Inheritance diagram for stx::Grammar::PNBinaryArithmExpr:
Public Member Functions | |
| PNBinaryArithmExpr (const ParseNode *_left, const ParseNode *_right, char _op) | |
| Constructor from the parser: both operand subnodes and the operator id. | |
| virtual | ~PNBinaryArithmExpr () |
| Recursively delete parse tree. | |
| virtual AnyScalar | evaluate (const class SymbolTable &st) const |
| Applies the operator to the two recursive calculated values. | |
| virtual bool | evaluate_const (AnyScalar *dest) const |
| Returns false because this node isn't always constant. | |
| virtual std::string | toString () const |
| String representing (operandA op operandB). | |
Private Attributes | |
| const ParseNode * | left |
| Pointers to the left of the two child parse trees. | |
| const ParseNode * | right |
| Pointers to the right of the two child parse trees. | |
| char | op |
| Arithmetic operation to perform: left op right. | |
This node has two children.

| virtual AnyScalar stx::Grammar::PNBinaryArithmExpr::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::ParseNode::evaluate(), left, op, and right.
| virtual bool stx::Grammar::PNBinaryArithmExpr::evaluate_const | ( | AnyScalar * | dest | ) | const [inline, virtual] |
Returns false because this node isn't always constant.
Tries to calculate a constant subtree's value.
Implements stx::ParseNode.
Definition at line 598 of file ExpressionParser.cc.
References stx::AnyScalar::ATTRTYPE_INVALID, stx::ParseNode::evaluate_const(), left, op, and right.
char stx::Grammar::PNBinaryArithmExpr::op [private] |
Arithmetic operation to perform: left op right.
Further optimization would be to create an extra class for each op
