Detailed Description

The expression visitor translates clang expression to envision expression.

The way to interact it with it is to call TraverseStmt(someExpr) and then get the translated expression with the getLastExpression method

Member Function Documentation

createQualifiedReferenceWithTemplateArguments()

OOModel::ReferenceExpression * CppImport::ExpressionVisitor::createQualifiedReferenceWithTemplateArguments ( clang::SourceRange  sourceRange, const clang::NestedNameSpecifierLoc  qualifier, const clang::TemplateArgumentLoc *  templateArgs = nullptr, unsigned  numTArgs = 0, clang::Expr *  base = nullptr  )

private

Abstracts common code between all kinds of MemberExpr and DeclRefExpr.

Creates a reference expression with the name specified and sets prefixes and type arguments if specified.

setUtilities()

void CppImport::ExpressionVisitor::setUtilities

(

CppImportUtilities *

utils

)

This function should be called directly after instantiating this visitor.

The two classes have a dependency on each other.

translateArguments()

QList< OOModel::Expression * > CppImport::ExpressionVisitor::translateArguments	(	clang::Expr **	arguments,
		int	numArguments
	)

translateExpression()

OOModel::Expression * CppImport::ExpressionVisitor::translateExpression

(

clang::Stmt *

s

)

Translates the expression s.

Note that s should be an expression it is only declared as stmt for ease of use. Returns the translated expression or an error expression if it could not translate it.
