Class CpioHeader

public class CpioHeader extends Object

This class provides a means to read file content from the compressed CPIO stream that is the body of an RPM distributable. Iterative calls to to read header will result in a header description being returned which includes a count of how many bytes to read from the channel for the file content.

isLast

public boolean isLast()

Test to see if this is the last header, and is therefore the end of the archive. Uses the CPIO magic trailer value to denote the last header of the stream.

pad

protected String pad(CharSequence sequence, int length)

read

public int read(ReadableByteChannel channel, int total)

readChars

protected CharSequence readChars(CharBuffer buffer, int length)

readEight

protected int readEight(CharBuffer buffer)

readSix

protected CharSequence readSix(CharBuffer buffer)

setFileSize

public void setFileSize(int filesize)

setFlags

public void setFlags(int flags)

setGname

public void setGname(String gname)

setInode

public void setInode(int inode)

setLast

public void setLast()

setMtime

public void setMtime(long mtime)

setName

public void setName(String name)

setPermissions

public void setPermissions(int permissions)

setType

public void setType(int type)

setUname

public void setUname(String uname)

skip

protected int skip(ReadableByteChannel channel, int total)

skip

public int skip(WritableByteChannel channel, int total)

toString

public String toString()

write

public int write(WritableByteChannel channel, int total)

Writed the content for the CPIO header, including the name immediately following. The name data is rounded to the nearest 2 byte boundary as CPIO requires by appending a null when needed.

writeEight

protected ByteBuffer writeEight(int data)

writeSix

protected ByteBuffer writeSix(CharSequence data)
