Detailed Description

Import interfaces used by the interpreter.

The current DRLVM implementation describes the following import interfaces: interpreter import locking, exceptions handling, JVMTI and JNI functionality.

Typedefs
typedef ManagedObject	ManagedObject
Functions
VMEXPORT void	vm_monitor_enter_wrapper (ManagedObject *obj)
	Gains ownership over a monitor.
VMEXPORT void	vm_monitor_exit_wrapper (ManagedObject *obj)
	Releases ownership over a monitor.
VMEXPORT void	class_throw_linking_error_for_interpreter (Class_Handle ch, unsigned cp_index, unsigned opcode)
	Calls the class_throw_linking_error function that throws a linking error.
VMEXPORT JNIEnv *	get_jni_native_intf ()
	Returns the JNI environment.
VMEXPORT jbyte	jvmti_process_interpreter_breakpoint_event (jmethodID method, jlocation loc)
	A callback function for interpreter breakpoint processing.
VMEXPORT void	jvmti_process_single_step_event (jmethodID method, jlocation location)
	Enables single-step event processing.
VMEXPORT void	jvmti_process_frame_pop_event (jvmtiEnv *env, jmethodID method, jboolean was_popped_by_exception)
	Enables frame-pop event processing.
VMEXPORT GenericFunctionPointer	classloader_find_native (const Method_Handle method)
	Looks for a method in native libraries of a class loader.

Function Documentation

VMEXPORT void vm_monitor_enter_wrapper

(

ManagedObject *

obj

)

Gains ownership over a monitor.

The current thread blocks, if the specified monitor is owned by another thread.

Parameters:

[in]

obj

- the monitor object where the monitor is located

VMEXPORT void vm_monitor_exit_wrapper

(

ManagedObject *

obj

)

Releases ownership over a monitor.

Parameters:

[in]

obj

- the monitor object where the monitor is located

VMEXPORT void class_throw_linking_error_for_interpreter	(	Class_Handle	ch,
		unsigned	cp_index,
		unsigned	opcode
	)

Calls the class_throw_linking_error function that throws a linking error.

Parameters:

[in]	ch	- the class handle
[in]	cp_index	- the index in the constant pool
[in]	opcode	- the opcode of bytecodes

VMEXPORT JNIEnv* get_jni_native_intf

(

)

Returns the JNI environment.

Returns:

The JNI environment associated with this thread.

VMEXPORT jbyte jvmti_process_interpreter_breakpoint_event	(	jmethodID	method,
		jlocation	loc
	)

A callback function for interpreter breakpoint processing.

Parameters:

[in]	method	- the method ID
[in]	loc	- the location

VMEXPORT void jvmti_process_single_step_event	(	jmethodID	method,
		jlocation	location
	)

Enables single-step event processing.

Parameters:

[in]	method	- the method ID
[in]	location	- the location

VMEXPORT void jvmti_process_frame_pop_event	(	jvmtiEnv *	env,
		jmethodID	method,
		jboolean	was_popped_by_exception
	)

Enables frame-pop event processing.

Parameters:

[in]	env	- the jvmti environment
[in]	method	- the method ID
[in]	was_popped_by_exception	- if the frame was popped by exception

VMEXPORT GenericFunctionPointer classloader_find_native

(

const Method_Handle

method

)

Looks for a method in native libraries of a class loader.

Parameters:

[in]

method

- a searching native-method structure

Returns:

The pointer to found a native function.

Note:

The function raises UnsatisfiedLinkError with a method name in an exception message, if the specified method is not found.
