Constructor Detail

NumericArgument
public NumericArgument()

Description copied from class: Argument

Writes itself to stack.

Specified by:

writeToStack in class Argument

Parameters:

stack - it's byte array, where Argument will be written

offset - offset in stack

Description copied from class: Argument

Read itself from stack.

Specified by:

readFromStack in class Argument

Parameters:

stack - it's byte array, from which Argument will be restored

offset - offset in stack

Returns the value as bit representation.

Returns:

the numeric value represented by this object as bit representation.
