org.apache.derby.iapi.sql.depend.DependencyManager.clearDependencies()
Erases all of the dependencies the dependent has, be they valid or invalid, of any dependency type. This action is usually performed as the first step in revalidating a dependent; it first erases all the old dependencies, then revalidates itself generating a list of new dependencies, and then marks itself valid if all its new dependencies are valid.
There might be a future want to clear all dependencies for a particular provider, e.g. when destroying the provider. However, at present, they are assumed to stick around and it is the responsibility of the dependent to erase them when revalidating against the new version of the provider.
clearDependencies will delete dependencies if they are stored; the delete is finalized at the next commit. @param lcc Compiler state @param d the dependent @exception StandardException Thrown on failure
