Interface SciExpressionVisitor

All Known Implementing Classes:

SciExpressionVisitorAdapter

public interface SciExpressionVisitor

Visitor design pattern implementation for SciExpressions.

It defines defferent methods for visiting different kinds of expressions (member access expression, function call expression etc.). These methods are called up from SciExpression.accept method which determines the kind of the expression and runs this visitor's corresponding method, passing the expression as a parameter.

For example, this command

 someSciFunctionCallExpression.accept(mySciExpressionVisitor); //mySciExpressionVisitor implements SciExpressionVisitor

The methods of this interface can be also called from SciStatement.visitExpressions and SciScope.visitExpressions methods.

Every method returns a result of its actions. It can be null if it is not required from this visitor to return any information.
