public class MediaPickerWithCropsValueConverter : PropertyValueConverterBase, IDeliveryApiPropertyValueConverter, IPropertyValueConverter, IDiscoverable

Constructors

MediaPickerWithCropsValueConverter(IPublishedMediaCache, IPublishedUrlProvider, IPublishedValueFallback, IJsonSerializer, IApiMediaWithCropsBuilder)

Declaration

public MediaPickerWithCropsValueConverter(IPublishedMediaCache publishedMediaCache, IPublishedUrlProvider publishedUrlProvider, IPublishedValueFallback publishedValueFallback, IJsonSerializer jsonSerializer, IApiMediaWithCropsBuilder apiMediaWithCropsBuilder)

Parameters

Type	Name	Description
IPublishedMediaCache	publishedMediaCache
IPublishedUrlProvider	publishedUrlProvider
IPublishedValueFallback	publishedValueFallback
IJsonSerializer	jsonSerializer
IApiMediaWithCropsBuilder	apiMediaWithCropsBuilder

Methods

ConvertIntermediateToDeliveryApiObject(IPublishedElement, IPublishedPropertyType, PropertyCacheLevel, object?, bool, bool)

Converts a property intermediate value to an Object value for Delivery API representation.

Declaration

public object? ConvertIntermediateToDeliveryApiObject(IPublishedElement owner, IPublishedPropertyType propertyType, PropertyCacheLevel referenceCacheLevel, object? inter, bool preview, bool expanding)

Parameters

Type	Name	Description
IPublishedElement	owner	The property set owning the property.
IPublishedPropertyType	propertyType	The property type.
PropertyCacheLevel	referenceCacheLevel	The reference cache level.
object	inter	The intermediate value.
bool	preview	A value indicating whether conversion should take place in preview mode.
bool	expanding	A value indicating whether the property value should be expanded (if applicable).

Returns

Type	Description
object	The result of the conversion.

Remarks

The converter should know how to convert a null intermediate value, or any intermediate value indicating that no value has been assigned to the property. It is up to the converter to determine what to return in that case: either null, or the default value...

The referenceCacheLevel is passed to the converter so that it can be, in turn, passed to eg a PublishedFragment constructor. It is used by the fragment and the properties to manage the cache levels of property values. It is not meant to be used by the converter.

ConvertIntermediateToObject(IPublishedElement, IPublishedPropertyType, PropertyCacheLevel, object?, bool)

Converts a property intermediate value to an Object value.

Declaration

public override object? ConvertIntermediateToObject(IPublishedElement owner, IPublishedPropertyType propertyType, PropertyCacheLevel referenceCacheLevel, object? inter, bool preview)

Parameters

Type	Name	Description
IPublishedElement	owner	The property set owning the property.
IPublishedPropertyType	propertyType	The property type.
PropertyCacheLevel	referenceCacheLevel	The reference cache level.
object	inter	The intermediate value.
bool	preview	A value indicating whether conversion should take place in preview mode.

Returns

Type	Description
object	The result of the conversion.

Remarks

The referenceCacheLevel is passed to the converter so that it can be, in turn, passed to eg a PublishedFragment constructor. It is used by the fragment and the properties to manage the cache levels of property values. It is not meant to be used by the converter.

GetDeliveryApiPropertyCacheLevel(IPublishedPropertyType)

Gets the property cache level for Delivery API representation.

Declaration

public PropertyCacheLevel GetDeliveryApiPropertyCacheLevel(IPublishedPropertyType propertyType)

Parameters

Type	Name	Description
IPublishedPropertyType	propertyType	The property type.

Returns

Type	Description
PropertyCacheLevel	The property cache level.

GetDeliveryApiPropertyCacheLevelForExpansion(IPublishedPropertyType)

Gets the property cache level for Delivery API representation when expanding the property.

Declaration

public PropertyCacheLevel GetDeliveryApiPropertyCacheLevelForExpansion(IPublishedPropertyType propertyType)

Parameters

Type	Name	Description
IPublishedPropertyType	propertyType	The property type.

Returns

Type	Description
PropertyCacheLevel	The property cache level.

Remarks

Defaults to the value of GetDeliveryApiPropertyCacheLevel(IPublishedPropertyType).

GetDeliveryApiPropertyValueType(IPublishedPropertyType)

Gets the type of values returned by the converter for Delivery API representation.

Declaration

public Type GetDeliveryApiPropertyValueType(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.

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.

IsConverter(IPublishedPropertyType)

Gets a value indicating whether the converter supports a property type.

Declaration

public override bool IsConverter(IPublishedPropertyType propertyType)

Parameters

Type	Name	Description
IPublishedPropertyType	propertyType	The property type.

Returns

Type	Description
bool	A value indicating whether the converter supports a property type.

IsValue(object?, PropertyValueLevel)

Determines whether a value is an actual value, or not a value.

Declaration

public override bool? IsValue(object? value, PropertyValueLevel level)

Parameters

Type	Name	Description
object	value
PropertyValueLevel	level

Returns

Type	Description
bool?

Remarks

Called for Source, Inter and Object levels, until one does not return null.

Can return true (is a value), false (is not a value), or null to indicate that it cannot be determined at the specified level. For instance, if source is a string that could contain JSON, the decision could be made on the intermediate value. Or, if it is a picker, it could be made on the object value (the actual picked object).
