Call

Call a method given a set of arguments and flags. Note that this low level method does NO error checking (as it doesn't know the signature of the target method).

 

class method Call(aAddress: ^void; aCallingConv: CallingConvention; var aParams: array of Object; aParameterFlags: array of ArgumentMode; aParameterTypes: array of Type; aResultType: Type): Object

 

static Object Call(void* aAddress, CallingConvention aCallingConv, ref Object[] aParams, ArgumentMode[] aParameterFlags, Type[] aParameterTypes, Type aResultType)

 

static func Call(_ aAddress: UnsafeMutablePointer<void>, _ aCallingConv: CallingConvention, _ aParams: Object..., _ aParameterFlags: ArgumentMode..., _ aParameterTypes: Type..., _ aResultType: Type) -> Object

 

static Object Call(void* aAddress, CallingConvention aCallingConv, __ref Object[] aParams, ArgumentMode[] aParameterFlags, Type[] aParameterTypes, Type aResultType)

 

Shared Function Call(aAddress As Ptr(Of Void), aCallingConv As CallingConvention, ByRef aParams As Object(), aParameterFlags As ArgumentMode(), aParameterTypes As Type(), aResultType As Type) As Object

Parameters:

  • aAddress: Address of the method itself.
  • aCallingConv: Calling convention for the method. Ignored for non i386.
  • aParams: array of parameters to pass.
  • aParameterFlags: Array of parameter flags; these have to match in length with aParams.
  • aParameterTypes: Array of parameter types; these have to match in length with aParams.
  • aResultType: Result type, the call method returns a value of this type.

Equals (Object): Boolean  virtual    (declared in Object) iOS Simulator, Mac Catalyst-x86_64, macOS-x86_64, tvOS Simulator, Ubuntu-x86_64, watchOS Simulator-x86_64, Windows

 

method Equals(aOther: Object): Boolean

 

Boolean Equals(Object aOther)

 

func Equals(_ aOther: Object) -> Boolean

 

Boolean Equals(Object aOther)

 

Function Equals(aOther As Object) As Boolean

Parameters:

  • aOther:

Equals (Object): Boolean  virtual    (declared in Object) UIKit for Mac

Returns true if the target object matches this one, by default compares the reference.

 

method Equals(obj: Object): Boolean

 

Boolean Equals(Object obj)

 

func Equals(_ obj: Object) -> Boolean

 

Boolean Equals(Object obj)

 

Function Equals(obj As Object) As Boolean

Parameters:

  • obj: the reference to compare this with.

Finalize  protected virtual    (declared in Object) UIKit for Mac

Finalizer implementation. If not overriden it's not called at all, the runtime checks if there is an override before calling a finalizer.

 

method Finalize

 

Finalize()

 

func Finalize()

 

Finalize()

 

Sub Finalize()

GetHashCode  virtual    (declared in Object)

Returns a hashcode for this object. Overriden implementations should make sure that the number returned here is constant given the same object.

 

method GetHashCode: Int32

 

Int32 GetHashCode()

 

func GetHashCode() -> Int32

 

Int32 GetHashCode()

 

Function GetHashCode() As Int32

GetType    (declared in Object)

Returns the actual type of this class

 

method GetType: Type

ReferenceEquals    (declared in Object)

Compares two references for equivalence (even if they have an equals operator)

 

class method ReferenceEquals(a: Object; b: Object): Boolean

 

static Boolean ReferenceEquals(Object a, Object b)

 

static func ReferenceEquals(_ a: Object, _ b: Object) -> Boolean

 

static Boolean ReferenceEquals(Object a, Object b)

 

Shared Function ReferenceEquals(a As Object, b As Object) As Boolean

Parameters:
