With a CollectionCollection the user can use multiple FileCollections transparently, making it easy for a program to keep some of its files in a zip archive and others stored in ordinary files. CollectionCollection can be used to create a simple virtual filesystem, where all collections are mounted in /. If more than one collection contain a file with the same path only the one in the first added collection will be accessible.

|
Adds the collection pointed to by collection. The CollectionCollection will call delete on the pointer when it is destructed, so the caller should make absolutely sure to only pass in a collection created with new and be sure to leave it alone after adding it. If the collection is not added false is returned and the caller remains responsible for the collection pointed to by collection.

Create a heap allocated clone of the object this method is called for. The caller is responsible for deallocating the clone when he is done with it.

A protected getEntry member function, that not only finds an entry that match the name, if such an entry exists in the collection, it also returns, which collection it was found in.

|
Returns a ConstEntryPointer to a FileEntry object for the entry with the specified name. To ignore the path part of the filename in search of a match, specify FileCollection::IGNORE as the second argument.
Reimplemented from zipios::FileCollection. Definition at line 58 of file collcoll.cpp. |
|
Returns a pointer to an opened istream for the specified entry name. It is the callers responsibility to delete the stream when he is done with it. Returns 0, if there is no entry with the specified name in the FileCollection.

Returns a pointer to an opened istream for the specified FileEntry. It is the callers responsibility to delete the stream when he is done with it. Returns 0, if there is no such FileEntry in the FileCollection.
