Syntax

public sealed class LowerBox : IntraproceduralOptimization

Constructors

LowerBox(IAssembly)

Creates an instance of the box-lowering transform for CIL.

Declaration

public LowerBox(IAssembly corlib)

Parameters

Type	Name	Description
IAssembly	corlib	The corlib assembly.

LowerBox(IMethod, IMethod)

Creates an instance of the box-lowering transform for CIL.

Declaration

public LowerBox(IMethod getTypeFromHandleMethod, IMethod createUninitializedObjectMethod)

Parameters

Type	Name	Description
IMethod	getTypeFromHandleMethod	A reference to a GetTypeFromHandle method that takes a type token and produces a type.
IMethod	createUninitializedObjectMethod	A reference to a GetUninitializedObject method that takes a type and produces a default-initialized object of that type.

LowerBox(TypeResolver)

Creates an instance of the box-lowering transform for CIL.

Declaration

public LowerBox(TypeResolver corlibResolver)

Parameters

Type	Name	Description
TypeResolver	corlibResolver	A type resolver for corlib.

Properties

CreateUninitializedObjectMethod

Gets a reference to a GetUninitializedObject method that takes a type and produces a default-initialized object of that type.

Declaration

public IMethod CreateUninitializedObjectMethod { get; }

Property Value

Type	Description
IMethod	A method reference.

GetTypeFromHandleMethod

Gets a reference to a GetTypeFromHandle method that takes a type token and produces a type.

Declaration

public IMethod GetTypeFromHandleMethod { get; }

Property Value

Type	Description
IMethod	A method reference.

Methods

Apply(FlowGraph)

Applies this intraprocedural optimization to a flow graph.

Declaration

public override FlowGraph Apply(FlowGraph graph)

Parameters

Type	Name	Description
FlowGraph	graph	The flow graph to transform.

Returns

Type	Description
FlowGraph	A transformed flow graph.

Overrides

IntraproceduralOptimization.Apply(FlowGraph)
