All known Subclasses: java.util.jar.JarOutputStream,
| ZipOutputStream | | public class ZipOutputStream extends DeflaterOutputStream implements ZipConstants(Code) | | This class implements an output stream filter for writing files in the
ZIP file format. Includes support for both compressed and uncompressed
entries.

| Field Summary | |
| final public static int | DEFLATED
Compression method for compressed (DEFLATED) entries. | | final public static int | STORED
Compression method for uncompressed (STORED) entries. |
| Method Summary | |
| public void | close()
Closes the ZIP output stream as well as the stream being filtered. | | public void | closeEntry()
Closes the current ZIP entry and positions the stream for writing
the next entry. | | public void | finish()
Finishes writing the contents of the ZIP output stream without closing
the underlying stream. | | static int | getUTF8Length(String s)
| | public void | putNextEntry(ZipEntry e)
Begins writing a new ZIP file entry and positions the stream to the
start of the entry data. | | public void | setComment(String comment)
Sets the ZIP file comment. | | public void | setLevel(int level)
Sets the compression level for subsequent entries which are DEFLATED. | | public void | setMethod(int method)
Sets the default compression method for subsequent entries. | | public synchronized void | write(byte[] b, int off, int len)
Writes an array of bytes to the current ZIP entry data. |
| DEFLATED | | final public static int DEFLATED(Code) | | Compression method for compressed (DEFLATED) entries.
|
| STORED | | final public static int STORED(Code) | | Compression method for uncompressed (STORED) entries.
|
| ZipOutputStream | | public ZipOutputStream(OutputStream out)(Code) | | Creates a new ZIP output stream.
Parameters:
out - the actual output stream |
| close | | public void close() throws IOException(Code) | | Closes the ZIP output stream as well as the stream being filtered.
exception:
ZipException - if a ZIP file error has occurred
exception:
IOException - if an I/O error has occurred |
| closeEntry | | public void closeEntry() throws IOException(Code) | | Closes the current ZIP entry and positions the stream for writing
the next entry.
exception:
ZipException - if a ZIP format error has occurred
exception:
IOException - if an I/O error has occurred |
| finish | | public void finish() throws IOException(Code) | | Finishes writing the contents of the ZIP output stream without closing
the underlying stream. Use this method when applying multiple filters
in succession to the same output stream.
exception:
ZipException - if a ZIP file error has occurred
exception:
IOException - if an I/O exception has occurred |
| putNextEntry | | public void putNextEntry(ZipEntry e) throws IOException(Code) | | Begins writing a new ZIP file entry and positions the stream to the
start of the entry data. Closes the current entry if still active.
The default compression method will be used if no compression method
was specified for the entry, and the current time will be used if
the entry has no set modification time.
Parameters:
e - the ZIP entry to be written
exception:
ZipException - if a ZIP format error has occurred
exception:
IOException - if an I/O error has occurred |
| setComment | | public void setComment(String comment)(Code) | | Sets the ZIP file comment.
Parameters:
comment - the comment string
exception:
IllegalArgumentException - if the length of the specifiedZIP file comment is greater than 0xFFFF bytes |
| setLevel | | public void setLevel(int level)(Code) | | Sets the compression level for subsequent entries which are DEFLATED.
The default setting is DEFAULT_COMPRESSION.
Parameters:
level - the compression level (0-9)
exception:
IllegalArgumentException - if the compression level is invalid |
| setMethod | | public void setMethod(int method)(Code) | | Sets the default compression method for subsequent entries. This
default will be used whenever the compression method is not specified
for an individual ZIP file entry, and is initially set to DEFLATED.
Parameters:
method - the default compression method
exception:
IllegalArgumentException - if the specified compression methodis invalid |
| write | | public synchronized void write(byte[] b, int off, int len) throws IOException(Code) | | Writes an array of bytes to the current ZIP entry data. This method
will block until all the bytes are written.
Parameters:
b - the data to be written
Parameters:
off - the start offset in the data
Parameters:
len - the number of bytes that are written
exception:
ZipException - if a ZIP file error has occurred
exception:
IOException - if an I/O error has occurred |
