- All Implemented Interfaces:
java.io.Serializable
,java.lang.Comparable<ExpressionFactory.UnaryOperator>
- Enclosing class:
- ExpressionFactory
public static enum ExpressionFactory.UnaryOperator extends java.lang.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.

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(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 namejava.lang.NullPointerException
- if the argument is null
