Method Detail

getPattern

public String getPattern()

Returns:

The value of the pattern attribute

eval

public <OUTPUT_TYPE extends QueryTarget> Set<OUTPUT_TYPE> eval(QueryEvaluator<NODE_TYPE> evaluator,
                                                               QueryEnvironment<NODE_TYPE> env)
                                                        throws QueryException

Description copied from class: QueryExpression

Evaluates this query in the specified environment, and returns a (possibly-immutable) set of targets.

Failures resulting from evaluation of an ill-formed query cause QueryException to be thrown.

Throws:

QueryException

traverse

public void traverse(com.facebook.buck.query.QueryExpression.Visitor<NODE_TYPE> visitor)

Description copied from class: QueryExpression

Accepts and applies the given visitor.

Specified by:

traverse in class QueryExpression<NODE_TYPE>

toString

public String toString()

Description copied from class: QueryExpression

Returns this query expression pretty-printed.

Specified by:

toString in class QueryExpression<NODE_TYPE>

equals

public boolean equals(@Nullable
                      Object another)

This instance is equal to all instances of TargetLiteral that have equal attribute values.

Overrides:

equals in class Object

Returns:

true if this is equal to another instance

hashCode

public int hashCode()

Overrides:

hashCode in class Object

of

public static <T> TargetLiteral<T> of(String pattern)

Construct a new immutable TargetLiteral instance.

Parameters:

pattern - The value for the pattern attribute

Returns:

An immutable TargetLiteral instance
