Properties
  NameDescription
Public propertyCount
The number of fields allocated in this object.
Public propertyFieldsWithExpressionOrAggregate
Gets the fields with expression or aggregate.
Protected propertyInEntityDataMode
Gets a value indicating whether this object is in entity data mode (part of an entity) or not.
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 Entity Fields 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.
Public propertyIsReadOnly
Gets a value indicating whether the IList is read-only.
Public propertyIsSynchronized
Gets a value indicating whether access to the ICollection is synchronized (thread safe).
Public propertyItemInt32
Gets / sets the field on the specified Index.
Public propertyItemString
Gets the field with the specified name.
Public propertyPrimaryKeyFields
List of field references which form the primary key. Returns empty list if this object isn't part of an entity.
Public propertyState

Public propertySyncRoot
Not supported
Protected propertyWrappedFieldsArray
Gets the wrapped fields array.

Public methodAdd
Adds an item to the IList.
Public methodClear
Not supported
Public methodCompact
Compacts the list of fields so all empty slots are removed.
Public methodContains
Determines whether the IList contains a specific value.
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 methodStatic memberConvertToProjectors
Converts the fields in the instance passed in to a new list of IEntityPropertyProjector instances which is ready to be used in a projection
Public methodCopyTo
Copies the elements of the ICollection to an Array, starting at a particular Array index.
Protected methodCreateDeepClone
Clones this instance and its contents using a deep copy.
Protected methodCreateDeepCloneAsDirty
Clones this object to a new EntityFieldsCore<TField> object where all fields are changed and the object itself is marked dirty.
Protected methodCreateFieldInstanceImpl
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.
Protected methodCreateShallowClone
Creates a shallow copy of this instance, which means that a new object is created but all membervariables are kept the same.
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 methodEquals
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).)
Public methodExpand
Expands this entity fields object by appending numberOfCells new cells to this object.
Protected methodFinalize
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.
(Inherited from Object.)
Public methodForcedValueWrite(Int32, Object)
Sets the current value for the field with the index specified to the currentValue specified without setting changed flags.
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.
Public methodGetAsEntityFieldCoreArray
copy the complete list of IEntityField objects to an array of IEntityFieldCore objects. IEntityField objects implement IEntityFieldCore
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 methodGetEnumerator
Gets the enumerator for this 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, if this fields object is part of an entity. If not, it will return this object's hashcode, which is also done when no pk fields are present if this fields object is part of an entity
(Overrides ObjectGetHashCode.)
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 methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodIndexOf
Determines the index of a specific item in the IList.
Public methodInsert
Not supported
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodRemove
Not supported.
Public methodRemoveAt
Not supported.
Public methodSetCurrentValue
Sets the current value for the field at index specified.
Public methodSetDbValue
Sets the db value for the field at the index specified.
Public methodSetIsChanged
Sets the IsChanged flag for the field specified. Sets IsDirty to true if value is true.
Protected methodSetPersistenceInfoIfRequired
Sets the persistence info if required. Only used in selfservicing
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)

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.
(Defined by InPredicateProducers.)
