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.
