Compares two specified field values for equality. This method is used for implementation of ticker contract.

writeObj

void writeObj(DataOutput out,
              Object value)
       throws IOException

Deprecated. Use writeObj(BufferedOutput, Object) which is faster.

Writes specified field value into specified data output.

Throws:

IOException - as specified data output does.

writeObj

void writeObj(com.devexperts.io.BufferedOutput out,
              Object value)
       throws IOException

Throws:

IOException - as specified data output does.

readObj

Object readObj(DataInput in)
        throws IOException

Deprecated. Use readObj(BufferedInput) which is faster.

Reads field value from specified data input and returns it to the caller.

Throws:

IOException - as specified data input does.
