virtual void zipios::FileCollection::close () [pure virtual]¶
Closes the FileCollection.
Implemented in zipios::CollectionCollection, zipios::ZipFile, and zipios::DirectoryCollection.
ConstEntries zipios::FileCollection::entries () const [virtual]¶
Returns a vector of const pointers to the entries in the FileCollection.
Returns:
Exceptions:
Reimplemented in zipios::CollectionCollection, and zipios::DirectoryCollection.
Definition at line 17 of file fcoll.cpp.
ConstEntryPointer zipios::FileCollection::getEntry (const string & name, MatchPath matchpath = MATCH) const [virtual]¶
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.
Parameters:
matchpath Speficy MATCH, if the path should match as well, specify IGNORE, if the path should be ignored.
Returns:
Exceptions:
Reimplemented in zipios::CollectionCollection, and zipios::DirectoryCollection.
Definition at line 34 of file fcoll.cpp.
virtual istream* zipios::FileCollection::getInputStream (const ConstEntryPointer & entry) [pure virtual]¶
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.
Parameters:
Returns:
Exceptions:
Implemented in zipios::CollectionCollection, zipios::ZipFile, and zipios::DirectoryCollection.
virtual istream* zipios::FileCollection::getInputStream (const string & entry_name, MatchPath matchpath = MATCH) [pure virtual]¶
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.
Parameters:
Returns:
Exceptions:
Implemented in zipios::CollectionCollection, zipios::ZipFile, and zipios::DirectoryCollection.
