/**
|
|
|
|
* An object reference managed by the Dart VM garbage collector.
|
|
|
|
*
|
|
|
|
* Because the garbage collector may move objects, it is unsafe to
|
|
|
|
* refer to objects directly. Instead, we refer to objects through
|
|
|
|
* handles, which are known to the garbage collector and updated
|
|
|
|
* automatically when the object is moved. Handles should be passed
|
|
|
|
* by value (except in cases like out-parameters) and should never be
|
|
|
|
* allocated on the heap.
|
|
|
|
*
|
2011-11-11 19:31:04 +00:00
|
|
|
* Most functions in the Dart Embedding API return a handle. When a
|
|
|
|
* function completes normally, this will be a valid handle to an
|
|
|
|
* object in the Dart VM heap. This handle may represent the result of
|
|
|
|
* the operation or it may be a special valid handle used merely to
|
|
|
|
* indicate successful completion. Note that a valid handle may in
|
|
|
|
* some cases refer to the null object.
|
|
|
|
*
|
|
|
|
* When a function encounters a problem that prevents it from
|
|
|
|
* completing normally, it returns an error handle (See Dart_IsError).
|
|
|
|
* An error handle has an associated error message that gives more
|
|
|
|
* details about the problem (See Dart_GetError).
|
|
|
|
*
|
|
|
|
* When an unhandled exception occurs, it is returned as an error
|
|
|
|
* handle that has additional information about the exception (See
|
|
|
|
* Dart_ErrorHasException). This error handle retains information
|
|
|
|
* about the exception and the stack trace (See
|
|
|
|
* Dart_ErrorGetException, Dart_ErrorGetStacktrace,
|
|
|
|
* Dart_RethrowException).
|
2011-11-01 18:11:36 +00:00
|
|
|
*
|
|
|
|
* Local handles are allocated within the current scope (see
|
|
|
|
* Dart_EnterScope) and go away when the current scope exits. Unless
|
2011-11-11 19:31:04 +00:00
|
|
|
* otherwise indicated, callers should assume that all functions in
|
|
|
|
* the Dart embedding api return local handles.
|
2011-11-01 18:11:36 +00:00
|
|
|
*
|
|
|
|
* Persistent handles are allocated within the current isolate. They
|
2011-11-11 19:31:04 +00:00
|
|
|
* can be used to store objects across scopes. Persistent handles have
|
|
|
|
* the lifetime of the current isolate unless they are explicitly
|
|
|
|
* deallocated (see Dart_DeletePersistentHandle).
