Interface XDRDataInput

All Superinterfaces:

DataInput

All Known Implementing Classes:

XDRInputStream, XDRRandomAccessFile

public interface XDRDataInput

extends 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 Detail

pad

public void pad()
         throws IOException

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

Throws:

IOException

readDoubleArray

public double[] readDoubleArray(double[] buffer)
                         throws 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.

Throws:

IOException

readFloatArray

public float[] readFloatArray(float[] buffer)
                       throws 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.

Throws:

IOException

readIntArray

public int[] readIntArray(int[] buffer)
                   throws 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.

Throws:

IOException

readString

public String readString()
                  throws IOException

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

Throws:

IOException

readString

public String readString(int l)
                  throws IOException

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

Throws:

IOException
