All Implemented Interfaces:

Comparable, Copyable, DataUnit, FieldListener, LiveData, MutableTreeNode, TreeNode

Direct Known Subclasses:

ZipEntry

public class ZipEntry

extends LiveTreeNode

This class represents a member of a zip archive. ZipFile and ZipInputStream will give you instances of this class as information about the members in an archive. On the other hand ZipOutputStream needs an instance of this class to create a new member.

Field Summary

static int	DEFLATED Compression method.
SubString	myFileName
static int	STORED Compression method.

Constructor Detail

ZipEntry

public ZipEntry(String name)

Creates a zip entry with the given name.

Parameters:

name - the name. May include directory components separated by '/'.

ZipEntry

public ZipEntry(ZipEntry e)

Creates a copy of the given zip entry.

Parameters:

e - the entry to copy.

Method Detail

getName

public String getName()

Returns the entry name. The path components in the entry are always separated by slashes ('/').

Specified by:

getName in interface LiveData

Overrides:

getName in class LiveObject

setTime

public void setTime(Time t)

Sets the time of last modification of the entry.

getTime

public Time getTime(Time t)

Gets the time of last modification of the entry.

Returns:

the time of last modification of the entry, or -1 if unknown.

setSize

public void setSize(int size)

Sets the size of the uncompressed data.

Throws:

IllegalArgumentException - if size is not in 0..0xffffffffL

getSize

public int getSize()

Gets the size of the uncompressed data.

Returns:

the size or -1 if unknown.

setCompressedSize

public void setCompressedSize(int csize)

Sets the size of the compressed data.

Throws:

IllegalArgumentException - if size is not in 0..0xffffffffL

getCompressedSize

public int getCompressedSize()

Gets the size of the compressed data.

Returns:

the size or -1 if unknown.

setCrc

public void setCrc(int crc)

Sets the crc of the uncompressed data.

Throws:

IllegalArgumentException - if crc is not in 0..0xffffffffL

getCrc

public long getCrc()

Gets the crc of the uncompressed data.

Returns:

the crc (lower 32 bits) or -1 if unknown.

setMethod

public boolean setMethod(int method)

Sets the compression method. Only DEFLATED and STORED are supported.

Throws:

IllegalArgumentException - if method is not supported.

See Also:

ZipOutputStream.DEFLATED, ZipOutputStream.STORED

getMethod

public int getMethod()

Gets the compression method.

Returns:

the compression method or -1 if unknown.
