Detailed Description

Service definition of the object.

There are the following types of services: constructors, object methods, and class methods. Using this definition, the service marshalling is implemented. The user can gain access to this structure to acquire the attributes of the service.

The service definitions are stored in an array with the special last service definition having an empty name.

Member Function Documentation

unsigned MServiceDefinition::GetNumberOfParameters

(

)

const

Return the number of parameters of this service.

Precondition

The object is built correctly. There are some debug asserts.

const MVariant::Type* MServiceDefinition::GetParameterTypes

(

)

const

Return an array of parameter types.

Precondition

The object is built correctly. There are some debug asserts.

MVariant::Type MServiceDefinition::GetReturnType

(

)

const

Return service type, or MVariant::VAR_EMPTY if this is a procedure.

Precondition

The object is built correctly. There are some debug asserts.

bool MServiceDefinition::IsClassService ( ) const

inline

True if this is a class service rather than an object service.

Class service is called static service in C++.

Precondition

The parameter is in range of ServiceType enumeration. There is a debug check.

bool MServiceDefinition::IsProcedure ( ) const

inline

Whether this service is procedure or function.

Precondition

The object is built correctly. There are some debug asserts.

Member Data Documentation

char MServiceDefinition::m_name[MAXIMUM_SERVICE_NAME_LENGTH]

Name of the service.

Internally, if the name is a string containing only binary zeros, it means this structure is the last in the service list.

int MServiceDefinition::m_overloadedNumberOfParameters

If the procedure has overloaded parameters, this is the number of them.

If this is not an overloaded procedure, this value is -1.
