Method Details

match

public boolean match(A target)

Description copied from class: Pattern

Attempts 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.

Specified by:

match in class Pattern<A>

Parameters:

target - the object to match against

Returns:

true if the matching is successful, false if it fails. Which Variables are bound by a successful or failed match depends.

See Also:

• Pattern.binds(Variable)
• Pattern.preserves(Variable, boolean)

matchAgain

public boolean matchAgain()

Description copied from class: Unary

Attempts 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 behaviour of this method is unspecified if the last matching attempt of this pattern has not been successful.

Patterns classes that do not override this method are deterministic. Pattern classes that overwrite this method to provide additional matches should also override Pattern.isDeterministic(). The default implementation delegates to Unary.body.

Overrides:

matchAgain in class Unary<B,A>

Returns:

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

• Pattern.preserves(Variable, boolean)

isRange

public boolean isRange(B transformed)
