Constructor Details

Derived

public Derived(org.dmfs.jems2.FragileFunction<? super Original,? extends Derivate,Exception> derivationFunction,
 Resource<? extends Original> delegate)

Derivate of an existing Resource. The resource is derived by applying the given FragileFunction on the original Resource value.

Use this constructor when the derived Resource does not need a separate clean-up procedure.

Derived

public Derived(org.dmfs.jems2.FragileFunction<? super Original,? extends Derivate,Exception> derivationFunction,
 Resource<? extends Original> delegate,
 org.dmfs.jems2.FragileProcedure<Derivate,Exception> cleanUp)

Derivate of an existing Resource. The resource is derived by applying the given FragileFunction on the original Resource value.

The given clean-up procedure is executed when the resource is no longer needed.

Note that, at present, the original resource might be closed before this one is cleaned-up. This might change in future versions.
