false) [explicit]

Member Function Documentation
FileCollection * zipios::DirectoryCollection::clone () const [virtual]
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.
Returns
A heap allocated copy of the object this method is called for.
Implements zipios::FileCollection.
Definition at line 114 of file dircoll.cpp.
void zipios::DirectoryCollection::close () [virtual]
Closes the FileCollection.
Implements zipios::FileCollection.
Definition at line 33 of file dircoll.cpp.
ConstEntries zipios::DirectoryCollection::entries () const [virtual]
Returns a vector of const pointers to the entries in the FileCollection.
Returns
a ConstEntries containing the entries of the FileCollection.
Exceptions
InvalidStateException Thrown if the collection is invalid.
Reimplemented from zipios::FileCollection.
Definition at line 38 of file dircoll.cpp.
ConstEntryPointer zipios::DirectoryCollection::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
name A string containing the name of the entry to get.
matchpath Speficy MATCH, if the path should match as well, specify IGNORE, if the path should be
ignored.
Returns
A ConstEntryPointer to the found entry. The returned pointer equals zero if no entry is found.
Exceptions
InvalidStateException Thrown if the collection is invalid.
Reimplemented from zipios::FileCollection.
Definition at line 49 of file dircoll.cpp.
istream * zipios::DirectoryCollection::getInputStream (const ConstEntryPointer & entry) [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
entry A ConstEntryPointer to the FileEntry to get an istream to.
Returns
an open istream for the specified entry. The istream is allocated on heap and it is the users
responsibility to delete it when he is done with it.
Exceptions
InvalidStateException Thrown if the collection is invalid.
Implements zipios::FileCollection.
Definition at line 68 of file dircoll.cpp.
istream * zipios::DirectoryCollection::getInputStream (const string & entry_name, MatchPath matchpath =
MATCH) [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
matchpath Speficy MATCH, if the path should match as well, specify IGNORE, if the path should be
ignored.
Returns
an open istream for the specified entry. The istream is allocated on heap and it is the users
responsibility to delete it when he is done with it.
Exceptions
InvalidStateException Thrown if the collection is invalid.
