## Constructor & Destructor Documentation

### zipios::ZipOutputStreambuf::ZipOutputStreambuf (streambuf \* outbuf, bool del\_outbuf = `false`)` [explicit]`

**ZipOutputStreambuf** constructor. A newly constructed **ZipOutputStreambuf** is not ready to accept data, **putNextEntry()** must be invoked first.

**Parameters:**

*outbuf* the streambuf to use for input. \
 *del\_outbuf* if true is specified outbuf will be deleted, when the **ZipOutputStreambuf** is destructed.

Definition at line 20 of file zipoutputstreambuf.cpp.

### zipios::ZipOutputStreambuf::~ZipOutputStreambuf ()` [virtual]`

Destructor.

Definition at line 56 of file zipoutputstreambuf.cpp.

## Member Function Documentation

### void zipios::ZipOutputStreambuf::close ()

Calls finish.

Definition at line 41 of file zipoutputstreambuf.cpp.

### void zipios::ZipOutputStreambuf::closeEntry ()

Closes the current entry, and positions the stream read pointer at the beginning of the next entry (if there is one).

Definition at line 30 of file zipoutputstreambuf.cpp.

### void zipios::ZipOutputStreambuf::finish ()

Closes the current entry (if one is open), then writes the Zip Central Directory Structure closing the **ZipOutputStream**. The output stream that the zip archive is being written to is not closed.

Definition at line 46 of file zipoutputstreambuf.cpp.

### void zipios::ZipOutputStreambuf::putNextEntry (const ZipCDirEntry & entry)

Begins writing the next entry. Opens the next entry in the zip archive and returns a const pointer to a **FileEntry** object for the entry.

**Returns:**

a const **FileEntry** \* containing information about the (now) current entry.

Definition at line 61 of file zipoutputstreambuf.cpp.

### void zipios::ZipOutputStreambuf::setComment (const string & comment)

Sets the global comment for the Zip archive.

Definition at line 83 of file zipoutputstreambuf.cpp.

### void zipios::ZipOutputStreambuf::setLevel (int level)

Sets the compression level to be used for subsequent entries.

Definition at line 88 of file zipoutputstreambuf.cpp.

### void zipios::ZipOutputStreambuf::setMethod (StorageMethod method)

Sets the compression method to be used. only STORED and DEFLATED are supported.

Definition at line 93 of file zipoutputstreambuf.cpp.
