Detailed Description

Virtual class for abstraction nodes abort() if you try to typeCheck(), optimize() or emit() to force correct expansion into regular Aseba nodes.

Member Function Documentation

virtual Node* Aseba::AbstractTreeNode::expandAbstractNodes ( std::wostream *  dump)
pure virtual

Second pass to expand "abstract" nodes into more concrete ones.

Generically traverse the tree, expand the children, and perform garbagge collection.

Reimplemented from Aseba::Node.

Implemented in Aseba::UnaryArithmeticAssignmentNode, Aseba::ArithmeticAssignmentNode, Aseba::MemoryVectorNode, and Aseba::TupleVectorNode.
