applyAsInt
public int applyAsInt(K operand)
Description copied from interface:Object2ByteFunction
- Specified by:
applyAsInt
in interfaceObject2ByteFunction<K>
- Specified by:
applyAsInt
in interfacejava.util.function.ToIntFunction<K>
-
apply
@Deprecated public java.lang.Byte apply(K key)
Deprecated.Please use the corresponding type-specific method instead.This is equivalent to callingFunction.get(Object)
.- Specified by:
apply
in interfaceFunction<K,java.lang.Byte>
- Specified by:
apply
in interfacejava.util.function.Function<K,java.lang.Byte>
- 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.
-
defaultReturnValue
public byte defaultReturnValue()
Description copied from interface:Object2ByteFunction
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 interfaceObject2ByteFunction<K>
- Returns:
- the current default return value.
-
defaultReturnValue
public void defaultReturnValue(byte defRetValue)
Description copied from interface:Object2ByteFunction
Sets the default return value (optional operation). This value must be returned by type-specific versions ofget()
,put()
andremove()
to denote that the map does not contain the specified key. It must be 0/false
/null
by default.- Specified by:
defaultReturnValue
in interfaceObject2ByteFunction<K>
- Parameters:
defRetValue
- the new default return value.- See Also:
Object2ByteFunction.defaultReturnValue()
-
containsKey
public boolean containsKey(java.lang.Object k)
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 interfaceFunction<K,java.lang.Byte>
- Parameters:
k
- the key.- Returns:
- true if this function associates a value to
key
. - See Also:
Map.containsKey(Object)
-
put
public byte put(K k, byte v)
Description copied from interface:Object2ByteFunction
Adds a pair to the map (optional operation).- Specified by:
put
in interfaceObject2ByteFunction<K>
- 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)
-
getByte
public byte getByte(java.lang.Object k)
Description copied from interface:Object2ByteFunction
Returns the value to which the given key is mapped.- Specified by:
getByte
in interfaceObject2ByteFunction<K>
- 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)
-
removeByte
public byte removeByte(java.lang.Object k)
Description copied from interface:Object2ByteFunction
Removes the mapping with the given key (optional operation).- Specified by:
removeByte
in interfaceObject2ByteFunction<K>
- Parameters:
k
- the key.- Returns:
- 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).
-
put
@Deprecated public java.lang.Byte put(K k, java.lang.Byte v)
Deprecated.Please use the corresponding type-specific method instead.Associates the specified value with the specified key in this function (optional operation).
-
get
@Deprecated public java.lang.Byte get(java.lang.Object k)
Deprecated.Please use the corresponding type-specific method instead.Returns the value associated by this function to the specified key.
-
remove
@Deprecated public java.lang.Byte remove(java.lang.Object k)
Deprecated.Please use the corresponding type-specific method instead.Removes this key and the associated value from this function if it is present (optional operation).
