Method Details

apply

public R apply(T t)

Specified by:

apply in interface Function<T,R>

call

public R call(Object arg)

Description copied from class: Closure

Invokes the closure with given argument(s), returning any value if applicable.

Overrides:

call in class Closure<R>

Parameters:

arg - could be a single value or a List of values

Returns:

The value if applicable or null if there is no return statement in the closure.

call

public R call(Object... args)

Description copied from class: Closure

Invokes the closure with given argument(s), returning any value if applicable.

Overrides:

call in class Closure<R>

Returns:

The value if applicable or null if there is no return statement in the closure.

additionalReferences

protected Object[] additionalReferences()

Exposes the wrapped Function, which the call methods dispatch to but which is held outside the owner/delegate/thisObject references the cycle check walks by default. Only Closure-valued links are followed, so a plain Function contributes nothing.

Overrides:

additionalReferences in class Closure<R>

Returns:

the additional closures reached when this one is invoked; never null
