Class MyParser

java.lang.Object
hussam.math.operations.parser.MyParser

All Implemented Interfaces:

OperationsParser

public class MyParser
extends java.lang.Object
implements OperationsParser

The default implementation for the OperationsParser interface.

Things to note down:
 1- Groups of expressions can be done using these charecter sets:
        { '(' , ')' }
 2- you can partition the arguments using these character sets:
        { ',' , '¡'}
 In the future we could supply extra brackts such as { '{' , '}' , '[' , ']' }
