IVsaEngine.IsCompiled Property
Gets a Boolean value that signifies whether a script engine has successfully compiled the current source state.
public: _property bool get_IsCompiled();
public bool IsCompiled { get; }
Public Property Get IsCompiled() As Boolean
Return Value
Returns true if the current source state of the engine is successfully compiled. Returns false if the script engine does not have a valid compiled state. The default value for this property is false.
Remarks
The script engine may return false even if there is a valid compiled state, but it is out of date; it will do this if the source state has been modified since the last compilation, that is, in cases where the IVsaEngine.IsDirty property is true.
Upon a call to the IVsaEngine.Run method, the engine evaluates the following conditions and proceeds accordingly:
If the most recent call to IVsaEngine.Compile fails, an EngineNotCompiled exception is thrown;
If there is compiled state loaded in the engine, this code is run;
if not, and if there is compiled state in the code cache, this code is run;
if not, and if a callback to IVsaSite.GetCompiledState returns compiled state, this code is run;
if not, the call fails and a GetCompiledStateFailed exception is propagated from step 3.
The following table shows the exceptions that the IsCompiled property can throw.
Exception Type |
Condition |
---|---|
EngineClosed |
The IVsaEngine.Close method has been called and the engine is closed. |
EngineBusy |
The engine is currently executing code for another thread. |
EngineNotInitialized |
