Method Detail

values

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

Returns:

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

valueOf

public static Expression.Operation valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

fromString

public static Expression.Operation fromString(java.lang.String operationType)

negate

public Expression.Operation negate()

Returns the operation used when this is negated.

flipLR

public Expression.Operation flipLR()

Returns the equivalent operation when the left and right operands are exchanged.
