Constructor Details

CompositeGuardingDynamicLinker

public CompositeGuardingDynamicLinker(Iterable<? extends GuardingDynamicLinker> linkers)

Creates a new composite linker.

Parameters:: linkers - a list of component linkers.
Throws:: NullPointerException - if linkers or any of its elements are null.

Method Details

getGuardedInvocation

public GuardedInvocation getGuardedInvocation(LinkRequest linkRequest, LinkerServices linkerServices) throws Exception

Delegates the call to its component linkers. The first non-null value returned from a component linker is returned. If no component linker returns a non-null invocation, null is returned.

Specified by:: getGuardedInvocation in interface GuardingDynamicLinker
Parameters:: linkRequest - the object describing the request for linking a particular invocation; linkerServices - linker services
Returns:: the first non-null return value from a component linker, or null if none of the components returned a non-null.
Throws:: Exception - if the operation fails for whatever reason
