Constructor & Destructor Documentation

SessionImpl()

SessionImpl ( )

protected

create a new empty session with default values.

Note

any exception arising while creating this default session will inevitably halt the system (and this is desirable)

Definition at line 41 of file session-impl.cpp.

Member Function Documentation

isValid()

bool isValid ( )

overrideprivatevirtual

Implements Session.

Definition at line 73 of file session-impl.cpp.

attach()

MObjectRef attach ( PMO const &  placement )

overrideprivatevirtual

attach a copy within the scope of the current QueryFocus point

Returns

reference to the newly created instance (placement) which was attached below the position given by current focus

Implements Session.

Definition at line 87 of file session-impl.cpp.

References SessionImpl::contents_, QueryFocus::currentPoint(), and PlacementIndex::insert().

Here is the call graph for this function:

detach()

bool detach ( PMO const &  placement )

overrideprivatevirtual

detach the denoted object (placement) from model, together with any child objects contained in the scope of this placement.

Note

as a sideeffect, the current QueryFocus is moved to the scope containing the object to be removed

Exceptions

error::Invalid

when attempting to kill root

Returns

true if actually removing something
