Enum Constant Detail

UNDEFINED

public static final Predicate.TYPE UNDEFINED

type of predicate is not yet set

CONTROL

public static final Predicate.TYPE CONTROL

predicate is a control construct. This type of predicate could be created only during initialization.

BUILD_IN

public static final Predicate.TYPE BUILD_IN

predicate is a build in. This type of predicate could be created only during initialization.

USER_DEFINED

public static final Predicate.TYPE USER_DEFINED

predicate is a user defined predicate.

EXTERNAL

public static final Predicate.TYPE EXTERNAL

predicate is a user defined predicate defined in Java Class.

Method Detail

values

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

Returns:

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

valueOf

public static Predicate.TYPE 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
