CreateCapturePrototype(IType, IType)

Creates a 'capture' instruction prototype, which captures a (thrown) exception.

Declaration

public static IntrinsicPrototype CreateCapturePrototype(IType resultType, IType argumentType)

Parameters

Type	Name	Description
IType	resultType	The type of a captured exception.
IType	argumentType	The type of the exception to capture.

Returns

Type	Description
IntrinsicPrototype	A 'capture' instruction prototype.

CreateGetCapturedExceptionPrototype(IType, IType)

Creates a 'get_captured_exception' instruction prototype, which extracts the exception captured by a captured exception.

Declaration

public static IntrinsicPrototype CreateGetCapturedExceptionPrototype(IType resultType, IType argumentType)

Parameters

Type	Name	Description
IType	resultType	The type of the exception value returned by this operation.
IType	argumentType	The type of the captured exception to examine.

Returns

Type	Description
IntrinsicPrototype	A 'get_captured_exception' instruction prototype.

CreatePrototype(String, IType, IReadOnlyList<IType>)

Creates an exception handling intrinsic prototype.

Declaration

public static IntrinsicPrototype CreatePrototype(string operatorName, IType resultType, IReadOnlyList<IType> parameterTypes)

Parameters

Type	Name	Description
System.String	operatorName	The name of the operator represented by the exception handling intrinsic.
IType	resultType	The type of value produced by the intrinsic to create.
System.Collections.Generic.IReadOnlyList<IType>	parameterTypes	The types of the values the intrinsic takes as arguments.

Returns

Type	Description
IntrinsicPrototype	An exception handling intrinsic prototype.

CreateRethrowPrototype(IType)

Creates a 'rethrow' instruction prototype, which rethrows a captured exception. The difference between 'rethrow' and 'throw' is that the former takes a captured exception and retains stack trace information whereas the latter takes a (raw) exception value and constructs a new stack trace.

Declaration

public static IntrinsicPrototype CreateRethrowPrototype(IType capturedExceptionType)

Parameters

Type	Name	Description
IType	capturedExceptionType	The type of the captured exception to rethrow.

Returns

Type	Description
IntrinsicPrototype	A 'rethrow' intrinsic.

CreateThrowPrototype(IType)

Creates a 'throw' instruction prototype, which throws an exception.

Declaration

public static IntrinsicPrototype CreateThrowPrototype(IType exceptionType)

Parameters

Type	Name	Description
IType	exceptionType	The type of exception to throw.

Returns

Type	Description
IntrinsicPrototype	A 'throw' instruction prototype.
