IntegerField

• java.lang.Object

Fields Summary
private int	_value
private final int	_offset

Constructors Summary
public IntegerField(int offset) construct the IntegerField with its offset into its containing byte array param offset of the field within its byte array exception ArrayIndexOutOfBoundsException if the offset is negative if (offset < 0) { throw new ArrayIndexOutOfBoundsException("negative offset"); } _offset = offset;
public IntegerField(int offset, int value) construct the IntegerField with its offset into its containing byte array and initialize its value param offset of the field within its byte array param value the initial value exception ArrayIndexOutOfBoundsException if the offset is negative this(offset); set(value);
public IntegerField(int offset, byte[] data) Construct the IntegerField with its offset into its containing byte array and initialize its value from its byte array param offset of the field within its byte array param data the byte array to read the value from exception ArrayIndexOutOfBoundsException if the offset is not within the range of 0..(data.length - 1) this(offset); readFromBytes(data);
public IntegerField(int offset, int value, byte[] data) construct the IntegerField with its offset into its containing byte array, initialize its value, and write the value to a byte array param offset of the field within its byte array param value the initial value param data the byte array to write the value to exception ArrayIndexOutOfBoundsException if the offset is negative or too large this(offset); set(value, data);

Methods Summary
public int	get() get the IntegerField's current value return current value return _value;
public void	readFromBytes(byte[] data) set the value from its offset into an array of bytes param data the byte array from which the value is to be read exception ArrayIndexOutOfBoundsException if the offset is too large _value = LittleEndian.getInt(data, _offset);
public void	readFromStream(java.io.InputStream stream) set the value from an InputStream param stream the InputStream from which the value is to be read exception BufferUnderrunException if there is not enough data available from the InputStream exception IOException if an IOException is thrown from reading the InputStream _value = LittleEndian.readInt(stream);
public void	set(int value) set the IntegerField's current value param value to be set _value = value;
public void	set(int value, byte[] data) set the IntegerField's current value and write it to a byte array param value to be set param data the byte array to write the value to exception ArrayIndexOutOfBoundsException if the offset is too large _value = value; writeToBytes(data);
public java.lang.String	toString() return the value as a String return the value as a String return String.valueOf(_value);
public void	writeToBytes(byte[] data) write the value out to an array of bytes at the appropriate offset param data the array of bytes to which the value is to be written exception ArrayIndexOutOfBoundsException if the offset is too large LittleEndian.putInt(data, _offset, _value);
