Method Summary

Modifier and TypeMethod and Description
public byte[]

Returns:

the data
getCentralDirectoryData()

Implements org.apache.commons.compress.archivers.zip.ZipExtraField.getCentralDirectoryData.

The actual data to put central directory - without Header-ID or length specifier.
public ZipShort

Returns:

0
getCentralDirectoryLength()

Implements org.apache.commons.compress.archivers.zip.ZipExtraField.getCentralDirectoryLength.

Length of the extra field in the central directory - without Header-ID or length specifier.
public ZipShort

Returns:

the header id
getHeaderId()

Implements org.apache.commons.compress.archivers.zip.ZipExtraField.getHeaderId.

The Header-ID.
public static JarMarker

Returns:

the DEFAULT jarmaker.
getInstance()

Since JarMarker is stateless we can always use the same instance.

public byte[]

Returns:

the data
getLocalFileDataData()

Implements org.apache.commons.compress.archivers.zip.ZipExtraField.getLocalFileDataData.

The actual data to put into local file data - without Header-ID or length specifier.
public ZipShort

Returns:

0
getLocalFileDataLength()

Implements org.apache.commons.compress.archivers.zip.ZipExtraField.getLocalFileDataLength.

Length of the extra field in the local file data - without Header-ID or length specifier.
public void
parseFromCentralDirectoryData(final byte[]
the buffer to read data from
buffer, final int
offset into buffer to read data

Implements org.apache.commons.compress.archivers.zip.ZipExtraField.parseFromCentralDirectoryData.

Doesn't do anything special since this class always uses the same data in central directory and local file data.
public void

data, final int
the start offset
offset, final int
the number of bytes in the array from offset
length)

Implements org.apache.commons.compress.archivers.zip.ZipExtraField.parseFromLocalFileData.

Populate data from this array as if it was in local file data.
