Detailed Description

An index into a data container, referring to a particular data object. Indices may be reused for new data objects, if old objects were deleted.

Constructor & Destructor Documentation

UN_DataIndex::UN_DataIndex ( ValueType  value = INVALID_NUMBER )

inlineexplicit

Definition at line 147 of file UN_Types.h.

UN_DataIndex::UN_DataIndex ( UN_DataSize  size )

inlineexplicit

For past-end array index.

Definition at line 151 of file UN_Types.h.

UN_DataIndex::UN_DataIndex ( exint  value )

inlineexplicit

An exint is used for indexing into UT_Array, and UN_DataIndex represents such index, so these types should be interchangeable. Thus providing a constructor from exint.

Member Function Documentation

void UN_DataIndex::clear ( void  )

inline

Resets the index to an invalid value.

Definition at line 162 of file UN_Types.h.

UN_DataIndex::operator exint ( ) const

inline

Implicit cast to exint for indexing into arrays (eg, UT_Array).
