Syntax
public class ExtensionCollection : DefinitionalObjectCollection<ObjectExtension>

The ExtensionCollection type exposes the following members.

Constructors
  NameDescription
Protected methodExtensionCollection
Initializes a new instance. The Owner property must be set explicitly after using this constructor.
Public methodExtensionCollection(ExtensibleObject)
Initializes a new instance.
Protected methodExtensionCollection(ExtensionCollection, CopyContext)
Initializes a new instance as a copy of an existing instance.

Properties
  NameDescription
Public propertyCount (Inherited from CollectionObjectExtension.)
Public propertyIsFrozen
Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an ObjectFrozenException will be thrown if an attempt is made to do so.
(Inherited from DefinitionalObjectCollectionT.)
Public propertyItem
Gets or sets the element at the specified index.
(Inherited from CollectionObjectExtension.)
Protected propertyItems (Inherited from CollectionObjectExtension.)
Public propertyOwner
Gets the owner of this collection.

Methods
  NameDescription
Public methodAdd (Inherited from CollectionObjectExtension.)
Public methodAddRange (Inherited from DefinitionalObjectCollectionT.)
Protected methodCheckForSameDefinition(DefinitionalObjectCollectionObjectExtension)
Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
(Overrides DefinitionalObjectCollectionTCheckForSameDefinition(DefinitionalObjectCollectionT).)
Protected methodCheckForSameDefinition(ExtensionCollection)
Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).
Public methodClear (Inherited from CollectionObjectExtension.)
Protected methodClearItems
Removes all elements from the collection.
(Overrides DefinitionalObjectCollectionTClearItems.)
Public methodClone
Clones this object using the specified context.
(Overrides DefinitionalObjectCollectionTClone(CopyContext).)
Protected methodComputeCurrentDefinitionHashCode
Computes a hash code based on the current properties of this object. Derived classes MUST override this method and compute a hash code that combines: a unique hash code seed, the base implementation result, and the hash codes of all new fields introduced by the derived class which are used in the CheckForSameDefinition(DefinitionalObjectCollectionT) method.
(Overrides DefinitionalObjectCollectionTComputeCurrentDefinitionHashCode.)
Public methodContains (Inherited from CollectionObjectExtension.)
Public methodCopyTo (Inherited from CollectionObjectExtension.)
Public methodEnumerateDependencies
Enumerates the dependencies of this object by calling EnumerateT(T) for each object that this object directly depends upon. Derived classes which contain additional dependencies MUST override this method, call the base implementation, and enumerate dependencies introduced by the derived class.
(Overrides DefinitionalObjectCollectionTEnumerateDependencies(DependencyEnumerator).)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from 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 methodFreeze
Freezes this object. Further attempts to modify it will result in an ObjectFrozenException.
(Inherited from DefinitionalObjectCollectionT.)
Protected methodFreezeAggregatedObjects
Called by Freeze to also freeze any objects that are considered to be a part of this object. Derived classes which contain additional aggregated objects MUST override this method, call the base implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be frozen in this method are frequently created in this object's constructor and are not settable via properties.
(Inherited from DefinitionalObjectCollectionT.)
Public methodGetByTypeT
Gets the first extension of the specified type that is in this collection.
Public methodGetDefinitionHashCode
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObjectCollectionT.)
Public methodGetEnumerator (Inherited from CollectionObjectExtension.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodIndexOf (Inherited from CollectionObjectExtension.)
Public methodInsert (Inherited from CollectionObjectExtension.)
Protected methodInsertItem
Inserts an element in the collection at the specified index.
(Overrides DefinitionalObjectCollectionTInsertItem(Int32, T).)
Public methodIsSameDefinition
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObjectCollectionT.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodRemove (Inherited from CollectionObjectExtension.)
Public methodRemoveAt (Inherited from CollectionObjectExtension.)
Protected methodRemoveItem
Removes the element at the specified index of the collection.
(Overrides DefinitionalObjectCollectionTRemoveItem(Int32).)
Protected methodSetItem
Replaces the element at the specified index.
(Overrides DefinitionalObjectCollectionTSetItem(Int32, T).)
Protected methodThrowIfFrozen
Throws ObjectFrozenException if this object IsFrozen. This method should be called from any method or property that modifies this object.
(Inherited from DefinitionalObjectCollectionT.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)
