Description copied from class: CharMatcher

Determines a true or false value for the given character.

Specified by:

matches in class CharMatcher

toString

public java.lang.String toString()

Description copied from class: CharMatcher

Returns a string representation of this CharMatcher, such as CharMatcher.or(WHITESPACE, JAVA_DIGIT).

Overrides:

toString in class CharMatcher

equals

public boolean equals(@Nullable
                      java.lang.Object other)

Description copied from interface: Predicate

Indicates whether another object is equal to this predicate.

Most implementations will have no reason to override the behavior of Object.equals(java.lang.Object). However, an implementation may also choose to return true whenever object is a Predicate that it considers interchangeable with this one. "Interchangeable" typically means that this.apply(t) == that.apply(t) for all t of type T). Note that a false result from this method does not imply that the predicates are known not to be interchangeable.

Specified by:

equals in interface Predicate<java.lang.Character>

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object
