Enum Constant Summary

Enum Constants

Enum Constant	Description
BNOT	Bitwise complement, ~, flipping every bit of an integral operand.
NEG	Arithmetic negation, -, applied to a single numeric operand.
NOT	Logical negation, !, applying to a boolean operand.
POS	Unary plus, +, which leaves the value alone but still promotes a narrower operand to int.
POST_DEC	Postfix decrement, x--, which yields the operand's value from before the decrement.
POST_INC	Postfix increment, x++, which yields the operand's value from before the increment.
PRE_DEC	Prefix decrement, --x, which yields the already-decremented value.
PRE_INC	Prefix increment, ++x, which yields the already-incremented value.

Method Summary

Modifier and Type	Method	Description

Enum Constant Detail

NEG

public static final UnaryOperator NEG

Arithmetic negation, -, applied to a single numeric operand.

POS

public static final UnaryOperator POS

Unary plus, +, which leaves the value alone but still promotes a narrower operand to int.

BNOT

public static final UnaryOperator BNOT

Bitwise complement, ~, flipping every bit of an integral operand.

NOT

public static final UnaryOperator NOT

Logical negation, !, applying to a boolean operand.

PRE_INC

public static final UnaryOperator PRE_INC

Prefix increment, ++x, which yields the already-incremented value.

PRE_DEC

public static final UnaryOperator PRE_DEC

Prefix decrement, --x, which yields the already-decremented value.

POST_INC

public static final UnaryOperator POST_INC

Postfix increment, x++, which yields the operand's value from before the increment.

POST_DEC

public static final UnaryOperator POST_DEC

Postfix decrement, x--, which yields the operand's value from before the decrement.

Method Detail

values

public static UnaryOperator[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (UnaryOperator c : UnaryOperator.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static UnaryOperator valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

getSymbol

public String getSymbol()

Returns:

the symbol

isPrefix

public boolean isPrefix()

Returns:

true if the symbol is written before its operand

isPostfix

public boolean isPostfix()

Returns:

true if the symbol is written after its operand

isIncDec

public boolean isIncDec()

Returns:

true for the four increment and decrement operators

toString

public String toString()

Overrides:
