Enum Constant Detail

TERMINAL

public static final MatcherType TERMINAL

Terminal: a matcher which does not need another matcher to operate

This is equivalent to a terminal rule in formal grammars.

ACTION

public static final MatcherType ACTION

Action

Only used by ActionMatcher.

COMPOSITE

public static final MatcherType COMPOSITE

Composite

A matcher which delegates to other matchers to determine the success of its operation. Such a matcher will also contain logic to determine whether the whole match succeeds.

PREDICATE

public static final MatcherType PREDICATE

Predicate

Indicates a matcher which delegates to other rules but will never advance into the input text.

Method Detail

values

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

Returns:

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

valueOf

public static MatcherType 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
