public CallbackFunction(Func<ScriptExecutionContext, CallbackArguments, DynValue> callBack, string name = null)
Parameters
Func<ScriptExecutionContext, CallbackArguments, DynValue> callBack

The callback function to be called.
System.String name

The callback name, used in stacktraces, debugger, etc..

Properties

System.Object

ClrCallback

Gets the call back.

Declaration
public Func<ScriptExecutionContext, CallbackArguments, DynValue> ClrCallback { get; }
Property Value
Func<ScriptExecutionContext, CallbackArguments, DynValue>

The call back.

DefaultAccessMode

Gets or sets the default access mode used when marshalling delegates

Declaration
public static InteropAccessMode DefaultAccessMode { get; set; }
Property Value
InteropAccessMode

Parameters
Script script

The script.
Delegate del

The delegate.
InteropAccessMode accessMode

The access mode.
Returns
CallbackFunction

FromMethodInfo(Script, MethodInfo, Object, InteropAccessMode)

Creates a CallbackFunction from a MethodInfo relative to a function.

Declaration
public static CallbackFunction FromMethodInfo(Script script, MethodInfo mi, object obj = null, InteropAccessMode accessMode = InteropAccessMode.Default)
Parameters
Script script

The script.
System.Reflection.MethodInfo mi

The MethodInfo object.
System.Object obj

The object to which the function applies, or null for static methods.
