SalFunctionalClass

Namespace: PPJ.Runtime

Assembly: PPJ.Web.50 (5.0.0.0)

Provides the runtime base for SAL user-defined functional classes.

C#

public class SalFunctionalClass

VB.NET

Public Class SalFunctionalClass

Supports runtime type lookup and the generated multiple-inheritance representation.

Example:

using PPJ.Runtime;

public class Customer : SalFunctionalClass
{
}

// In application code:
// Customer customer = new Customer();
// string name = customer.GetTypeName(); // "Customer"

Constructors

SalFunctionalClass()

Initializes a functional-class instance without a derived-owner reference.

Fields

Name	Type	Description	Value
_derived	Object	Stores the owning derived instance when this object represents an additional SAL base class.

Methods

CreateFromString(className)

Resolves and creates a functional class by name.

Parameter	Type	Description
className	String	The class name to resolve, giving precedence to the calling assembly.

Returns: SalFunctionalClass. A new instance of the resolved class, or null when the name cannot be resolved.

The resolved type must derive from SalFunctionalClass and be constructible through a parameterless constructor. Constructor and activation failures propagate to the caller.

GetTypeName()

Returns the simple name of the runtime class.

Returns: String. The runtime type name without its namespace.

IsDerivedFrom(className)

Tests the SAL inheritance relationship with a class resolved by name.

Parameter	Type	Description
className	String	The base class name to resolve, giving precedence to the calling assembly.

Returns: Boolean. True when the runtime type is compatible with the resolved type through TypeManager; false if resolution or the inheritance test fails.

IsDerivedFrom(type)

Tests the SAL inheritance relationship with a runtime type.

Parameter	Type	Description
type	Type	The type to test as a base class.

Returns: Boolean. The result of the TypeManager inheritance check for this instance's runtime type.

IsValidClassName(className)

Determines whether a class name can be resolved.

Parameter	Type	Description
className	String	The class name to resolve, giving precedence to the calling assembly.

Returns: Boolean. True if the name resolves to a type; otherwise, false.

This method checks resolution only. It does not establish that the type can be constructed as a SalFunctionalClass.
