Syntax

public abstract class Relation : Object, IReadOnly<Relation>, IReadOnly

Constructors

Properties

AllowedChildTypes

Gets the types allowed for Child.

Declaration

protected abstract CatalogContentType[] AllowedChildTypes { get; }

Property Value

Type	Description
CatalogContentType[]

AllowedParentTypes

Gets the types allowed for Parent.

Declaration

protected abstract CatalogContentType[] AllowedParentTypes { get; }

Property Value

Type	Description
CatalogContentType[]

Child

The child catalog content in the parent-child relation.

Declaration

public ContentReference Child { get; set; }

Property Value

Type	Description
EPiServer.Core.ContentReference	The EPiServer.Core.ContentReference of the catalog content (CatalogContentBase) that is the child in the relation.

IsReadOnly

Indicates whether the current object instance is read-only.

Declaration

public bool IsReadOnly { get; }

Property Value

Type	Description
System.Boolean

Parent

The parent catalog content in the parent-child relation.

Declaration

public ContentReference Parent { get; set; }

Property Value

Type	Description
EPiServer.Core.ContentReference	The EPiServer.Core.ContentReference of the catalog content (CatalogContentBase) that is the parent in the relation.

SortOrder

Gets the sort order.

Declaration

public int SortOrder { get; set; }

Property Value

Type	Description
System.Int32	The sort order used when sorting all child objects of the same type with the same parent.

Methods

CreateWritableClone()

Creates a writable copy of the current object.

Declaration

public Relation CreateWritableClone()

Returns

Type	Description
Relation	A writable copy of the current object.

Remarks

The cloning is a deep-copy.

CreateWritableClone<T>()

Creates a writable copy of the current object.

Declaration

public T CreateWritableClone<T>()
    where T : Relation

Returns

Type	Description
T	A writable copy of the current object.

Type Parameters

Name	Description
T	The type to clone to.

Remarks

The cloning is a deep-copy.

CreateWritableCloneImplementation()

Implements the deep clone. Override to add any operations not handled by the base implementation (which includes a shallow copy by MemberwiseClone).

Declaration

protected virtual Relation CreateWritableCloneImplementation()

Returns

Type	Description
Relation	A cloned instance in read-write mode.

MakeReadOnly()

Changes the object instance into a read-only object.

Declaration

public void MakeReadOnly()

Remarks

After calling this method, any attempt to change the object instance or any contained object will generate a System.NotSupportedException. I.e. the semantics is "deep read-only".

Note! After setting an object to read-only it is not possible to revert back to read-write mode. You will have to call the CreateWritableClone method to get a copy that can be modified.

ThrowIfReadOnly()

Calls EPiServer.Data.Validator.ValidateNotReadOnly(EPiServer.Data.Entity.IReadOnly) which throws an exception if the item is in read-only mode. Subtypes should call this before accepting any modification to the object.

Declaration

protected void ThrowIfReadOnly()

ValidateType(ReferenceConverter, ContentReference, String, CatalogContentType[])

Validates that a content reference points to a catalog content of one of the specified types.

Declaration

protected void ValidateType(ReferenceConverter referenceConverter, ContentReference contentLink, string propertyName, params CatalogContentType[] allowedTypes)

Parameters

Type	Name	Description
ReferenceConverter	referenceConverter	The reference converter.
EPiServer.Core.ContentReference	contentLink	The content link.
System.String	propertyName	Name of the property.
CatalogContentType[]	allowedTypes	The allowed types.

Exceptions

Type	Condition
System.InvalidOperationException	Thrown if the reference is not of any of the allowed types.
