ByteArrayWindow

ByteArrayWindow(PackFile pack,
                long o,
                byte[] b)

Method Detail

copy

protected int copy(int p,
                   byte[] b,
                   int o,
                   int n)

Copy bytes from the window to a caller supplied buffer.

Specified by:

copy in class ByteWindow

Parameters:

p - offset within the window to start copying from.

b - destination buffer to copy into.

o - offset within dstbuf to start copying into.

n - number of bytes to copy. This value may exceed the number of bytes remaining in the window starting at offset pos.

Returns:

number of bytes actually copied; this may be less than cnt if cnt exceeded the number of bytes available.

setInput

protected int setInput(int pos,
                       java.util.zip.Inflater inf)
                throws java.util.zip.DataFormatException

Set the input

Specified by:

setInput in class ByteWindow

Parameters:

pos - position

inf - an Inflater object.

Returns:

size of the byte window

Throws:

java.util.zip.DataFormatException - if any.

crc32

void crc32(java.util.zip.CRC32 out,
           long pos,
           int cnt)

write

void write(PackOutputStream out,
           long pos,
           int cnt)
    throws java.io.IOException

Specified by:

write in class ByteWindow

Throws:

java.io.IOException

check

void check(java.util.zip.Inflater inf,
           byte[] tmp,
           long pos,
           int cnt)
    throws java.util.zip.DataFormatException

Throws:

java.util.zip.DataFormatException
