Copy

public class IntEnumDataAttribute<TObject, TEnum> : ColumnDataAttribute<TObject, TEnum>
where TObject : DomainObject

Public Class IntEnumDataAttribute(Of TObject As DomainObject, TEnum)
	Inherits ColumnDataAttribute(Of TObject, TEnum)

generic<typename TObject, typename TEnum>
where TObject : DomainObject
public ref class IntEnumDataAttribute : public ColumnDataAttribute<TObject, TEnum>

type IntEnumDataAttribute<'TObject, 'TEnum when 'TObject : DomainObject> =  
    class
        inherit ColumnDataAttribute<'TObject, 'TEnum>
    end

Type Parameters

TObject: The type of the domain object, which contains the attribute.
TEnum: The enum type

The IntEnumDataAttributeTObject, TEnum type exposes the following members.

Properties

	Name	Description
	BaseInfo	Gets the base information. (Inherited from DataAttributeBaseTObject.)
	ColumnName	The underlying data column name (Inherited from ColumnDataAttributeTObject, TValue.)
	DefaultValue	Gets the default value. (Inherited from DataAttributeBaseTObject.)
	Expressions	Gets the recalc expression. (Inherited from DataAttributeBaseTObject.)
	GetRow	The delegate that returns the buffer row, containing the storage column (Inherited from ColumnDataAttributeTObject, TValue.)
	IsBlob	Gets a value indicating whether this attribute data is BLOB. (Inherited from DataAttributeBaseTObject.)
	IsPersistent	Gets a value indicating whether this attribute is persistent. Only persistent attributes support track changes. (Inherited from DataAttributeBaseTObject.)
	LocalizedName	Gets the name of the attribute in the current UI culture. (Inherited from DataAttributeBaseTObject.)
	Name	Gets the name of the data Property (Inherited from DataAttributeBaseTObject.)
	PrimitiveValueType	Gets the primitive type or null. Used in public APIs to represent a complex value as a primitive value. (Inherited from DataAttributeBaseTObject.)
	ReadOnly	Is the data attribute read-only for user editing. (Inherited from DataAttributeBaseTObject.)
	SupportsGet	Gets a value indicating whether the attribute supports getting a value. (Inherited from DataAttributeBaseTObject.)
	SupportsSet	Gets a value indicating whether the attribute supports setting a value. (Inherited from DataAttributeBaseTObject.)
	TableName	The table used to persist and locally store the objects data (Inherited from ColumnDataAttributeTObject, TValue.)
	ValueType	Gets the value of the data attribute for the specified domain object (Inherited from DataAttributeTObject, TValue.)

Methods

	Name	Description
	FilterBy	Creates and returns filter condition for the data attribute (Inherited from ColumnDataAttributeTObject, TValue.)
	GetComplexTypeAccessor	Gets the complex type value accessor or null if the attribute does not support it. Complex type values are frequently used in Entity Data Models. (Inherited from DataAttributeBaseTObject.)
	GetDisplayValueAccessor	Gets the display text accessor or null if the attribute does not support it. The display value is localized in the current thread culture and is suitable for displaying and modification by end users. (Inherited from ColumnDataAttributeTObject, TValue.)
	GetInvariantStringAccessor	Gets the culture-neutral text value accessor or null if the attribute does not support it. The text value represents the values for import/export to text files or streams. (Inherited from ColumnDataAttributeTObject, TValue.)
	GetPrimitiveValueAccessor	Gets the primitive value accessor or null if the attribute does not support it. Used in public APIs to represent a complex value as a primitive value. (Inherited from DataAttributeBaseTObject.)
	GetUntypedValue	Gets the value of the data attribute for the specified domain object (Inherited from DataAttributeBaseTObject.)
	GetUntypedValueForRow	Gets the value of the attribute from any compatible buffer row (Overrides ColumnDataAttributeTObject, TValueGetUntypedValueForRow(IBufferRow, Boolean).)
	GetValue	Gets the value of the data attribute for the specified domain object (Inherited from DataAttributeTObject, TValue.)
	HasValue	Determines whether the specified object has value for the data attribute. (Inherited from DataAttributeBaseTObject.)
	OnDataAttributeChanged	Raises the DataAttributeChanged event. (Inherited from DataAttributeBaseTObject.)
	Prepare	Performs attribute-specific work to prepare the attribute. For example calculated attributes must be compiled. Called by the system after the attribute is added to the repository. (Inherited from DataAttributeBaseTObject.)
	SetDefaultValue	Sets the attribute to its default value. (Inherited from DataAttributeBaseTObject.)
	SetUntypedValue	Sets the value of the data attribute for the specified entity object (Inherited from DataAttributeBaseTObject.)
	SetUntypedValueForRowCore	Sets the value of the attribute for any compatible buffer row (Overrides ColumnDataAttributeTObject, TValueSetUntypedValueForRowCore(IBufferRow, Object).)
	SetValue	Sets the value of the data attribute for the specified domain object (Inherited from DataAttributeTObject, TValue.)
	ShouldRecalculateLateDefault	Returns true if the attribute should be recalculated for the specified object. (Inherited from DataAttributeBaseTObject.)
	ToString	Returns a String that represents this instance. (Inherited from ColumnDataAttributeTObject, TValue.)

Events

	Name	Description
	DataAttributeChanged	The data attribute changed event. Fired after the data attribute changes for an object. (Inherited from DataAttributeBaseTObject.)

Remarks

Enum types are stored differently from all other data types and that's why this class exists. This class stores enums based on their integer values in a base column of int type.
