JarOutputStream

open class JarOutputStream : ZipOutputStream

kotlin.Any
↳	java.io.OutputStream
	↳	java.io.FilterOutputStream
		↳	java.util.zip.DeflaterOutputStream
			↳	java.util.zip.ZipOutputStream
				↳	java.util.jar.JarOutputStream

The JarOutputStream class is used to write the contents of a JAR file to any output stream. It extends the class java.util.zip.ZipOutputStream with support for writing an optional Manifest entry. The Manifest can be used to specify meta-information about the JAR file and its entries.

Inherited constants

From class ZipOutputStream

Int

DEFLATED

Compression method for compressed (DEFLATED) entries.

Int

STORED

Compression method for uncompressed (STORED) entries.

Public constructors
`JarOutputStream(out: OutputStream!)` Creates a new `JarOutputStream` with no manifest.
`JarOutputStream(out: OutputStream!, man: Manifest!)` Creates a new `JarOutputStream` with the specified `Manifest`.

Public methods
open Unit	`putNextEntry(ze: ZipEntry!)` Begins writing a new JAR file entry and positions the stream to the start of the entry data.

Inherited functions

From class ZipOutputStream

`Unit`	`close()` Closes the ZIP output stream as well as the stream being filtered.
`Unit`	`closeEntry()` Closes the current ZIP entry and positions the stream for writing the next entry.
`Unit`	`finish()` 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.
`Unit`	`setComment(comment: String!)` Sets the ZIP file comment.
`Unit`	`setLevel(level: Int)` Sets the compression level for subsequent entries which are DEFLATED. The default setting is DEFAULT_COMPRESSION.
`Unit`	`setMethod(method: Int)` 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.
`Unit`	`write(b: ByteArray!, off: Int, len: Int)` Writes an array of bytes to the current ZIP entry data. This method will block until all the bytes are written.

From class DeflaterOutputStream

Unit

deflate()

Writes next block of compressed data to the output stream.

Unit

flush()

Flushes the compressed output stream. If syncFlush is true when this compressed output stream is constructed, this method first flushes the underlying compressor with the flush mode Deflater.SYNC_FLUSH to force all pending data to be flushed out to the output stream and then flushes the output stream. Otherwise this method only flushes the output stream without flushing the compressor.

Unit

write(b: Int)

Writes a byte to the compressed output stream. This method will block until the byte can be written.

From class OutputStream

OutputStream!

nullOutputStream()

Returns a new OutputStream which discards all bytes. The returned stream is initially open. The stream is closed by calling the close() method. Subsequent calls to close() have no effect.

While the stream is open, the write(int), write(byte[]), and write(byte[], int, int) methods do nothing. After the stream has been closed, these methods all throw IOException.

The flush() method does nothing.

From class FilterOutputStream

Unit

write(b: ByteArray!)

Writes b.length bytes to this output stream.

The write method of FilterOutputStream calls its write method of three arguments with the arguments b, 0, and b.length.

Note that this method does not call the one-argument write method of its underlying output stream with the single argument b.

Inherited properties

From class DeflaterOutputStream

ByteArray!

buf

Output buffer for writing compressed data.

Deflater!

def

Compressor for this stream.

From class FilterOutputStream

OutputStream!

out

The underlying output stream to be filtered.

Parameters
`out`	OutputStream!: the actual output stream
`man`	Manifest!: the optional `Manifest`

Parameters
`e`	the ZIP entry to be written
`ze`	ZipEntry!: the ZIP/JAR entry to be written

Exceptions
`java.util.zip.ZipException`	if a ZIP format error has occurred
`java.io.IOException`	if an I/O error has occurred
`java.util.zip.ZipException`	if a ZIP error has occurred
`java.io.IOException`	if an I/O error has occurred
