Member Function Documentation

attach()

void openswmmvis::ExtensionLayerBridge::Data::attach ( OpenSWMMVisLayer *  layer, bool  announce  )

inline

Wire a new attachment, optionally reporting its committed insertion.

Parameters

[in]	layer	Borrowed newly attached native layer.
[in]	announce	False while constructing the initial tracker.

available()

bool openswmmvis::ExtensionLayerBridge::Data::available ( ) const

inline

Verify that native state remains usable for an ordinary observation.

Returns

True while the model window/canvas remain available and not closing.

Here is the caller graph for this function:

detach()

void openswmmvis::ExtensionLayerBridge::Data::detach ( OpenSWMMVisLayer *  layer )

inline

Disconnect and retire a membership before reporting historical removal.

Parameters

[in]

layer

Non-dereferenced native identity, possibly already destroyed.

Here is the call graph for this function:

Here is the caller graph for this function:

entry()

Entry * openswmmvis::ExtensionLayerBridge::Data::entry ( OpenSWMMVisLayer *  key )

inline

Resolve one tracked and currently attached native identity.

Parameters

[in]

key

Non-dereferenced native pointer identity.

Returns

Current entry or null after removal/destruction/window close.

Here is the call graph for this function:

Here is the caller graph for this function:

order()

QList< QUuid > openswmmvis::ExtensionLayerBridge::Data::order ( ) const

inline

Copy tracked top-level attachment order without inventing identities.

Returns

Current bottom-to-top runtime identities, excluding unavailable pointers.

Here is the caller graph for this function:

publish()

void openswmmvis::ExtensionLayerBridge::Data::publish ( OpenSWMMVisLayer *  key, ViewEventKind  kind, const QStringList &  keys = {}  )

inline

Send one owning observation after checking current attachment membership.

Parameters

[in]	key	Tracked native identity.
[in]	kind	Semantic invalidation reason.
[in]	keys	Optional bounded semantic child identities.

Here is the caller graph for this function:

watch()

template<class Sender , class Signal , class Callback >

void openswmmvis::ExtensionLayerBridge::Data::watch ( Entry &  current, Sender *  sender, Signal  signal, Callback  callback  )

inline

Attach one native signal to this membership's managed connection list.

Template Parameters

Sender	Native QObject type.
Signal	Typed native member-signal pointer.
Callback	Zero-argument semantic observer.

Parameters

[in,out]	current	Owning membership record.
[in]	sender	Borrowed required native signal source.
[in]	signal	Typed native signal.
[in]	callback	GUI-thread receiver action.

Here is the caller graph for this function:

watchSublayers()

void openswmmvis::ExtensionLayerBridge::Data::watchSublayers ( OpenSWMMVisLayer *  key )

inline

Rebind authored sublayer observers after structural changes.

Parameters

[in]

key

Tracked native attachment identity.

Note

Dynamic invalidation alone produces no event unless authored metadata changed.
