Class BitCounterUncompressed

java.lang.Object

ucar.nc2.iosp.bufr.BitCounterUncompressed

All Implemented Interfaces:

BitCounter

public class BitCounterUncompressed
extends java.lang.Object
implements BitCounter

Counts the size of nested tables, for uncompressed messages. A top-level BitCounterUncompressed counts bits for one row = obs = dataset. obs = new BitCounterUncompressed(root, 1, 0);

Constructor Detail

BitCounterUncompressed

public BitCounterUncompressed(DataDescriptor parent,
                              int nrows,
                              int replicationCountSize)

This counts the size of an array of Structures or Sequences, ie Structure(n)

Parameters:

parent - is a structure or a sequence - so has subKeys

nrows - numbers of rows in the table, equals 1 for top level

replicationCountSize - number of bits taken up by the count variable (non-zero only for sequences)

Method Detail

setBitOffset

public void setBitOffset(DataDescriptor dkey)

getOffset

public int getOffset(DataDescriptor dkey)

makeNested

public BitCounterUncompressed makeNested(DataDescriptor subKey,
                                         int n,
                                         int row,
                                         int replicationCountSize)

Track nested Tables.

Parameters:

subKey - subKey is a structure or a sequence - so itself has subKeys

n - numbers of rows in the nested table

row - which row in the parent Table this belongs to

replicationCountSize - number of bits taken up by the count (non-zero for sequences)

Returns:

nested ReplicationCounter

getNested

public BitCounterUncompressed[] getNested(DataDescriptor subKey)

getCountBits

public int getCountBits()

getNumberRows

public int getNumberRows()

Specified by:

getNumberRows in interface BitCounter

getStartBit

public int getStartBit(int row)

toString

public void toString(java.util.Formatter f,
                     Indent indent)
