EntityFieldCore Methods |
The EntityFieldCore type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | Clone |
Creates a deep copy of this IEntityField2 object
|
 | CloneInternals |
Clones the internally referenced objects of this instance, so this instance after this method contains clones of its referenced internal objects.
|
| 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.
|
| EntityFieldCoreInterpretGetValueInternal |
Internal implementation of the method which interprets this field in the entity passed in.
|
| Equals | (Overrides ObjectEquals(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.
|
| ForcedCurrentValueWrite(Object, Object) |
Overwrites the current value with the value passed. This bypasses value checking and field properties like readonly.
|
| GetDiscriminatorColumnFlag |
Gets the discriminator column flag.
|
| GetHashCode |
Overrides the GetHashCode() method. It will return the hashcode of the value of the field as the hashcode.
(Overrides ObjectGetHashCode.) |
| 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.
|
| ReadDefinitionFromXml |
Deserializes the field's definition data on the xml reader into a field instance
|
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| WriteAdditionalElementsToXml |
Writes the additional elements to XML.
|
| WriteDefinitionAsXml |
Serializes the field's definition as xml to the writer specified.
|
| WriteXml |
Writes the XML of this Field object to the writer specified
