PlacementIndex::Table Class Reference

Description

Storage and implementation backing the PlacementIndex.

• #placementTab_ is an hashtable mapping IDs to Placement + Scope
• #scopeTab_ is an reverse association serving to keep track of any scope's contents
• root scope element is stored and maintained explicitly.

always at least 1 because of root

scope_cnt()

Note

root doesn't produce an scope entry

Here is the call graph for this function:

setupRoot()

void setupRoot ( PlacementMO const &  rootDef )

inline

insert a specially configured root entry into the yet empty table.

Root is it's own scope

Definition at line 219 of file placement-index.cpp.

addEntry()

ID addEntry ( PlacementMO const &  newObj, ID  scopeID  )

inline

Store a copy of the given Placement as new instance within the index, together with the Scope this Placement belongs to.

Note

we discard the specific type info. It can be rediscovered later with the help of the pointee's vtable

Here is the call graph for this function:

resolveScopeIndexElement()

PlacementMO& resolveScopeIndexElement ( pair< PID, PID > const &  entry ) const

inlineprivate

Helper for building a scope exploring iterator for PlacementIndex: our "reverse index" (scopeTab_) tracks the contents of each scope as pairs (scopeID,elementID).

After fetching the range of matching entries, whenever the client dereferences the iterator, we have to pick up the second ID and resolve it through the main index table (placementTab_).

Returns

functor for iterator element access
