Interface SciStatementVisitor

All Known Implementing Classes:

SciStatementVisitorAdapter

public interface SciStatementVisitor

Visitor design pattern implementation for SciStatements.

It defines defferent methods for visiting different kinds of statements (declaration statement, return statement etc.). These methods are called up from SciStatement.accept method which determines the kind of the statement and runs this visitor's corresponding method, passing the statement as a parameter.

For example, this command

 someSciDeclarationStatement.accept(mySciStatementVisitor); //mySciStatementVisitor implements SciStatementVisitor

The methods of this interface can be also called from SciScope.visitStatements 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.
