Enum Quantifier

java.lang.Object

java.lang.Enum<Quantifier>

spoon.pattern.Quantifier

All Implemented Interfaces:

Serializable, Comparable<Quantifier>

public enum Quantifier
extends Enum<Quantifier>

Defines a matching strategy for pattern parameters, default is GREEDY.

Enum Constant Summary

Enum Constants

Enum Constant	Description
GREEDY	Force the matcher to read in, or eat, the entire input prior to attempting the next match (default).
POSSESSIVE	The possessive quantifier always eats the entire input string, trying once (and only once) for a match.
RELUCTANT	The reluctant quantifier takes the opposite approach: It start at the beginning of the input, then reluctantly eats one character at a time looking for a match.

Method Summary

Modifier and Type	Method	Description
static Quantifier	valueOf(String name)	Returns the enum constant of this type with the specified name.
static Quantifier[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

GREEDY

public static final Quantifier GREEDY

Force the matcher to read in, or eat, the entire input prior to attempting the next match (default). If the next match attempt (the entire input) fails, the matcher backs off the input by one and tries again, repeating the process until a match is found or there are no more elements left to back off from.

RELUCTANT

public static final Quantifier RELUCTANT

The reluctant quantifier takes the opposite approach: It start at the beginning of the input, then reluctantly eats one character at a time looking for a match. The last thing it tries is the entire input.

POSSESSIVE

public static final Quantifier POSSESSIVE

The possessive quantifier always eats the entire input string, trying once (and only once) for a match. Unlike the greedy quantifiers, possessive quantifiers never back off, even if doing so would allow the overall match to succeed.

Method Detail

values

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

Returns:

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

valueOf

public static Quantifier 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
