public class TraceConstructsEvalHook

extends JevaVisitorBase

A Jeva EvalHook which calls Trace methods to record method call and instance creation expressions, and records activities which use interpreted synchronized methods and blocks in the biography for the synchronizing object.

Method Summary

static Method	findInvokedCompiledMethod(Object target, IMethod iMethodSignature) returns null if interpreted method is invoked, else returns compiled method that is invoked for target (may override compile time signature)
static void	main(String[] arguments) Given a class name for a class in classpath, runs its public static void main(...) method with a TraceCallsEvalHook.
Object	visit(IJevaNode node, Object data) default -- do nothing
Object	visit(JNDConstructorDeclaration node, Object data) Trace calls received by interpreted constructors.
Object	visit(JNDMethodDeclaration node, Object data) Trace calls received by interpreted methods.
Object	visit(JNEInstanceCreationExpression node, Object data) Trace calls to compiled constructors.
Object	visit(JNEMethodInvocationExpression node, Object data) Trace calls to compiled methods, (Calls to interpreted methods are traced by visit(JNDMethodDeclaration,Object)).
Object	visit(JNSSynchronizedStatement node, Object data) Trace entry and exit from synchronized blocks.

Method Detail

visit

public Object visit(IJevaNode node,
                    Object data)

default -- do nothing

Overrides:

visit in class JevaVisitorBase

visit

public Object visit(JNEMethodInvocationExpression node,
                    Object data)

Trace calls to compiled methods, (Calls to interpreted methods are traced by visit(JNDMethodDeclaration,Object)).

Overrides:

visit in class JevaVisitorBase

visit

public Object visit(JNDMethodDeclaration node,
                    Object data)

Trace calls received by interpreted methods. (Calls invoking compiled methods are traced by visit(JNEMethodInvocationExpression,Object)

Overrides:

visit in class JevaVisitorBase

visit

public Object visit(JNEInstanceCreationExpression node,
                    Object data)

Trace calls to compiled constructors. (calls received by interpreted constructors are recorded by visit(JNDConstructorDeclaration,Object).

Overrides:

visit in class JevaVisitorBase

visit

public Object visit(JNDConstructorDeclaration node,
                    Object data)

Trace calls received by interpreted constructors. (Calls invoking compiled methods are traced by visit(JNEInstanceCreationExpression,Object)

Overrides:

visit in class JevaVisitorBase

visit

public Object visit(JNSSynchronizedStatement node,
                    Object data)

Trace entry and exit from synchronized blocks.

Overrides:

visit in class JevaVisitorBase

findInvokedCompiledMethod

public static Method findInvokedCompiledMethod(Object target,
                                               IMethod iMethodSignature)

returns null if interpreted method is invoked, else returns compiled method that is invoked for target (may override compile time signature)

main

public static void main(String[] arguments)
                 throws FileNotFoundException

Given a class name for a class in classpath, runs its public static void main(...) method with a TraceCallsEvalHook. Jeva will run compiled .class file if it exists, so delete it first.
