AbstractRandomAccessArray

public AbstractRandomAccessArray(int offset,
                                 int length,
                                 int byteOrder)

AbstractRandomAccessArray

public AbstractRandomAccessArray(int offset,
                                 int length,
                                 int byteOrder,
                                 BufferPosition fp)

Method Detail

setByteOrder

public void setByteOrder(int byteOrder)

Description copied from interface: ISeekable

set byte order

Specified by:

setByteOrder in interface ISeekable

Overrides:

setByteOrder in class AbstractRandomAccessInput

createShiftBE

protected abstract int[] createShiftBE()

createShiftLE

protected abstract int[] createShiftLE()

getBytesPerUnit

protected abstract int getBytesPerUnit()

getAndMask

protected abstract int getAndMask()

getFilePointer

public long getFilePointer()

Description copied from interface: ISeekable

Since this is an interface and is not restricted to files, "getFilePointer" is wrong name for this method. But I leaved it so for easier porting from RandomAccessFile

Returns:

current cursor position

length

public long length()

Description copied from interface: ISeekable

get length of data

Returns:

data length (in bytes)

seek

public void seek(long offset)
          throws java.io.IOException

Description copied from interface: ISeekable

set current cursor position to specified offset

Parameters:

offset - new cursor position

Throws:

java.io.IOException

skip

public long skip(long n)
          throws java.io.IOException

Throws:

java.io.IOException

close

public void close()
           throws java.io.IOException

Throws:

java.io.IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws java.io.IOException

Throws:

java.io.IOException

readBE

protected abstract void readBE(int srcOffset,
                               int count,
                               byte[] dest,
                               int off)

readLE

protected abstract void readLE(int srcOffset,
                               int count,
