zipios::DirectoryCollection::DirectoryCollection (const string & path, bool
recursive = true, bool load_now = false) [explicit]
Constructor.
Parameters:
path A directory path name. If the name is not a valid directory
the created DirectoryCollection will be invalid.
load_now Load directory into memory now. Otherwise it will be done
when it is first needed.

Member Function Documentation
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.
Implements zipios::FileCollection.
Definition at line 76 of file dircoll.cpp.
int zipios::DirectoryCollection::size () const [virtual]
Returns the number of entries in the FileCollection.
Returns:
the number of entries in the FileCollection.
Exceptions:
InvalidStateException Thrown if the collection is invalid.
Reimplemented from zipios::FileCollection.
Definition at line 106 of file dircoll.cpp.
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.
