Constructor & Destructor Documentation

OpenTK.BindingsBase.BindingsBase

(

)

Constructs a new BindingsBase instance.

Definition at line 68 of file BindingsBase.cs.

        {
            DelegatesClass = this.GetType().GetNestedType("Delegates", BindingFlags.Static | BindingFlags.NonPublic);
            CoreClass = this.GetType().GetNestedType("Core", BindingFlags.Static | BindingFlags.NonPublic);

            if (CoreClass != null)
            {
                MethodInfo[] methods = CoreClass.GetMethods(BindingFlags.Static | BindingFlags.NonPublic);
                CoreFunctionMap = new SortedList<string, MethodInfo>(methods.Length); // Avoid resizing
                foreach (MethodInfo m in methods)
                {
                    CoreFunctionMap.Add(m.Name, m);

Member Function Documentation

abstract IntPtr OpenTK.BindingsBase.GetAddress

(

string

funcname

)

[protected, pure virtual]

Retrieves an unmanaged function pointer to the specified function.

Parameters:

funcname

A System.String that defines the name of the function.

Returns:

A IntPtr that contains the address of funcname or IntPtr.Zero, if the function is not supported by the drivers.

Note: some drivers are known to return non-zero values for unsupported functions. Typical values include 1 and 2 - inheritors are advised to check for and ignore these values.

Implemented in OpenTK.Compute.CL10.CL, and OpenTK.Graphics.GraphicsBindingsBase.

Member Data Documentation

readonly Type OpenTK.BindingsBase.CoreClass [protected]

A refection handle to the nested type that contains core functions (i.e. not extensions).

Definition at line 52 of file BindingsBase.cs.

readonly SortedList<string, MethodInfo> OpenTK.BindingsBase.CoreFunctionMap = new SortedList<string, MethodInfo>() [protected]

A mapping of core function names to MethodInfo handles.

Definition at line 57 of file BindingsBase.cs.

readonly Type OpenTK.BindingsBase.DelegatesClass [protected]

A reflection handle to the nested type that contains the function delegates.

Definition at line 47 of file BindingsBase.cs.

Property Documentation

bool OpenTK.BindingsBase.RebuildExtensionList [get, set, protected]

Gets or sets a System.Boolean that indicates whether the list of supported extensions may have changed.

Definition at line 92 of file BindingsBase.cs.

abstract object OpenTK.BindingsBase.SyncRoot [get, protected]

Gets an object that can be used to synchronize access to the bindings implementation.

This object should be unique across bindings but consistent between bindings of the same type. For example, ES10.GL, OpenGL.GL and CL10.CL should all return unique objects, but all instances of ES10.GL should return the same object.

Reimplemented in OpenTK.Compute.CL10.CL, OpenTK.Graphics.ES10.GL, OpenTK.Graphics.ES11.GL, OpenTK.Graphics.ES20.GL, and OpenTK.Graphics.OpenGL.GL.
