readLine

public java.lang.String readLine()
                          throws java.io.IOException

Deprecated.

This routine uses the deprecated DataInputStream.readLine() method. However, we really want to simulate the behavior of that method so that's what we used.

Specified by:

readLine in interface java.io.DataInput

Throws:

java.io.IOException

readPrimitiveArray

public int readPrimitiveArray(java.lang.Object o)
                       throws java.io.IOException

This routine provides efficient reading of arrays of any primitive type. It is an error to invoke this method with an object that is not an array of some primitive type. Note that there is no corresponding capability to writePrimitiveArray in BufferedDataOutputStream to read in an array of Strings.

Parameters:

o - The object to be read. It must be an array of a primitive type, or an array of Object's.

Throws:

java.io.IOException

primitiveArrayRecurse

protected int primitiveArrayRecurse(java.lang.Object o)
                             throws java.io.IOException

protected int readBooleanArray(boolean[] b)
                        throws java.io.IOException

Throws:

java.io.IOException

readShortArray

protected int readShortArray(short[] s)
                      throws java.io.IOException

Throws:

java.io.IOException

readCharArray

protected int readCharArray(char[] c)
                     throws java.io.IOException

Throws:

java.io.IOException

readIntArray

protected int readIntArray(int[] i)
                    throws java.io.IOException

Throws:

java.io.IOException

readLongArray

protected int readLongArray(long[] l)
                     throws java.io.IOException

Throws:

java.io.IOException

readFloatArray

protected int readFloatArray(float[] f)
                      throws java.io.IOException

Throws:

java.io.IOException

readDoubleArray

protected int readDoubleArray(double[] d)
                       throws java.io.IOException

Throws:

java.io.IOException

primitiveEOFThrower

protected void primitiveEOFThrower()
                            throws java.io.EOFException

Throws:

java.io.EOFException

printStatus

public void printStatus()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

main

public static void main(java.lang.String[] args)
                 throws java.lang.Exception

This method is used to test and time the buffered data methods. Note that the BufferedDataOutputStream.main simply calls this method which is used to test both classes in conjunction.

Throws:

java.lang.Exception
