Class SciVisitorUtil

public class SciVisitorUtil

This class contains a set of useful static methods for accepting a visitor by an enumeration of elements, expressions, statements or references.

Methods acceptToAll just accept visitor by a specified enumeration of elements, expressions, statements or references.

Methods acceptUntilStop behave more delicately, allowing to stop the process of accepting when the result of acception the visitor by an element of enumeration equals to the static variable STOP.

public final static Object STOP

This static variable is used to keep the "stop-sign" object.

public static void acceptToAll(SciElementEnumeration enum, SciElementVisitor visitor)

Makes each SciElement from the specified enumeration accept the specified visitor.

Parameters:

enum - SciElementEnumeration of SciElements

visitor - the SciElementVisitor to perform desired actions

public static void acceptToAll(SciReferenceEnumeration enum, SciReferenceVisitor visitor)

Makes each SciReference from the specified enumeration accept the specified visitor.

Parameters:

enum - SciReferenceEnumeration of SciReferences

visitor - the SciReferenceVisitor to perform desired actions

public static void acceptToAll(SciStatementEnumeration enum, SciStatementVisitor visitor)

Makes each SciStatement from the specified enumeration accept the specified visitor.

Parameters:

enum - SciStatementEnumeration of SciStatements

visitor - the SciStatementVisitor to perform desired actions

public static void acceptToAll(SciExpressionEnumeration enum, SciExpressionVisitor visitor)

Makes each SciExpression from the specified enumeration accept the specified visitor.

Parameters:

enum - SciExpressionEnumeration of SciExpressions

visitor - the SciExpressionVisitor to perform desired actions

public static Object acceptUntilStop(SciElementEnumeration enum, SciElementVisitor visitor)

Makes each SciElement from the specified enumeration accept the specified visitor until the result of accepting is equal to the static variable STOP.

Parameters:

enum - SciElementEnumeration of SciElements

visitor - the SciElementVisitor to perform desired actions

Returns: STOP variable if visitor's returned result is equal to the static variable STOP, null otherwise
