Enum Constant Summary

Enum Constants

Enum Constant	Description
ABS	This expression is the absolute value of the result from the inner expression.
CAST	This expression is the result of the inner expression casted to a different type
NEGATE	This expression is the negation of the inner expression.
SIGN	The result of this expression is 0 if the result of the inner expression is 0, 1 of the inner returned something positive and -1 if the inner returned something negative.
SQRT	The result of this expression is the positive square root of the result of the inner expression.

Enum Constant Detail

ABS

public static final UnaryExpression.Operator ABS

This expression is the absolute value of the result from the inner expression. That is, the negation sign is ignored, returning only positive values.

CAST

public static final UnaryExpression.Operator CAST

This expression is the result of the inner expression casted to a different type

NEGATE

public static final UnaryExpression.Operator NEGATE

This expression is the negation of the inner expression. That is, the negation sign is flipped.

SIGN

public static final UnaryExpression.Operator SIGN

The result of this expression is 0 if the result of the inner expression is 0, 1 of the inner returned something positive and -1 if the inner returned something negative.

SQRT

public static final UnaryExpression.Operator SQRT

The result of this expression is the positive square root of the result of the inner expression.

Method Detail

values

public static UnaryExpression.Operator[] 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 (UnaryExpression.Operator c : UnaryExpression.Operator.values())
    System.out.println(c);

Returns:

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

valueOf

public static UnaryExpression.Operator 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
