/** \class ContextFactory
|
|
* \brief ContextFactory avoids the duplicated LDContext of the same file.
|
|
*
|
|
* MCLinker is designed for efficient memory usage. Because user can give
|
|
* MCLinker the same input file many times on the command line, MCLinker must
|
|
* avoid opening identical file twice.
|
|
*
|
|
* ContextFactory is the guard to prevent redundant opening. MCLinker does not
|
|
* create LDContext directly. Instead, it creates LDContext by ContextFactory.
|
|
* ContextFactory returns the identical reference of LDContext if it's openend.
|
|
*

* @see LDContext

* @see UniqueGCFactoryBase
