Interfaces
| Pack200.Packer |
The packer engine applies various transformations to the input JAR file,
making the pack stream highly compressible by a compressor such as
gzip or zip. |
| Pack200.Unpacker |
The unpacker engine converts the packed stream to a JAR file. |
Classes
| Attributes |
The Attributes class maps Manifest attribute names to associated string
values. |
| Attributes.Name |
The Attributes.Name class represents an attribute name stored in
this Map. |
| JarEntry |
This class is used to represent a JAR file entry. |
| JarFile |
The JarFile class is used to read the contents of a jar file
from any file that can be opened with java.io.RandomAccessFile. |
| JarInputStream |
The JarInputStream class is used to read the contents of
a JAR file from any input stream. |
| JarOutputStream |
The JarOutputStream class is used to write the contents
of a JAR file to any output stream. |
| Manifest |
The Manifest class is used to maintain Manifest entry names and their
associated Attributes. |
| Pack200 |
Transforms a JAR file to or from a packed stream in Pack200 format. |
Exceptions
| JarException |
Signals that an error of some sort has occurred while reading from
or writing to a JAR file. |
