C1.Util.DX Namespace

Classes

CallbackBase

Callback base implementation of ICallbackable.

ComArrayBase

A fast method to pass array of ComObject to C1.Win.DX methods.

ComArray<T>

A typed version of ComArrayBase

ComObject

Root IUnknown class to interop with COM object

ComObjectCallback

Base class for unmanaged callabackable Com object.

ComObjectEventArgs

Event args for ComObject used by ObjectTracker.

ComObjectShadow

A COM Interface Callback

Configuration

Global configuration.

CppObject

Root class for all Cpp interop object.

CppObjectShadow

An Interface shadow callback

DXUtil

Utility class.

DataStream

Provides a stream interface to a buffer located in unmanaged memory.

DisposeBase

Base class for a IDisposable class.

EqualityComparer

Provides IEqualityComparer<T> for default value types.

FunctionCallback

Represents a function callback.

HResultDescriptor

Descriptor used to provide detailed message for a particular Result.

ObjectReference

Contains information about a tracked COM object.

ObjectTracker

Track all allocated objects.

ShadowAttribute

Shadow attribute used to associate a COM callbackable interface to its Shadow implementation.

TagAttribute

A general purpose tag attribute.

Structs

Bool

A boolean value stored on 4 bytes (instead of 1 in .NET).

ColorF

Represents a color in the form of rgba.

DataBox

Provides access to data organized in 3D.

DataPointer

Pointer to a native buffer with a specific size.

DataRectangle

Provides access to data organized in 2D.

HResult

Result structure for COM methods.

Matrix3x2

Direct2D Matrix3x2 3x2.

Matrix4x4

Represents a 4x4 mathematical matrix.

Matrix5x4

Represents a 5x4 matrix for the built-in ColorMatrix effect.

Point2D

Structure specifing a point with double X and Y coordinates.

Point2F

Structure specifing a point with float X and Y coordinates.

Point2L

Structure specifing a point with integer X and Y coordinates.

PointerSize

The maximum number of bytes to which a pointer can point. Use for a count that must span the full range of a pointer. Equivalent to Windows type SIZE_T.

RectD

Structure specifing a rectangle with double Left, Top, Right, Bottom coordinates.

RectF

Defines a RectF. This structure is slightly different from System.Drawing.RectangleF as
it is internally storing Left, Top, Right, Bottom instead of Left, Top, Width, Height.

RectL

Defines a RectL. This structure is slightly different from System.Drawing.Rectangle as
it is internally storing Left, Top, Right, Bottom instead of Left, Top, Width, Height.

Size2D

Structure specifing a size with double Width and Height.

Size2F

Structure specifing a size with float Width and Height.

Size2L

Structure specifing a size with integer Width and Height.

Vector2

Represents a two dimensional mathematical vector.

Vector3

Represents a three dimensional mathematical vector.

Vector4

Represents a four dimensional mathematical vector.

ViewportF

Defines the viewport dimensions using float coordinates for (X, Y, Width, Height, MinDepth, MaxDepth).

Interfaces

ICallbackable

Use this interface to tag a class that is called by an unmanaged object. A ICallbackable class must dispose the Shadow on dispose.

IUnknown

Base interface for Component Object Model (COM).

Delegates

Action<T1, T2>

Encapsulates a method that has two parameters and does not return a value.

Func<TResult>

Encapsulates a method that has no parameters and returns a value of the type specified by the TResult parameter.

Func<T1, TResult>

Encapsulates a method that has one parameter and returns a value of the type specified by the TResult parameter.

Func<T1, T2, TResult>

Encapsulates a method that has two parameters and returns a value of the type specified by the TResult parameter.

GetValueFastDelegate<T>

A Delegate to get a property value from an object.

SetValueFastDelegate<T>

A Delegate to set a property value to an object.
