Method Detail

name

String name()

Gets a name for the node type.

Returns:

a name

matches

boolean matches(Node node)

Returns if the passed node matches the type

Parameters:

node - the node to test

Returns:

true if the node has the same type

cast

T cast(Node node)

Casts the given Node to the type defined by the NodeType.

An IllegalArgumentException is thrown if the node to cast does not match the type.

Parameters:

node - the node to cast

Returns:

the casted node

Throws:

IllegalArgumentException - if the node to cast does not match the type

tryCast

default Optional<T> tryCast(Node node)

Attempts to cast the given Node to the type defined by the NodeType.

Returns an empty optional if the node to cast does not match the type.

Parameters:

node - the node to cast

Returns:

an optional, possibly containing a casted node

predicate

default Predicate<Node> predicate()

Returns a Predicate, returning whether a Node matches this type.

Returns:

a predicate for the matches(Node) method.

predicate

default Predicate<Node> predicate(Predicate<? super T> and)

Returns a Predicate, returning whether a Node matches this type, and passes the given and Predicate.

Parameters:

and - a predicate to AND with the result of the type match check

Returns:

a matching predicate, ANDed with the given predicate parameter
