Description copied from interface: DependencySelector

Applies exclusions to the specified dependency.

Specified by:

selectDependency in interface DependencySelector

Parameters:

dependency - The dependency to filter, must not be null.

Returns:

false if the dependency should be excluded from the children of the current node, true otherwise.

deriveChildSelector

public DependencySelector deriveChildSelector(DependencyCollectionContext context)

Description copied from interface: DependencySelector

Specified by:

deriveChildSelector in interface DependencySelector

Parameters:

context - The dependency collection context, must not be null.

Returns:

The dependency filter for the target node, must not be null.
