Constructor Summary

protected	ZipEntry()
	ZipEntry(java.lang.String name) Creates a new zip entry with the specified name.
	ZipEntry(java.util.zip.ZipEntry entry) Creates a new zip entry with fields taken from the specified zip entry.
	ZipEntry(ZipEntry entry) Creates a new zip entry with fields taken from the specified zip entry.

Method Summary

void	addExtraField(ZipExtraField ze) Adds an extra fields - replacing an already present extra field of the same type.
java.lang.Object	clone() Overwrite clone
byte[]	getCentralDirectoryExtra() Retrieves the extra data for the central directory.
long	getCompressedSize() Override to make this class work in JDK 1.1 like a 1.2 class.
long	getExternalAttributes() Retrieves the external file attributes.
ZipExtraField[]	getExtraFields() Retrieves extra fields.
int	getInternalAttributes() Retrieves the internal file attributes.
byte[]	getLocalFileDataExtra() Retrieves the extra data for the local file data.
java.lang.String	getName()

int	getUnixMode() Unix permission.
boolean	isDirectory()
void	removeExtraField(ZipShort type) Remove an extra fields.
void	setComprSize(long size) Make this class work in JDK 1.1 like a 1.2 class.
void	setExternalAttributes(long value) Sets the external file attributes.
protected void	setExtra() Unfortunately java.util.zip.ZipOutputStream seems to access the extra data directly, so overriding getExtra doesn't help - we need to modify super's data directly.
void	setExtra(byte[] extra) Throws an Exception if extra data cannot be parsed into extra fields.
void	setExtraFields(ZipExtraField[] fields) Replaces all currently attached extra fields with the new array.
void	setInternalAttributes(int value) Sets the internal file attributes.
