Method Detail

readUnsignedInt

public long readUnsignedInt()
                     throws IOException

Description copied from interface: DataInputExt

Reads 4 input bytes and returns a long value in the range 0-2^32.

Specified by:

readUnsignedInt in interface DataInputExt

Returns:

long value

Throws:

IOException

readUnsignedLong

public long readUnsignedLong()
                      throws IOException

Description copied from interface: DataInputExt

Reads 8 input bytes and returns a long value in the range 0-2^63. Values greater than 2^63 won't be read correctly since they are not supported by java.

Specified by:

readUnsignedLong in interface DataInputExt

Returns:

long value

Throws:

IOException

readASCII

public String readASCII()
                 throws IOException

Description copied from interface: DataInputExt

Reads a 0 terminated ASCII string from input stream

Specified by:

readASCII in interface DataInputExt

Returns:

string value

Throws:

IOException
