CondensedCollectionExtensionsAllTSource Method

[This is preliminary documentation and is subject to change.]

Determines whether all elements of the collection satisfy a condition. Optimized for a CondensedCollection.

Namespace: Condensed.Linq
Assembly: Condensed (in Condensed.dll) Version: 0.1.0.0 (0.1.0.0)

Syntax

public static bool All<TSource>(
	this CondensedCollection<TSource> source,
	Func<TSource, bool> predicate
)

<ExtensionAttribute>
Public Shared Function All(Of TSource) ( 
	source As CondensedCollection(Of TSource),
	predicate As Func(Of TSource, Boolean)
) As Boolean

public:
[ExtensionAttribute]
generic<typename TSource>
static bool All(
	CondensedCollection<TSource>^ source, 
	Func<TSource, bool>^ predicate
)

[<ExtensionAttribute>]
static member All : 
        source : CondensedCollection<'TSource> * 
        predicate : Func<'TSource, bool> -> bool

Parameters

source: Type: CondensedCondensedCollectionTSource
The collection to evaluate.
predicate: Type: SystemFuncTSource, Boolean
A function to test each element for a condition.

Type Parameters

TSource: The type of the elements of source.

Return Value

Type: Boolean
true if every element of the source sequence passes the test in the specified predicate, or if the sequence is empty; otherwise, false.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type CondensedCollectionTSource. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

Remarks

This implementation of All() is specialized for a CondensedCollection and tries to take advantage of the CondensedCollection's knowledge of unique values in order to improve performance. If you would rather use the normal LINQ extension method then cast the CondensedCollection to an IListT to use the AllTSource(IEnumerableTSource, FuncTSource, Boolean) implementation.
