Syntax

public class RadObjectType
Remarks

RadObjectType serves as a lightweight type descriptor that maintains hierarchical relationships and provides efficient type checking for RadObject-derived classes. It supports the dependency property system by providing fast type identification and inheritance checks.

Properties

BaseType

Gets the base type of this RadObjectType.

Declaration
public RadObjectType BaseType { get; }
Property Value
RadObjectType

The base RadObjectType, or null if this is the root type.

Id

Gets the unique identifier for this RadObjectType.

Declaration
public int Id { get; }
Property Value
System.Int32

An integer that uniquely identifies this type within the type system.

Name

Gets the name of this RadObjectType.

Declaration
public string Name { get; }
Property Value
System.String

The name of the underlying .NET type.

SystemType

Gets the underlying .NET type represented by this RadObjectType.

Declaration
public Type SystemType { get; }
Property Value
System.Type

The System.Type that this RadObjectType represents.

Methods

FromSystemType(Type)

Gets the RadObjectType for the specified System.Type.

Declaration
public static RadObjectType FromSystemType(Type systemType)
Parameters
System.Type systemType

The .NET type to get the RadObjectType for.
Returns
RadObjectType

The RadObjectType associated with the specified type.
Remarks

This method creates or retrieves a RadObjectType for the given .NET type. It ensures type safety by validating that the type inherits from RadObject.

Exceptions
System.ArgumentNullException

Thrown when systemType is null.
System.ArgumentException

Thrown when systemType is not assignable from RadObject.

GetHashCode()

Returns a hash code for this instance based on the type identifier.

Declaration
public override int GetHashCode()
Returns
System.Int32

A hash code for this instance, suitable for use in hashing algorithms and data structures like a hash table.
Overrides
System.Object.GetHashCode()

IsInstanceOfType(RadObject)

Determines whether the specified RadObject is an instance of this type.

Declaration
public bool IsInstanceOfType(RadObject radObject)
Parameters
RadObject radObject

The RadObject to test.
Returns
System.Boolean

true if the RadObject is an instance of this type or a derived type; otherwise, false.
Remarks

This method walks up the type hierarchy to determine if the RadObject's type matches this RadObjectType or any of its base types.

IsSubclassOf(RadObjectType)

Determines whether this RadObjectType is a subclass of the specified RadObjectType.

Declaration
public bool IsSubclassOf(RadObjectType radObjectType)
Parameters
RadObjectType radObjectType

The RadObjectType to compare against.
Returns
System.Boolean

true if this type is a subclass of the specified type; otherwise, false.
Remarks

This method checks the inheritance hierarchy to determine if this type derives from the specified RadObjectType.
