Constructor Summary
ZipEntry(String name)
Creates a new zip entry with the specified name.
ZipEntry(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.
protected ZipEntry()
Method Summary
voidaddExtraField(ZipExtraField ze)
Adds an extra fields - replacing an already present extra field of the same type.
Objectclone()
Overwrite clone
byte[]getCentralDirectoryExtra()
Retrieves the extra data for the central directory.
longgetCompressedSize()
Override to make this class work in JDK 1.1 like a 1.2 class.
longgetExternalAttributes()
Retrieves the external file attributes.
ZipExtraField[]getExtraFields()
Retrieves extra fields.
intgetInternalAttributes()
Retrieves the internal file attributes.
longgetLastModificationTime()
byte[]getLocalFileDataExtra()
Retrieves the extra data for the local file data.
StringgetName()
intgetPlatform()
Platform specification to put into the "version made by" part of the central file header.
intgetUnixMode()
Unix permission.
booleanisDirectory()
voidremoveExtraField(ZipShort type)
Remove an extra fields.
voidsetComprSize(long size)
Make this class work in JDK 1.1 like a 1.2 class.
voidsetExternalAttributes(long value)
Sets the external file attributes.
voidsetExtra(byte[] extra)
Throws an Exception if extra data cannot be parsed into extra fields.
protected voidsetExtra()
Unfortunately java.util.zip.ZipOutputStream 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.
voidsetExtraFields(ZipExtraField[] fields)
Replaces all currently attached extra fields with the new array.
voidsetInternalAttributes(int value)
Sets the internal file attributes.
protected voidsetName(String name)
protected voidsetPlatform(int platform)
voidsetUnixMode(int mode)
Sets Unix permissions in a way that is understood by Info-Zip's unzip command.
