ValueExpressionParserTUpdateExpressions(IEnumerablePropertyInfo, TypeRegistry) Method

public static Action<T> UpdateExpressions(
	IEnumerable<PropertyInfo> properties = null,
	TypeRegistry typeRegistry = null
)

Public Shared Function UpdateExpressions ( 
	Optional properties As IEnumerable(Of PropertyInfo) = Nothing,
	Optional typeRegistry As TypeRegistry = Nothing
) As Action(Of T)

public:
static Action<T>^ UpdateExpressions(
	IEnumerable<PropertyInfo^>^ properties = nullptr, 
	TypeRegistry^ typeRegistry = nullptr
)

static member UpdateExpressions : 
        ?properties : IEnumerable<PropertyInfo> * 
        ?typeRegistry : TypeRegistry 
(* Defaults:
        let _properties = defaultArg properties null
        let _typeRegistry = defaultArg typeRegistry null
*)
-> Action<'T> 

GSF.ComponentModel.ValueExpressionParser.UpdateExpressions = function(properties, typeRegistry);

Parameters

properties  IEnumerablePropertyInfo  (Optional)

Specific properties to target, or null to target all properties.

typeRegistry  TypeRegistry  (Optional)

Type registry to use when parsing TypeConvertedValueExpressionAttribute instances, or null to use DefaultTypeRegistry.

Return Value

This function is useful for generating a delegate to a compiled function that will execute expression assignments on objects of type T where properties of the type of have been decorated with TypeConvertedValueExpressionAttribute attributes. Note that the expression in the TypeConvertedValueExpressionAttribute attribute is expected to evaluate to a property such that it can be assigned the target type T property value.

Note
This function will assign current modeled property values back to expressions, this is often useful when a model is being synchronized to an external source, e.g., user interface elements.

This method is the inverse call for UpdateProperties(IEnumerablePropertyInfo, TypeRegistry).
