Class DataReader

java.lang.Object
  micromod.DataReader

public class DataReader

extends java.lang.Object

The DataReader contains methods to convert data on an implementation of DataInput into a more useful format. DataInput is only used to read bytes and arrays of bytes to aid portability.

Field Summary

protected static int	CONVERT_BUFFER_SIZE
protected byte[]	convertBuffer
protected java.io.DataInput	input

Constructor Summary

DataReader(java.io.DataInput input)
Constructor

Method Summary

static int	readInt32(java.io.DataInput input) Read a signed 32 bit integer.
static short	readSigned16Bit(java.io.DataInput input) Read a single signed 16 bit word.
void	readSigned16BitArray(short[] array, int offset, int length) Read length 16 bit signed, big endian words from the DataInput device into the specified array.
static byte	readSigned8Bit(java.io.DataInput input) Read a single signed byte.
static void	readSigned8BitArray(java.io.DataInput input, byte[] array, int offset, int length) Read length 8 bit signed words from the DataInput device into the specified array.
static java.lang.String	readText(java.io.DataInput input, int count) Simple method to read ASCII text and convert nulls to spaces.
static int	readUnsigned16Bit(java.io.DataInput input) Read a single unsigned 16 bit word.
static byte	readUnsigned7Bit(java.io.DataInput input) Read a positive number from a byte between 0 and 127.
static int	readUnsigned8Bit(java.io.DataInput input) Read a single unsigned byte.
