A collection parameterized by an IDefinition. Base class for ColumnDefinitionCollection and RowDefinitionCollection.

public class DefinitionCollection<T> : System.Collections.Generic.ICollection<T>, System.Collections.Generic.IEnumerable<T>, System.Collections.Generic.IList<T> where T : IDefinition

type DefinitionCollection<'T (requires 'T :> IDefinition)> = class
    interface IList<'T (requires 'T :> IDefinition)>
    interface ICollection<'T (requires 'T :> IDefinition)>
    interface seq<'T (requires 'T :> IDefinition)>
    interface IEnumerable

Type Parameters

T

Inheritance: Object
DefinitionCollection<T>

Derived: Xamarin.Forms.ColumnDefinitionCollection

Xamarin.Forms.RowDefinitionCollection

Implements: ICollection<T> IEnumerable<T> IList<T> IEnumerable

Remarks

Objects of type DefinitionCollection<T> are parameterized with a type of IDefinition.

Properties

Count	Gets the number of IDefinition instances contained in this DefinitionCollection<T>.
IsReadOnly	`false`. DefinitionCollection<T> instances can have items added to them and removed from them.
Item[Int32]	Gets or sets the value indexed by `index`.

Methods

Add(T)	Adds a IDefinition to the collection.
Clear()	Removes all values from this DefinitionCollection<T>.
Contains(T)	Returns a Boolean value that indicates whether or not this DefinitionCollection<T> contains the specified IDefinition.
CopyTo(T[], Int32)	Copies IDefinition instances from this DefinitionCollection<T> into an `array`, starting at the specified `arrayIndex` into `array`.
GetEnumerator()	Returns an enumerator that iterates through the IDefinition instances in this DefinitionCollection<T>.
IndexOf(T)	Returns the index of the first occurrence of `item` in this DefinitionCollection<T>.
Insert(Int32, T)	Inserts a IDefinition into this DefinitionCollection<T> at the location that is specified by `index`.
Remove(T)	Removes a IDefinition from this DefinitionCollection<T> and returns `true` if the item was removed.
RemoveAt(Int32)	Removes an item from this DefinitionCollection<T>.

Events

ItemSizeChanged

Event that is raised when the display size of item in the collection changes.

Explicit Interface Implementations

IEnumerable.GetEnumerator()

Gets an enumerator that can be used to iterate over the IDefinition instances in this DefinitionCollection<T>.
