Methods

ConvertSourceToIntermediate(IPublishedElement, IPublishedPropertyType, Object, Boolean)

Converts a property source value to an intermediate value.

Declaration

public override object ConvertSourceToIntermediate(IPublishedElement owner, IPublishedPropertyType propertyType, object source, bool preview)

Parameters

Type	Name	Description
IPublishedElement	owner	The property set owning the property.
IPublishedPropertyType	propertyType	The property type.
System.Object	source	The source value.
System.Boolean	preview	A value indicating whether conversion should take place in preview mode.

Returns

Type	Description
System.Object	The result of the conversion.

Remarks

The converter should know how to convert a null source value, meaning that no value has been assigned to the property. The intermediate value can be null.

With the XML cache, source values come from the XML cache and therefore are strings.

With objects caches, source values would come from the database and therefore be either ints, DateTimes, decimals, or strings.

The converter should be prepared to handle both situations.

When source values are strings, the converter must handle empty strings, whitespace strings, and xml-whitespace strings appropriately, ie it should know whether to preserve white spaces.

CreateBlockEditorDataConverter()

Creates a specific data converter for the block property implementation.

Declaration

protected abstract BlockEditorDataConverter CreateBlockEditorDataConverter()

Returns

Type	Description
BlockEditorDataConverter

CreateBlockItemActivator()

Creates a specific block item activator for the block property implementation.

Declaration

protected abstract BlockPropertyValueConverterBase<TBlockModel, TBlockItemModel, TBlockLayoutItem, TBlockConfiguration>.BlockItemActivator<TBlockItemModel> CreateBlockItemActivator()

Returns

Type	Description
BlockPropertyValueConverterBase.BlockItemActivator<TBlockItemModel>

GetPropertyCacheLevel(IPublishedPropertyType)

Gets the property cache level.

Declaration

public override PropertyCacheLevel GetPropertyCacheLevel(IPublishedPropertyType propertyType)

Parameters

Type	Name	Description
IPublishedPropertyType	propertyType	The property type.

Returns

Type	Description
PropertyCacheLevel	The property cache level.

GetPropertyValueType(IPublishedPropertyType)

Gets the type of values returned by the converter.

Declaration

public override Type GetPropertyValueType(IPublishedPropertyType propertyType)

Parameters

Type	Name	Description
IPublishedPropertyType	propertyType	The property type.

Returns

Type	Description
Type	The CLR type of values returned by the converter.

Remarks

Some of the CLR types may be generated, therefore this method cannot directly return a Type object (which may not exist yet). In which case it needs to return a ModelType instance.
