mark all dependencies on the named provider as invalid. When invalidation types show up, this will use the default invalidation type. The dependencies will still exist once they are marked invalid; clearDependencies should be used to remove dependencies that a dependent has or provider gives.
Implementations of this can take a little time, but are not really expected to recompile things against any changes made to the provider that caused the invalidation. The dependency system makes no guarantees about the state of the provider -- implementations can call this before or after actually changing the provider to its new state.
Implementations should throw DependencyStatementException if the invalidation should be disallowed. @param p the provider @param action The action causing the invalidate @param lcc The LanguageConnectionContext @exception StandardException thrown if unable to make it invalid
