ComputeImplementationType(ITypeInfo, IContext, Boolean)

Computes the type implementing the abstract type provided as the parameter.

Declaration
protected virtual ITypeInfo ComputeImplementationType(ITypeInfo abstractType, IContext activationContext = null, bool throwOnNotFound = true)
Parameters
Type Name Description
ITypeInfo abstractType

Indicates the abstract type.
IContext activationContext

Context for the activation.
System.Boolean throwOnNotFound

Indicates whether to throw an exception if an implementation type is not found.
Returns
Type Description
ITypeInfo

The implementation type for the provided ITypeInfo.

CreateInstance(ITypeInfo, IEnumerable<Object>, IContext)

Creates an instance of the provided ITypeInfo.

Declaration
public virtual object CreateInstance(ITypeInfo typeInfo, IEnumerable<object> args = null, IContext activationContext = null)
Parameters
Type Name Description
ITypeInfo typeInfo

Indicates the ITypeInfo used for the instantiation.
System.Collections.Generic.IEnumerable<System.Object> args

Constructor arguments.
IContext activationContext

Context for the activation.
Returns
Type Description
System.Object

An instance of the provided ITypeInfo.
Remarks

The typeInfo may be either an implementation type or an abstract type. If an abstract type is provided, then an implementation type is determined first and then instantiated.

GetImplementationType(ITypeInfo, IContext, Boolean)

Gets the type implementing the abstract type provided as the parameter.

Declaration
public virtual ITypeInfo GetImplementationType(ITypeInfo abstractType, IContext activationContext = null, bool throwOnNotFound = true)
Parameters
Type Name Description
ITypeInfo abstractType

Indicates the abstract type.
IContext activationContext

Context for the activation.
System.Boolean throwOnNotFound

Indicates whether to throw an exception if an implementation type is not found.
Returns
Type Description
ITypeInfo

The implementation type for the provided ITypeInfo.

GetImplementationTypes()

Gets the supported implementation types.

Declaration
protected virtual IEnumerable<ITypeInfo> GetImplementationTypes()
Returns
Type Description
System.Collections.Generic.IEnumerable<ITypeInfo>

An enumeration of implementation types.
Remarks

The ActivatorBase class provides always an empty list of implementation types. The inheritors should provide a proper list of supported implementation types annotated with ImplementationForAttribute, otherwise only non-abstract types will be resolved.

Declaration

Parameters
Type Name Description

Returns
Type Description
System.Reflection.TypeInfo

A TypeInfo.
