LiveMin(View<Int32>) Method

Computes the minimum value of a view of System.Int32 values.

Syntax

Visual Basic
C#

'Declaration
 
Public Overloads Shared Function LiveMin( _
   ByVal source As View(Of Integer) _
) As AggregationView(Of Integer,Integer)

public static AggregationView<int,int> LiveMin( 
   View<int> source
)

Parameters

source: A view containing the values to determine the minimum value of.

Return Value

A view representing the minimum of the values.

Remarks

If the source is empty or contains only nulls, an System.InvalidOperationException is thrown.

It is possible to use standard LINQ query operator Min instead of LiveMin. Both are "live" in the sense that they are recomputed automatically when any change occurs in the source. The difference is that Min will every time loop through the entire source collection and aggregate it from scratch, whereas LiveMin will use a more performant algorithm, will maintain its value incrementally, processing only those source items that actually changed.

Requirements

Target Platforms: Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
