Struct ValueRefAction<T, TArgs>

Represents action that accepts arbitrary value by reference.

Implements

IEquatable<ValueRefAction<T, TArgs>>

Namespace: DotNext

Assembly: DotNext.dll

Syntax

public struct ValueRefAction<T, TArgs> : ICallable<RefAction<T, TArgs>>, ICallable, IEquatable<ValueRefAction<T, TArgs>>

Type Parameters

Name	Description
T	The type of the object to be passed by reference into the action.
TArgs	The type of the arguments to be passed into the action.

Remarks

This method pointer is intended to call managed methods only.

Constructors

ValueRefAction(RefAction<T, TArgs>, Boolean)

Initializes a new pointer based on extracted pointer from the delegate.

Declaration

public ValueRefAction(RefAction<T, TArgs> action, bool wrap = false)

Parameters

Type	Name	Description
RefAction<T, TArgs>	action	The delegate representing method.
Boolean	wrap	true to wrap `action` into this delegate; false to extract method pointer without holding reference to the passed delegate.

Remarks

You can use this constructor to create value delegate once and cache it using static readonly field for subsequent calls.

ValueRefAction(IntPtr)

Initializes a new delegate using pointer to the static managed method.

Declaration

public ValueRefAction(IntPtr methodPtr)

Parameters

Type	Name	Description
IntPtr	methodPtr	The pointer to the static managed method.

ValueRefAction(MethodInfo)

Initializes a new pointer to the method.

Declaration

public ValueRefAction(MethodInfo method)

Parameters

Type	Name	Description
MethodInfo	method	The method to convert into pointer.

Remarks

This constructor causes heap allocations because Reflection is needed to check compatibility of method's signature with the delegate type.
