setPrecedenceTable

public static final void setPrecedenceTable(Operator[][] precArray)

Sets the precedences of the operators according to order in the supplied array. For example

                setPrecedenceTable(new Operator[][] 
                {       {OP_UMINUS},
                        {OP_NOT},
                        {OP_MUL,OP_DIV,OP_MOD},
                        {OP_PLUS,OP_MINUS},
                        {OP_LT,OP_LE},
                        {OP_GT,OP_GE},
                        {OP_EQ},
                        {OP_NE},
                        {OP_AND},
                        {OP_OR},
                        });
