IEntityFieldsCore Interface

Interface for the Entity Fields types. An Entity Fields type is a collection of IEntityFieldCore objects which forms the total amount of fields for a given entity.

Namespace:  SD.LLBLGen.Pro.ORMSupportClasses
Assembly:  SD.LLBLGen.Pro.ORMSupportClasses (in SD.LLBLGen.Pro.ORMSupportClasses.dll) Version: 5.8.0.0 (5.8.21.0111)
Syntax
public interface IEntityFieldsCore : IEditableObject, 
	IList<IEntityFieldCore>, ICollection<IEntityFieldCore>, IEnumerable<IEntityFieldCore>, 
	IEnumerable, IList, ICollection

The IEntityFieldsCore type exposes the following members.

Properties
  NameDescription
Public propertyCount
Gets the number of slots allocated in this fields object.
Public propertyFieldsWithExpressionOrAggregate
Gets the fields with expression or aggregate.
Public propertyInheritanceInfoProviderToUse
Gets the inheritance info provider to use.
Public propertyIsChangedInThisEditCycle
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 ended.
Public propertyIsDirty
Gets / sets the flag if the contents of the EntityFields2 object is 'dirty', which means that one or more fields are changed.
Public propertyIsFixedSize
Gets a value indicating whether the IList has a fixed size.
(Inherited from IList.)
Public propertyIsReadOnly (Inherited from ICollectionIEntityFieldCore.)
Public propertyIsSynchronized
Gets a value indicating whether access to the ICollection is synchronized (thread safe).
(Inherited from ICollection.)
Public propertyItemInt32
Gets / sets the IEntityFieldCore on the specified Index.
Public propertyItemString
Gets the EntityField with the specified name.
Public propertyOwnPrimaryKeyFieldInfos
Gets the primary key field infos of the pk fields owned by this entity, so not the pk fields inherited from a supertype. If this entity isn't in a TPE inheritance hierarchy, this property is equal to PrimaryKeyFieldInfos
Public propertyPrimaryKeyFieldInfos
Gets the primary key field infos. Similar to PrimaryKeyFields, but this property doesn't trigger field creation.
Public propertyPrimaryKeyFields
List of IEntityFieldCore references which form the 'primary key', or uniquely identifying set of values for this set of fields, thus for the entity holding these fields. If possible use PrimaryKeyFieldInfos instead.
Public propertyState
The state of the IEntityFieldsCore object
Public propertySyncRoot
Gets an object that can be used to synchronize access to the ICollection.
(Inherited from ICollection.)

Methods
  NameDescription
Public methodAcceptChanges
Accepts the changes made. Used in databinding scenarios
Public methodAdd(Object)
Adds an item to the IList.
(Inherited from IList.)
Public methodAdd(T) (Inherited from ICollectionIEntityFieldCore.)
Public methodBeginEdit
Begins an edit on an object.
(Inherited from IEditableObject.)
Public methodCancelEdit (Inherited from IEditableObject.)
Public methodCleanAndPreserveExpressionsFromFields
Removes the expressions from fields and returns them in the dictionary, key is field index, value is the expression on that field. Only removes expressions from fields which have a non-empty containingobjectname, as those are real entity fields.
Public methodClear (Inherited from ICollectionIEntityFieldCore.)
Public methodClone
Clones this instance and its contents using a deep copy.
Public methodCloneAsDirty
Clones this object to a new IEntityFieldsCore object where all fields are changed and the object itself is marked dirty.
Public methodCompact
Compacts the list of fields so all empty slots are removed.
Public methodContains(Object)
Determines whether the IList contains a specific value.
(Inherited from IList.)
Public methodContains(T) (Inherited from ICollectionIEntityFieldCore.)
Public methodContract
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
Public methodCopyTo(Array, Int32)
Copies the elements of the ICollection to an Array, starting at a particular Array index.
(Inherited from ICollection.)
Public methodCopyTo(T, Int32) (Inherited from ICollectionIEntityFieldCore.)
Public methodDefineField(IEntityFieldCore, Int32)
Adds the specified field on the position indexInFields in the resultset.
Public methodDefineField(IEntityFieldCore, Int32, AggregateFunction)
Adds the specified field on the position indexInFields in the resultset.
Public methodDefineField(IEntityFieldCore, Int32, String)
Adds the specified field on the position indexInFields in the resultset.
Public methodDefineField(IEntityFieldCore, Int32, String, AggregateFunction)
Adds the specified field on the position indexInFields in the resultset.
Public methodDefineField(IEntityFieldCore, Int32, String, String)
Adds the specified field on the position indexInFields in the resultset.
Public methodDefineField(IEntityFieldCore, Int32, String, String, AggregateFunction)
Adds the specified field on the position indexInFields in the resultset.
Public methodDeserializeData
Deserializes the data of this fields object from the SerializationInfo object specified.
Public methodEndEdit (Inherited from IEditableObject.)
Public methodExpand
Expands this entity fields object by appending numberOfCells new cells to this object.
Public methodForcedValueWrite(Int32, Object)
Sets the current value for the field with the index specified to the currentValue specified without setting changed flags. From user code, use SetCurrentValue instead.
Public methodForcedValueWrite(Int32, Object, Object)
Sets the current value for the field with the index specified to the currentValue specified and the dbvalue to the dbvalue specified without setting changed flags. From user code, use SetCurrentValue instead.
Public methodGetAsEntityFieldCoreArray
Returns the complete list of IEntityFieldCore objects as an array of IEntityFieldCore objects.
Public methodGetCurrentValue
Gets the current value for the field at index specified.
Public methodGetDbValue
Gets the DB value for the field at index specified.
Public methodGetEntityFieldStates
Gets the field states for transaction state save
Public methodGetEntityNamesOfFields
Gets the entity names of fields.
Public methodGetEnumerator
Returns an enumerator that iterates through the collection.
(Inherited from IEnumerableIEntityFieldCore.)
Public methodGetFieldIndex
Gets the index of the field with the name specified
Public methodGetFieldInfo
Gets the field info for the field at the index specified.
Public methodGetFieldNames
Gets the field names of the fields contained in this fields object.
Public methodGetHashCode
Overrides the GetHashCode routine. It will calculate a hashcode for this set of entity fields using the eXclusive OR of the hashcodes of the primary key fields in this set of entity fields. That hashcode is returned. If no primary key fields are present, the hashcode of the base class is returned, which will not be unique.
Public methodGetIsChanged
Gets the IsChanged flag for the field at the index specified.
Public methodGetIsNull
Gets the IsNull value for the field with the index specified.
Public methodGetLinkedSuperTypeField

Sets the IsChanged flag for the field specified. Sets IsDirty to true if value is true.
Public methodSetValues
Sets the values for the fields, when this object is part of an entity.
Public methodShallowClone
Creates a shallow copy of this instance, which means that a new IEntityFieldsCore object is created but all membervariables are kept the same.
Public methodWriteXml
Writes the XML of this Fields object to the writer specified

Extension Methods
  NameDescription
Public Extension MethodInT
Creates a predicate which is true if there's an object of type T in values, which has for each property P a field in fields with the same name / alias and the value for property P is equal to the value of the field equivalent in the main query.
(Defined by InPredicateProducers.)
Public Extension MethodNotInT
Creates a predicate which is true if there's no object of type T in values, which has for each property P a field in fields with the same name / alias and the value for property P is equal to the value of the field equivalent in the main query.
