Member Function Documentation

all_changed()

bool all_changed ( ) const

noexcept

Whether the whole layer changed (then changed() is not meaningful).

changed()

const std::vector< NavCelId > & changed ( ) const

noexcept

Cells changed one by one since the last clear_changes(), in order of first change.

clear_changes()

void clear_changes

(

)

const

Forget the recorded changes (call it once every consumer has seen them).

clone()

virtual std::shared_ptr< LayerViewBase > clone ( ) const

pure virtual

Independent copy of this layer (data, name, type, cached hash and pending changes).

Implemented in LayerView< T >, and LayerView< T >.

content_hash()

virtual std::uint64_t content_hash ( ) const

pure virtual

Return 64-bit content hash (cached; recomputed lazily).

Implemented in LayerView< T >, and LayerView< T >.

has_changes()

bool has_changes ( ) const

noexcept

mark_all_changed()

void mark_all_changed ( ) const

noexcept

Record that the whole layer changed.

mark_changed()

void mark_changed

(

NavCelId

cid

)

const

Record that cell cid changed (deduplicated).

mark_dirty()

void mark_dirty ( ) const

noexcept

Mark content dirty (forces hash recompute on next query).

name()

virtual const std::string & name ( ) const

pure virtual

Returns

Layer name (unique within the registry).

Implemented in LayerView< T >, and LayerView< T >.

size()

virtual size_t size ( ) const

pure virtual

Returns

Number of items (= number of NavCels).

Implemented in LayerView< T >, and LayerView< T >.

type()

virtual LayerType type ( ) const

pure virtual

Returns

Type tag of the underlying storage.

Implemented in LayerView< T >, and LayerView< T >.
