public class ScriptExecutionContext : IScriptPrivateResource

Properties

AdditionalData

Gets or sets the additional data associated to this CLR function call.

Declaration
public object AdditionalData { get; set; }
Property Value
System.Object

CallingLocation

Gets the location of the code calling back

Declaration
public SourceRef CallingLocation { get; }
Property Value
SourceRef

CurrentGlobalEnv

Gets the current global env, or null if not found.

Declaration
public Table CurrentGlobalEnv { get; }
Property Value
Table

IsDynamicExecution

Gets a value indicating whether this instance is running a dynamic execution. Under a dynamic execution, most methods of ScriptExecutionContext are not reliable as the processing engine of the script is not "really" running or is not available.

Declaration
public bool IsDynamicExecution { get; }
Property Value
System.Boolean

OwnerScript

Gets the script owning this resource.

Declaration
public Script OwnerScript { get; }
Property Value
Script

The script owning this resource.

Methods

Call(DynValue, DynValue[])

Calls the specified function, supporting most cases. The called function must not yield.

Declaration
public DynValue Call(DynValue func, params DynValue[] args)
Parameters
DynValue func

The function; it must be a Function or ClrFunction or have a call metamethod defined.
DynValue[] args

The arguments.
Returns
DynValue

Exceptions
ScriptRuntimeException

If the function yields, returns a tail call request with continuations/handlers or, of course, if it encounters errors.

EmulateClassicCall(CallbackArguments, String, Func<LuaState, Int32>)

Calls a callback function implemented in "classic way". Useful to port C code from Lua, or C# code from UniLua and KopiLua. Lua : http://www.lua.org/ UniLua : http://github.com/xebecnan/UniLua KopiLua : http://github.com/NLua/KopiLua

Declaration
public DynValue EmulateClassicCall(CallbackArguments args, string functionName, Func<LuaState, int> callback)
Parameters
CallbackArguments args

The arguments.
System.String functionName

Name of the function - for error messages.
Func<LuaState, System.Int32> callback

The callback.
Returns
DynValue

EvaluateSymbol(SymbolRef)

Tries to get the reference of a symbol in the current execution state

Declaration
public DynValue EvaluateSymbol(SymbolRef symref)
Parameters
SymbolRef symref

Returns
DynValue

EvaluateSymbolByName(String)

Tries to get the value of a symbol in the current execution state

Declaration
public DynValue EvaluateSymbolByName(string symbol)
Parameters
System.String symbol

Returns
DynValue

FindSymbolByName(String)

Finds a symbol by name in the current execution state

Declaration
public SymbolRef FindSymbolByName(string symbol)
Parameters
System.String symbol

Returns
SymbolRef

GetBinaryMetamethod(DynValue, DynValue, String)

Gets the metamethod to be used for a binary operation using op1 and op2.

Declaration
public DynValue GetBinaryMetamethod(DynValue op1, DynValue op2, string eventName)
Parameters
DynValue op1

DynValue op2

System.String eventName

Returns
DynValue

GetCallingCoroutine()

Gets the coroutine which is performing the call

Declaration
public Coroutine GetCallingCoroutine()
Returns
Coroutine

GetMetamethod(DynValue, String)

Gets the specified metamethod associated with the given value.

Declaration
public DynValue GetMetamethod(DynValue value, string metamethod)
Parameters
DynValue value

The value.
System.String metamethod

The metamethod name.
Returns
DynValue

GetMetamethodTailCall(DynValue, String, DynValue[])

prepares a tail call request for the specified metamethod, or null if no metamethod is found.

Declaration
public DynValue GetMetamethodTailCall(DynValue value, string metamethod, params DynValue[] args)
Parameters
DynValue value

System.String metamethod

DynValue[] args

Returns
DynValue

GetMetatable(DynValue)

Gets the metatable associated with the given value.

Declaration
public Table GetMetatable(DynValue value)
Parameters
DynValue value

The value.
Returns
Table

GetScript()

Gets the script object associated with this request

Declaration
public Script GetScript()
Returns
Script

PerformMessageDecorationBeforeUnwind(DynValue, ScriptRuntimeException)

Performs a message decoration before unwinding after an error. To be used in the implementation of xpcall like functions.

Declaration
public void PerformMessageDecorationBeforeUnwind(DynValue messageHandler, ScriptRuntimeException exception)
Parameters
DynValue messageHandler

The message handler.
ScriptRuntimeException exception

The exception.
