EngineFindExtensions.GetClosestDownstreamGridpoint Method (IList<EngineReach>, Double, Predicate<GridPoint>, Boolean)

Find the specified type of gridpoint which is closest to the given location downstream.

It is assumed that the EngineReach max and min chainages are containing the given chainage, otherwise null is returned.

Namespace: DHI.Mike1D.Engine
Assembly: DHI.Mike1D.Engine (in DHI.Mike1D.Engine.dll) Version: 19.0.0.0 (11.1.1.1111)

Syntax

C++

Copy

public static GridPoint GetClosestDownstreamGridpoint(
	this IList<EngineReach> reaches,
	double chainage,
	Predicate<GridPoint> match,
	bool allowExact
)

<ExtensionAttribute>
Public Shared Function GetClosestDownstreamGridpoint ( 
	reaches As IList(Of EngineReach),
	chainage As Double,
	match As Predicate(Of GridPoint),
	allowExact As Boolean
) As GridPoint

public:
[ExtensionAttribute]
static GridPoint^ GetClosestDownstreamGridpoint(
	IList<EngineReach^>^ reaches, 
	double chainage, 
	Predicate<GridPoint^>^ match, 
	bool allowExact
)

Parameters

reaches: Type: System.Collections.Generic.IList<EngineReach>
reaches to search, assuming they share the same reach id
chainage: Type: System.Double
Location to start search at
match: Type: System.Predicate<GridPoint>
The Predicate delegate that defines the conditions of the element to search for.
allowExact: Type: System.Boolean
Boolean specifying whether if a grid point is found at exactly the chainage value is to be included in the search.

Return Value

Type: GridPoint
Closest HGridPoint, null if none exists

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IList<EngineReach>. 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).
