Method Detail

values

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

Returns:

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

valueOf

public static BinaryOperator 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

isTrue

public static boolean isTrue(SassListItem item)

evalInternal

protected LexicalUnitImpl evalInternal(LexicalUnitImpl leftValue,
                                       LexicalUnitImpl rightValue)

Evaluates an arithmetic expression. The parameters leftValue and rightValue must not be list-valued.

eval(SassListItem, SassListItem)

eval

public SassListItem eval(SassListItem leftOperand,
                         SassListItem rightOperand)

Returns the result of applying the operator to the operands. The default implementation verifies that the operands are simple LexicalUnitImpl instances and calls evalInternal() on them. Either eval() or evalInternal() can be overridden depending on the allowed operand types for the operator.
