Struct ValueFunc<T1, T2, R>

Represents a pointer to the method with two parameters and return type.

Implements
ICallable<DotNext.Func<T1, T2, R>>
IEquatable<ValueFunc<T1, T2, R>>
Namespace: DotNext
Assembly: DotNext.dll
Syntax
public struct ValueFunc<T1, T2, R> : ICallable<Func<T1, T2, R>>, ICallable, IEquatable<ValueFunc<T1, T2, R>>, ISupplier<T1, T2, R>
Type Parameters
Name Description
T1

The type of the first method parameter.
T2

The type of the second method parameter.
R

The type of the return value of the method that this pointer encapsulates.
Remarks

This method pointer is intended to call managed methods only.

Constructors

ValueFunc(Func<T1, T2, R>, Boolean)

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

Declaration
public ValueFunc(Func<T1, T2, R> func, bool wrap = false)
Parameters
Type Name Description
DotNext.Func<T1, T2, R> func

The delegate representing method.
Boolean wrap

true to wrap func 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.

ValueFunc(IntPtr)

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

Declaration
public ValueFunc(IntPtr methodPtr)
Parameters
Type Name Description
IntPtr methodPtr

The pointer to the static managed method.

ValueFunc(MethodInfo)

Initializes a new pointer to the method.

Declaration
public ValueFunc(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.
