readLine

public String readLine()
                throws 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 DataInput

Throws:

IOException

readPrimitiveArray

public int readPrimitiveArray(Object o)
                       throws 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:

IOException

primitiveArrayRecurse

protected int primitiveArrayRecurse(Object o)
                             throws IOException

Throws:

IOException

readBooleanArray

protected int readBooleanArray(boolean[] b)
                        throws IOException

Throws:

IOException

readShortArray

protected int readShortArray(short[] s)
                      throws IOException

Throws:

IOException

readCharArray

protected int readCharArray(char[] c)
                     throws IOException

Throws:

IOException

readIntArray

protected int readIntArray(int[] i)
                    throws IOException

Throws:

IOException

readLongArray

protected int readLongArray(long[] l)
                     throws IOException

Throws:

IOException

readFloatArray

protected int readFloatArray(float[] f)
                      throws IOException

Throws:

IOException

readDoubleArray

protected int readDoubleArray(double[] d)
                       throws IOException

Throws:

IOException

primitiveEOFThrower

protected void primitiveEOFThrower()
                            throws EOFException

Throws:

EOFException

printStatus

public void printStatus()

toString

public String toString()

main

public static void main(String[] args)
                 throws 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:

Exception
