PublishedPropertyBase(IPublishedPropertyType, PropertyCacheLevel)

Initializes a new instance of the PublishedPropertyBase class.

Declaration

protected PublishedPropertyBase(IPublishedPropertyType propertyType, PropertyCacheLevel referenceCacheLevel)

Parameters

Type	Name	Description
IPublishedPropertyType	propertyType
PropertyCacheLevel	referenceCacheLevel

Properties

Alias

Gets the alias of the property.

Declaration

public string Alias { get; }

Property Value

Type	Description
System.String

PropertyType

Gets the property type.

Declaration

public IPublishedPropertyType PropertyType { get; }

Property Value

Type	Description
IPublishedPropertyType

ReferenceCacheLevel

Gets the property reference cache level.

Methods

GetDeliveryApiValue(Boolean, String, String)

Gets the object value of the property for Delivery API representation.

Declaration

public abstract object GetDeliveryApiValue(bool expanding, string culture = null, string segment = null)

Parameters

Type	Name	Description
System.Boolean	expanding
System.String	culture
System.String	segment

Returns

Type	Description
System.Object

Remarks

The value is what you want to use when rendering content through the Delivery API.

It can be null, or any type of CLR object.

It has been fully prepared and processed by the appropriate converter.

GetSourceValue(String, String)

Gets the source value of the property.

Declaration

public abstract object GetSourceValue(string culture = null, string segment = null)

Parameters

Type	Name	Description
System.String	culture
System.String	segment

Returns

Type	Description
System.Object

Remarks

The source value is whatever was passed to the property when it was instantiated, and it is somewhat implementation-dependent -- depending on how the IPublishedCache is implemented.

The XmlPublishedCache source values are strings exclusively since they come from the Xml cache.

For other caches that get their source value from the database, it would be either a string, an integer (Int32), a date and time (DateTime) or a decimal (double).

If you're using that value, you're probably wrong, unless you're doing some internal Umbraco stuff.

GetValue(String, String)

Gets the object value of the property.

Declaration

public abstract object GetValue(string culture = null, string segment = null)

Parameters

Type	Name	Description
System.String	culture
System.String	segment

Returns

Type	Description
System.Object

Remarks

The value is what you want to use when rendering content in an MVC view ie in C#.

It can be null, or any type of CLR object.

It has been fully prepared and processed by the appropriate converter.

HasValue(String, String)

Gets a value indicating whether the property has a value.

Declaration

public abstract bool HasValue(string culture = null, string segment = null)

Parameters

Type	Name	Description
System.String	culture
System.String	segment

Returns

Type	Description
System.Boolean

Remarks

This is somewhat implementation-dependent -- depending on whatever IPublishedCache considers a missing value.

The XmlPublishedCache raw values are strings, and it will consider missing, null or empty (and that includes whitespace-only) strings as "no value".

Other caches that get their raw value from the database would consider that a property has "no value" if it is missing, null, or an empty string (including whitespace-only).
