Method Details

match

public boolean match(A x)

Description copied from class: Pattern

Attempt to match this pattern against a given object. If the class of this pattern imposes a specific order on matches, the first one is chosen. The pattern is activated on success, but deactivated on failure.

Specified by:

match in class Pattern<A>

Returns:

true if the matching is successful, false if it fails. Which Pattern.Variables are bound by a successful match is class-specific.

matchAgain

public boolean matchAgain()

Description copied from class: Pattern

Attempt to re-match this pattern against a previously matched object. If the class of this pattern imposes a specific order on matches, they are chosen in that order, beginning with the second one. The pattern is activated on success, but deactivated on failure. The behaviour of this method is unspecified if the pattern is currently deactivated.

Patterns classes that do not overwrite this method guarantee

Overrides:

matchAgain in class Pattern<A>

Returns:

true if the matching is successful, false if it fails. Which Pattern.Variables are bound by a successful match is class-specific. The default implementation always returns false.
