Inherited Constants

From interface java.util.jar.Pack200.Packer

String	CLASS_ATTRIBUTE_PFX	When concatenated with a class attribute name, indicates the format of that attribute, using the layout language specified in the JSR 200 specification.
String	CODE_ATTRIBUTE_PFX	When concatenated with a code attribute name, indicates the format of that attribute.
String	DEFLATE_HINT	If this property is set to `TRUE` or `FALSE`, the packer will set the deflation hint accordingly in the output archive, and will not transmit the individual deflation hints of archive elements.
String	EFFORT	If this property is set to a single decimal digit, the packer will use the indicated amount of effort in compressing the archive.
String	ERROR	The string "error", a possible value for certain properties.
String	FALSE	The string "false", a possible value for certain properties.
String	FIELD_ATTRIBUTE_PFX	When concatenated with a field attribute name, indicates the format of that attribute.
String	KEEP	The string "keep", a possible value for certain properties.
String	KEEP_FILE_ORDER	If this property is set to `TRUE`, the packer will transmit all elements in their original order within the source archive.
String	LATEST	The string "latest", a possible value for certain properties.
String	METHOD_ATTRIBUTE_PFX	When concatenated with a method attribute name, indicates the format of that attribute.
String	MODIFICATION_TIME	If this property is set to the special string `LATEST`, the packer will attempt to determine the latest modification time, among all the available entries in the original archive or the latest modification time of all the available entries in each segment.
String	PASS	The string "pass", a possible value for certain properties.
String	PASS_FILE_PFX	Indicates that a file should be passed through bytewise, with no compression.
String	PROGRESS	The unpacker's progress as a percentage, as periodically updated by the unpacker.
String	SEGMENT_LIMIT	This property is a numeral giving the estimated target size N (in bytes) of each archive segment.
String	STRIP	The string "strip", a possible value for certain properties.
String	TRUE	The string "true", a possible value for certain properties.
String	UNKNOWN_ATTRIBUTE	Indicates the action to take when a class-file containing an unknown attribute is encountered.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Constructors

public PackerImpl ()

Constructs a Packer object and sets the initial state of the packer engines.

Public Methods

public void addPropertyChangeListener (PropertyChangeListener listener)

Register a listener for changes to options.

Parameters

listener	An object to be invoked when a property is changed.

public void pack (JarFile in, OutputStream out)

Takes a JarFile and converts into a pack-stream.

Closes its input but not its output. (Pack200 archives are appendable.)

Parameters

in	a JarFile
out	an OutputStream

Throws

IOException	if an error is encountered.

public void pack (JarInputStream in, OutputStream out)

Takes a JarInputStream and converts into a pack-stream.

Closes its input but not its output. (Pack200 archives are appendable.)

The modification time and deflation hint attributes are not available, for the jar-manifest file and the directory containing the file.

Parameters

in	a JarInputStream
out	an OutputStream

Throws

IOException	if an error is encountered.

public SortedMap properties ()

Get the set of options for the pack and unpack engines.

Returns

A sorted association of option key strings to option values.

public void removePropertyChangeListener (PropertyChangeListener listener)

Remove a listener for the PropertyChange event.

Parameters

listener	The PropertyChange listener to be removed.
