Interface XDRDataInput

All Superinterfaces:

java.io.DataInput

All Known Implementing Classes:

XDRInputStream, XDRRandomAccessFile

public interface XDRDataInput

extends java.io.DataInput

An interface implemented by input streams that support XDR. The XDR format is almost identical to the normal Java DataInput format, except that items are padded to 4 byte boundaries, and strings are normally stored in ASCII format.

Method Summary

void	pad() Skips appropriate amount to bring stream to 4-byte boundary.
double[]	readDoubleArray(double[] buffer) Reads a double array.
float[]	readFloatArray(float[] buffer) Reads a float array.
int[]	readIntArray(int[] buffer) Reads an integer array.
java.lang.String	readString() Read a String.
java.lang.String	readString(int l) Reads a String of length l bytes, and skips appropriate amount to bring stream to 4-byte boundary.

Method Detail

readString

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

Read a String. Assumes int length proceeds String. Throws an exception if string length > 32767 to protect against bad data exhausting memory.

readString

public java.lang.String readString(int l)
                            throws java.io.IOException

Reads a String of length l bytes, and skips appropriate amount to bring stream to 4-byte boundary.

readIntArray

public int[] readIntArray(int[] buffer)
                   throws java.io.IOException

Reads an integer array. Assumes int length proceeds array. Throws an exception if array length > 32767 to protect against bad data exhausting memory. If buffer is not null, and is large enough to hold array, it is filled and returned, otherwise a new array is allocated and returned.

readDoubleArray

public double[] readDoubleArray(double[] buffer)
                         throws java.io.IOException

Reads a double array. Assumes int length proceeds array. Throws an exception if array length > 32767 to protect against bad data exhausting memory. If buffer is not null, and is large enough to hold array, it is filled and returned, otherwise a new array is allocated and returned.

readFloatArray

public float[] readFloatArray(float[] buffer)
                       throws java.io.IOException

Reads a float array. Assumes int length proceeds array. Throws an exception if array length > 32767 to protect against bad data exhausting memory. If buffer is not null, and is large enough to hold array, it is filled and returned, otherwise a new array is allocated and returned.

pad

public void pad()
         throws java.io.IOException

Skips appropriate amount to bring stream to 4-byte boundary.
