void jvmti_method_enter_callback

(

Method_Handle

method

)

Method enter callback which is called from all JIT compiled methods, This callback is called before synchronization is done for synchronized methods.

Garbage collector should be enabled.

Parameters:

method

- handle of the called method

void jvmti_method_exit_callback	(	Method_Handle	method,
		jvalue *	return_value
	)

Method exit callback which is called from all JIT compiled methods.

This callback is called after synchronization is done for synchronized methods. Garbage collector should be enabled.

Parameters:

	method	- handle of the exiting method
	return_value	- the return value of the method if method is not void

void jvmti_field_access_callback	(	Field_Handle	field,
		Method_Handle	method,
		jlocation	location,
		ManagedObject *	object
	)

Field access callback which is called from JITted code compiled with <field access>=""> flag whenever access of field which has <field access="" mask>=""> set occures.

Garbage collector must be disabled.

Parameters:

	field	- handle of the field under access
	method	- handle of the method, which accesses field
	location	- location of code which accesses field
	object	- non GC-safe pointer to the object, which field is beeng accessed or NULL for static field

void jvmti_field_modification_callback	(	Field_Handle	field,
		Method_Handle	method,
		jlocation	location,
		ManagedObject *	object,
		jvalue *	new_value
	)

Field modification callback which is called from JITted code compiled with <field modification>=""> flag whenever modification of field which has <field modification="" mask>=""> set occures.

Garbage collector must be disabled.

Parameters:

	field	- handle of the field under modification
	method	- handle of the method, which modifies field
	location	- location of code which modifies field
	object	- non GC-safe pointer to the object, which field is beeng accessed or NULL for static field
	new_value	- pointer to the new value for the field

void jvmti_safe_point

(

)

Callback which is called frim JITted code.

Serves as a wrapper for hythread_safe_point().
