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:

aOther: the reference to compare this with.

Finalize protected virtual (declared in Object)

method Finalize

void Finalize()

func Finalize()

void 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

Type GetType()

func GetType() -> Type

Type GetType()

Function GetType() As 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:

a: left value
b: right value

ToString virtual (declared in Object)

Gets the string representation of this method.

method ToString: String

String ToString()

func ToString() -> String

String ToString()

Function ToString() As String

Call

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.
