◆ EstimateCost()
|
virtual |
Estimate the execution cost of the node (not including the cost of the children. The value returned should be based on the COST_* enumerant values defined in ispc.h.
Implements ASTNode.

References COST_DEREF, and DerefExpr::expr.
◆ GetType()
|
virtual |
Returns the Type of the expression.
Implements Expr.

References AssertPos, Module::errorCount, DerefExpr::expr, Type::GetReferenceTarget(), Expr::GetType(), and m.
Referenced by Print().
◆ Print()
|
virtual |
Prints the expression to standard output (used for debugging).
Implements Expr.
Definition at line 7369 of file expr.cpp.
References DerefExpr::expr, GetType(), Expr::Print(), and SourcePos::Print().
◆ TypeCheck()
|
virtual |
This method should perform type checking of the expression and return a pointer to the resulting expression. If an error is encountered, NULL should be returned.
Implements Expr.
