Constructor Summary

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)

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.
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.
