virtual size_t IT_Reflect::ComplexType::get_attribute_count

(

)

const [pure virtual]

Return the count of attributes defined for this type.

Returns:

size_t

Exceptions:

ReflectException

Implemented in IT_Reflect::ComplexTypeImpl.

virtual const IT_Bus::QName& IT_Reflect::ComplexType::get_attribute_name

(

size_t

i

)

const [pure virtual]

Return the name of the ith attribute.

Returns:

reference to QName of selected attribute

Exceptions:

ReflectException

Implemented in IT_Reflect::ComplexTypeImpl.

virtual const Reflection* IT_Reflect::ComplexType::get_attribute_value

(

const IT_Bus::QName &

name

)

const [pure virtual]

Get read-only reflection of named attribute.

For optional attributes returns a 0 pointer if the attribute is missing.

Parameters:

name

Attribute name.

Returns:

Reflection of attribute or 0 if missing. Caller must _remove_ref().

Exceptions:

ReflectException

The attribute name is not valid.

virtual void IT_Reflect::ComplexType::remove_attribute

(

const IT_Bus::QName &

name

)

[pure virtual]

Remove an optional attribute.

Does nothing for non-optional attributes.

Parameters:

name

Attribute name.

Exceptions:

ReflectException

virtual Reflection* IT_Reflect::ComplexType::use_attribute_value

(

const IT_Bus::QName &

name

)

[pure virtual]

Use the named attribute.

Returns a reflection object that can be used to modify the attribute. For optional attributes returns a 0 pointer if the attribute is missing.

Parameters:

name

Attribute name.

Returns:

Reflection of attribute Caller must _remove_ref()

Exceptions:

ReflectException

The attribute is not present, or the name is invalid.

Implemented in IT_Reflect::ComplexTypeImpl.
