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.

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.

Public constructors

JarOutputStream

Added in API level 1

JarOutputStream(out: OutputStream!)

Creates a new JarOutputStream with no manifest.

Parameters
out	OutputStream!: the actual output stream

Exceptions
java.io.IOException	if an I/O error has occurred

JarOutputStream

Added in API level 1

JarOutputStream(
    out: OutputStream!, 
    man: Manifest!)

Creates a new JarOutputStream with the specified Manifest. The manifest is written as the first entry to the output stream.

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

Exceptions
java.io.IOException	if an I/O error has occurred

Public methods

putNextEntry

Added in API level 1

open fun putNextEntry(ze: ZipEntry!): Unit

Begins writing a new JAR file entry and positions the stream to the start of the entry data. This method will also close any previous entry. The default compression method will be used if no compression method was specified for the entry. The current time will be used if the entry has no set modification time.

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

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