TreeType* getTree ( ) const

inline

Return a pointer to the tree associated with this accessor.

The pointer will be null only if the tree from which this accessor was constructed was subsequently deleted (which generally leaves the accessor in an unsafe state).

static bool isSafe ( )

inlinestatic

Return true if this accessor is safe, i.e. registered by the tree from which it is constructed. Un-registered accessors can in rare cases be faster because it avoids the (small) overhead of registration, but they are unsafe if the tree is modified. So unless you're an expert it is highly recommended to set IsSafe = true (which is the default).

ValueAccessorBase& operator= ( const ValueAccessorBase< TreeType, IsSafe > &  other )

TreeType& tree ( ) const

Return a reference to the tree associated with this accessor.
