Detailed Description

FileCollection is an abstract baseclass that represents a collection of files.

The specializations of FileCollection represents different origins of file collections, such as directories, simple filename lists and compressed archives.

Member Function Documentation

FileCollection * zipios::FileCollection::clone ( ) const [pure 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.

Reimplemented in zipios::CollectionCollection, zipios::DirectoryCollection, and zipios::ZipFile.

void zipios::FileCollection::close ( ) [pure virtual]

Closes the FileCollection.

Reimplemented in zipios::CollectionCollection, zipios::DirectoryCollection, and zipios::ZipFile.

ConstEntries zipios::FileCollection::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 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:

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 in zipios::CollectionCollection, and zipios::DirectoryCollection.
Definition at line 34 of file fcoll.cpp.

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:

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.

Reimplemented in zipios::CollectionCollection, zipios::DirectoryCollection, and zipios::ZipFile.

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:

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.

Reimplemented in zipios::CollectionCollection, zipios::DirectoryCollection, and zipios::ZipFile.

string zipios::FileCollection::getName ( ) const [virtual]

Returns the name of the FileCollection.

Returns:
the name of the FileCollection.
Exceptions:

InvalidStateException Thrown if the collection is invalid.

Definition at line 50 of file fcoll.cpp.

bool zipios::FileCollection::isValid ( ) const [inline]

The member function returns true if the collection is valid.

Returns:
true if the collection is valid.

Definition at line 93 of file fcoll.h.

const FileCollection & zipios::FileCollection::operator= ( const FileCollection & src ) [inline]

Copy assignment operator.

Definition at line 125 of file fcoll.h.

int zipios::FileCollection::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 in zipios::CollectionCollection, and zipios::DirectoryCollection.
Definition at line 57 of file fcoll.cpp.
