Inheritance diagram for stx::Grammar::PNBinaryLogicExpr:
Public Member Functions | |
| PNBinaryLogicExpr (ParseNode *_left, ParseNode *_right, std::string _op) | |
| Constructor from the parser: both operand subnodes and the operator id. | |
| virtual | ~PNBinaryLogicExpr () |
| Recursively delete parse tree. | |
| bool | do_operator (bool left, bool right) const |
| Calculate the operator. | |
| std::string | get_opstr () const |
| Return the string of this operator. | |
| virtual AnyScalar | evaluate (const class SymbolTable &st) const |
| Applies the operator to the two recursive calculated values. | |
| virtual bool | evaluate_const (AnyScalar *dest) const |
| Applies the operator to the two recursive calculated const values. | |
| virtual std::string | toString () const |
| String (operandA op operandB). | |
| ParseNode * | detach_left () |
| Detach left node. | |
| ParseNode * | detach_right () |
| Detach right node. | |

Private Attributes | |
| ParseNode * | left |
| Pointers to the left of the two child parse trees. | |

anonymous enum [private] |
| virtual AnyScalar stx::Grammar::PNBinaryLogicExpr::evaluate | ( | const class SymbolTable & | st | ) | const [inline, virtual] |
Applies the operator to the two recursive calculated values.
The actual switching between types is handled by AnyScalar's operators.
Implements stx::ParseNode.

References stx::AnyScalar::ATTRTYPE_BOOL, do_operator(), stx::ParseNode::evaluate(), get_opstr(), stx::AnyScalar::getInteger(), stx::AnyScalar::getType(), left, and right.
| virtual bool stx::Grammar::PNBinaryLogicExpr::evaluate_const | ( | AnyScalar * | dest | ) | const [inline, virtual] |
Applies the operator to the two recursive calculated const values.
Determining if this node is constant is somewhat more tricky than with the other parse nodes: AND with a false operand is always false. OR with a true operand is always true.
