Enum ExpressionFactory.UnaryOperator

java.lang.Object
  java.lang.Enum<ExpressionFactory.UnaryOperator>
      org.glassfish.pfl.dynamic.codegen.impl.ExpressionFactory.UnaryOperator

All Implemented Interfaces:

Serializable, Comparable<ExpressionFactory.UnaryOperator>

Enclosing class:

ExpressionFactory

public static enum ExpressionFactory.UnaryOperator
extends Enum<ExpressionFactory.UnaryOperator>

Operators that apply to a single expression. The only unary operator that we support at present is ! (NOT) because this is very useful in constructing boolean expressions for while loops and conditionals.

Method Detail

values

public static ExpressionFactory.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 (ExpressionFactory.UnaryOperator c : ExpressionFactory.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 ExpressionFactory.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
