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  virtual    (declared in Object)

Default constructor.

 

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:
