Detailed Description

This interface represents collections.

All collections are derived from this interface which exposes a generic way to access the data via a key-value or index-value approach. Collections represent an ordered sequence of values. Collections may be typed (all values are of the same type) or untyped.

See Types for description of the type system.

In general, the sets of keys is fixed (additional methods on specific interfaces might insert new keys, e.g., mi::IMap::insert()) and type-specific.

Note that the interface pointers returned from all variants of get_value() are not distinct copies of the values stored inside the collection, but represent the value actually stored in the collection. It is not specified whether the methods set_value() copy the value in their argument or not.

Member Function Documentation

 get_key()

virtual const char * mi::IData_collection::get_key ( Size  index) const
pure virtual

Returns the key corresponding to index.

Returns
The key, or NULL in case of failure.

 get_length()

virtual Size mi::IData_collection::get_length ( ) const
pure virtual

Returns the number of values.

Implemented in mi::IArray, mi::ICompound, and mi::IMap.

 get_value() [1/8]

template<class T>
T * mi::IData_collection::get_value ( const char *  key)
inline

Returns the value for key key.

Note
If a literal 0 is passed for key, the call is ambiguous. You need to explicitly cast the argument to const char*.

This templated member function is a wrapper of the non-template variant for the user's convenience. It eliminates the need to call mi::base::IInterface::get_interface(const Uuid&) on the returned pointer, since the return type already is a pointer to the type T specified as template parameter.

Template Parameters
TThe interface type of the element to return.

 get_value() [2/8]

template<class T>
const T * mi::IData_collection::get_value ( const char *  key) const
inline

Returns the value for key key.

Note
If a literal 0 is passed for key, the call is ambiguous. You need to explicitly cast the argument to const char*.

This templated member function is a wrapper of the non-template variant for the user's convenience. It eliminates the need to call mi::base::IInterface::get_interface(const Uuid&) on the returned pointer, since the return type already is a pointer to the type T specified as template parameter.

Template Parameters
TThe interface type of the element to return.

 get_value() [3/8]

virtual const base::IInterface * mi::IData_collection::get_value ( const char *  key) const
