Method Detail

isAffectedByAny

boolean isAffectedByAny(java.util.Collection<IResourceDescription.Delta> deltas,
                        IResourceDescription candidate,
                        IResourceDescriptions context)
                 throws java.lang.IllegalArgumentException

Batch operation to check whether a description is affected by any given delta in the given context. Implementations may perform any optimizations to return false whenever possible, e.g. check the deltas against the visible containers.

Parameters:

deltas - List of deltas to check. May not be null. In contrast to IResourceDescription.Manager.isAffected(Collection, IResourceDescription, IResourceDescriptions) callers of this method are expected to pass in all deltas, even if they don't have changed IEObjectDescriptions

candidate - The description to check. May not be null.

context - The current context of the batch operation. May not be null.

Returns:

whether the candidate is affected by any of the given changes.

Throws:

java.lang.IllegalArgumentException - if this manager is not responsible for the given candidate.
