Parameters:

in - An InputStream.

Method Detail

readShortLE

public final short readShortLE()
                        throws java.io.IOException

reads a short. Little Endian version. it uses "readFully" meathod instead of reading each byte.

 readFully(c, 0, 2) is probably faster and use less memory than
 int ch1 = read();
 int ch2 = read();
 return (short)((ch2 << 8) + (ch1 << 0));
 

Throws:

java.io.IOException

readCharLE

public final char readCharLE()
                      throws java.io.IOException

Throws:

java.io.IOException

readIntLE

              throws java.io.IOException

Throws:
