Detailed Description

template<typename PlaceholderT, unsigned int SizeV = POCO_SMALL_OBJECT_SIZE>
union Poco::Placeholder< PlaceholderT, SizeV >

ValueHolder union (used by Poco::Any and Poco::Dynamic::Var for small object optimization, when enabled).

If Holder<Type> fits into POCO_SMALL_OBJECT_SIZE bytes of storage, it will be placement-new-allocated into the local buffer (i.e. there will be no heap-allocation). The local buffer size is one byte larger - [POCO_SMALL_OBJECT_SIZE + 1], additional byte value indicating where the object was allocated (0 => heap, 1 => local).
