EntityField Methods |
The EntityField type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Clone |
Creates a deep copy of this IEntityField object
(Overrides EntityFieldCoreClone.) |
 | CloneInternals |
Clones the internally referenced objects of this instance, so this instance after this method contains clones of its referenced internal objects.
(Inherited from EntityFieldCore.) |
| CompareTo |
Compares the given entityfield instance with this instance using a value compare with case sensitive comparer logic.
this is done by comparing the name, the source schema, object and column name. If there is any mismatch, the
comparisson is stopped and the result of the mismatching compare is returned.
(Overrides EntityFieldCoreCompareTo(Object).) |
| EntityFieldCoreInterpretGetValueInternal |
Internal implementation of the method which interprets this field in the entity passed in.
(Inherited from EntityFieldCore.) |
| Equals | (Overrides EntityFieldCoreEquals(Object).) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| ForcedCurrentValueWrite(Object) |
Overwrites the current value with the value passed. This bypasses value checking and field properties.
(Inherited from EntityFieldCore.) |
| ForcedCurrentValueWrite(Object, Object) |
Overwrites the current value with the value passed. This bypasses value checking and field properties like readonly.
(Inherited from EntityFieldCore.) |
| GetDiscriminatorColumnFlag |
Gets the discriminator column flag.
(Inherited from EntityFieldCore.) |
| GetHashCode |
Overrides the GetHashCode() method. It will return the hashcode of the value of the field as the hashcode.
(Overrides EntityFieldCoreGetHashCode.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ReadAdditionalElementsFromXml |
Reads the additional elements from XML. Reader is located on an unknown element. Implementers of this method have to handle this element.
(Overrides EntityFieldCoreReadAdditionalElementsFromXml(XmlReader).) |
| ReadDefinitionFromXml |
Deserializes the field's definition data on the xml reader into a field instance
(Inherited from EntityFieldCore.) |
| SetAggregateFunction |
Sets the EntityField's AggregateFunctionToApply property
|
| SetExpression |
Sets the Entity Field's ExpressionToToApply property
|
| SetFieldAlias |
Sets the field alias.
|
| SetObjectAlias |
Sets the entity field's ObjectAlias property to the specified value
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| WriteAdditionalElementsToXml |
Writes the additional elements to XML.
(Overrides EntityFieldCoreWriteAdditionalElementsToXml(XmlWriter).) |
| WriteDefinitionAsXml |
Serializes the field's definition as xml to the writer specified.
(Inherited from EntityFieldCore.) |
| WriteXml(XmlWriter, XmlFormatAspect) |
Writes the XML of this Field object to the writer specified
(Inherited from EntityFieldCore.) |
| WriteXml(XmlFormatAspect, XmlDocument, XmlNode) |
Converts this EntityField to an XmlNode.
