Constructor & Destructor Documentation

zipios::ZipFile::ZipFile ( ) [inline]

Default constructor.

Definition at line 37 of file zipfile.h.

zipios::ZipFile::ZipFile ( const string & name,

int s_off = 0,

int e_off = 0 ) [explicit]

Constructor.
Opens the zip file name. If the zip "file" is embedded in a file that contains other data, e.g. a binary program, the offset of the zip file start and end must be specified.
Parameters:

name The filename of the zip file to open.

s_off Offset relative to the start of the file, that indicates the beginning of the zip file.

e_off Offset relative to the end of the file, that indicates the end of the zip file. The offset is a positive number, even though the offset is towards the beginning of the file.

Exceptions:

FColException Thrown if the specified file name is not a valid zip archive.

IOException Thrown if an I/O problem is encountered, while the directory of the specified zip archive is being read.

Definition at line 30 of file zipfile.cpp.

zipios::ZipFile::~ZipFile ( ) [virtual]

Destructor.

Definition at line 46 of file zipfile.cpp.

Member Function Documentation

FileCollection * zipios::ZipFile::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.

Reimplemented from zipios::FileCollection.
Definition at line 41 of file zipfile.cpp.

void zipios::ZipFile::close ( ) [virtual]

Closes the FileCollection.

Reimplemented from zipios::FileCollection.
Definition at line 50 of file zipfile.cpp.

istream * zipios::ZipFile::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.

Reimplemented from zipios::FileCollection.
Definition at line 61 of file zipfile.cpp.

istream * zipios::ZipFile::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.

Reimplemented from zipios::FileCollection.
Definition at line 55 of file zipfile.cpp.

ZipFile zipios::ZipFile::openEmbeddedZipFile ( const string & name ) [static]

Opens a Zip archive embedded in another file, by writing the zip archive to the end of the file followed by the start offset of the zip file.
The offset must be written in zip-file byte-order (little endian). The program appendzip, which is part of the Zipios++ distribution can be used to append a Zip archive to a file, e.g. a binary program.
Exceptions:

FColException Thrown if the specified file name is not a valid zip archive.

IOException Thrown if an I/O problem is encountered, while the directory of the specified zip archive is being read.
