Constructor & Destructor Documentation

ExceptionWrapperBase() [1/2]

System::ExceptionWrapperBase::ExceptionWrapperBase

(

std::nullptr_t

)

Constructs a null-instance of ExceptionWrapper that does not represent any exception.

ExceptionWrapperBase() [2/2]

System::ExceptionWrapperBase::ExceptionWrapperBase

(

const ExceptionPtr &

ptr

)

Constructs a instance of ExceptionWrapper class that contains.

Parameters

ptr	Smart pointer to the instance of Exception class.

Member Function Documentation

Equals()

bool System::ExceptionWrapperBase::Equals

(

const ExceptionWrapperBase &

e

)

const

Determines if the current and the specified Exception objects are equal.

Parameters

e	The Exception object to compare the current object with

Returns

True if the currnent and the specified objects are the same object or both represent the same exception or both do not represent any exceptions (are null-objects), otherwise - false

Get()

ExceptionPtr System::ExceptionWrapperBase::Get ( ) const

inline

Returns smart pointer to the instance of Exception class that wrapper contains.

Returns

ptr Smart pointer to the instance of Exception class.

GetHashCode()

int System::ExceptionWrapperBase::GetHashCode

(

)

const

Calls GetHashCode() on exception pointer.

Returns

Result of GetHashCode() call on referenced object (if any) or 0.

Is()

bool System::ExceptionWrapperBase::Is

(

const System::TypeInfo &

target

)

const

Checks if exception object is of specific type or its child type. Follows C# 'is' semantics.

Parameters

target

Specifies target type to check against.

Returns

True if C# 'is'-style check is positive and false otherwise.

IsNull()

bool System::ExceptionWrapperBase::IsNull

(

)

const

Determines if the current Exception object is a null-object i.e. does not represent any exception.

Returns

True if the current Exception object is a null-object, otherwise - false

operator!=()

bool System::ExceptionWrapperBase::operator!=

(

const std::nullptr_t

)

const

Determines if the current Exception object is not a null-object i.e. represents an exception.

Returns

True if the current Exception object is not a null-object, otherwise - false

operator==() [1/2]

bool System::ExceptionWrapperBase::operator==

(

const ExceptionWrapperBase &

e

)

const

Determines if the current and the specified Exception objects are equal.

Parameters

e	The Exception object to compare the current object with

Returns

True if the currnent and the specified objects are the same object or both represent the same exception or both do not represent any exceptions (are null-objects), otherwise - false

operator==() [2/2]

bool System::ExceptionWrapperBase::operator==

(

const std::nullptr_t

)

const

Determines if the current Exception object is a null-object i.e. does not represent any exception.

Returns

True if the current Exception object is a null-object, otherwise - false

ToString()

String System::ExceptionWrapperBase::ToString

(

)

const

Calls ToString() on exception pointer.

Returns

Result of ToString() call on referenced object.

what()

virtual const char* System::ExceptionWrapperBase::what ( ) const

overridevirtualnoexcept

Calls the exception what() implementation.

Returns

The description of the exception.
