

k - the key.

Returns:

true if this function associates a value to key.

See Also:

• Map.containsKey(Object)

put

public float put(byte k,
 float v)

Description copied from interface: Byte2FloatFunction

Adds a pair to the map (optional operation).

Specified by:

put in interface Byte2FloatFunction

Parameters:

k - the key.

v - the value.

Returns:

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

See Also:

• Function.put(Object,Object)

get

public float get(byte k)

Description copied from interface: Byte2FloatFunction

Returns the value to which the given key is mapped.

Specified by:

get in interface Byte2FloatFunction

Parameters:

k - the key.

Returns:

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

See Also:

• Function.get(Object)

getOrDefault

public float getOrDefault(byte k,
 float defaultValue)

Description copied from interface: Byte2FloatFunction

Returns the value associated by this function to the specified key, or give the specified value if not present.

Specified by:

getOrDefault in interface Byte2FloatFunction

Parameters:

k - the key.

defaultValue - the value to return if not present.

Returns:

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

See Also:

• Function.getOrDefault(Object, Object)

remove

public float remove(byte k)

Description copied from interface: Byte2FloatFunction

Removes the mapping with the given key (optional operation).

Specified by:

remove in interface Byte2FloatFunction

Parameters:

k - the key.

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

See Also:

• Function.remove(Object)

clear

public void clear()

Description copied from interface: Function

Removes all associations from this function (optional operation).

Specified by:
