Properties| Name | Description | |
|---|---|---|
 | Count |
The number of fields allocated in this object.
|
| FieldsWithExpressionOrAggregate |
Gets the fields with expression or aggregate.
|
 | InEntityDataMode |
Gets a value indicating whether this object is in entity data mode (part of an entity) or not.
|
| IsChangedInThisEditCycle |
Flag to signal if the entity fields have changed during an edit cycle which is controlled outside this IEntityFieldsCore object. If set to
true, EndEdit will succeed, otherwise EndEdit will ignore any changes, since these are made in a previous edit cycle which is already

Gets a value indicating whether the IList is read-only.
|
| IsSynchronized |
Gets a value indicating whether access to the ICollection is synchronized (thread safe).
|
| ItemInt32 |
Gets / sets the field on the specified Index.
|
| ItemString |
Gets the field with the specified name.
|
| PrimaryKeyFields |
List of field references which form the primary key. Returns empty list if this object isn't part of an entity.
|
| State |
The state of the Entity Fields object, the heart and soul of every EntityObject.
|
| SyncRoot |
Not supported
|
| WrappedFieldsArray |
Gets the wrapped fields array.
|
Methods| Name | Description | |
|---|---|---|
 | Add |
Adds an item to the IList.
|
| Clear |
Not supported
|
| Compact |

|
| Contains |
Determines whether the IList contains a specific value.
|
| Contract |
Contracts the list of fields so all empty slots at the end of the list of fields are removed. Doesn't perform a contract operation if the
fields object is empty
|
 | ConvertToProjectors |
Converts the fields in the instance passed in to a new list of IEntityPropertyProjector instances which is ready to be used in a projection
|
| CopyTo | |
| CreateDeepClone |

|
| CreateDeepCloneAsDirty |
Clones this object to a new EntityFieldsCore<TField> object where all fields are changed and the object itself is marked dirty.
|
| CreateFieldInstanceImpl |
Creates a new TField instance and stores it in entityfields[index]. If this object is not in entity data mode, this method is a no-op.
|
| CreateShallowClone |
Creates a shallow copy of this instance, which means that a new object is created but all membervariables are kept the same.
|
| DefineField(IEntityFieldCore, Int32) |
Adds the specified field on the position indexInFields in the resultset.
|
| DefineField(IEntityFieldCore, Int32, AggregateFunction) |
Adds the specified field on the position indexInFields in the resultset.
|
| DefineField(IEntityFieldCore, Int32, String) |
Adds the specified field on the position indexInFields in the resultset.
|
| DefineField(IEntityFieldCore, Int32, String, AggregateFunction) |
Adds the specified field on the position indexInFields in the resultset.
|
| DefineField(IEntityFieldCore, Int32, String, String) |
Adds the specified field on the position indexInFields in the resultset.
|
| DefineField(IEntityFieldCore, Int32, String, String, AggregateFunction) | Adds the specified field on the position indexInFields in the resultset. |
| Equals |
Compares passed in object with the given object. This is a compare of PK fields. These have to be the same in VALUES.
When the values are not the same, or the type is not the same as the current type, false is returned, true otherwise.
When this doesn't have any PK fields, all fields are compared. null values are considered as the same value.
(Overrides ObjectEquals(Object).) |
| Expand |
Expands this entity fields object by appending numberOfCells new cells to this 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.) |
