Detailed Description

Base class for type-erased component storage.

Provides a common interface for storing different component types in a heterogeneous container. Each derived ComponentStorage<T> manages components of a specific type T using a sparse set for efficient operations.

Note

Not thread-safe. All operations should be performed from the main thread.

Definition at line 30 of file components_manager.hpp.

Member Function Documentation

Clear()

virtual void helios::ecs::details::ComponentStorageBase::Clear ( )

pure virtualnoexcept

Clears all components from storage.

Removes all component instances and resets internal state.

Implemented in helios::ecs::details::ComponentStorage< T >.

Contains()

virtual bool helios::ecs::details::ComponentStorageBase::Contains ( Entity  entity ) const

pure virtual

Checks if entity has a component in this storage.

Performs fast lookup to determine component presence.

Parameters

entity

Entity to check

Returns

True if entity has a component in this storage, false otherwise

Implemented in helios::ecs::details::ComponentStorage< T >.

GetTypeInfo()

virtual ComponentTypeInfo helios::ecs::details::ComponentStorageBase::GetTypeInfo ( ) const

pure virtualnoexcept

Gets type information for the component type stored.

Returns compile-time component metadata including size, alignment, etc.

Returns

ComponentTypeInfo for the stored component type

Implemented in helios::ecs::details::ComponentStorage< T >.

Remove()

virtual void helios::ecs::details::ComponentStorageBase::Remove ( Entity  entity )

pure virtual

Removes component for the specified entity.

Removes the component associated with the entity.

Warning

Triggers assertion if entity doesn't have the component.

Parameters

entity

Entity to remove component from

Implemented in helios::ecs::details::ComponentStorage< T >.

Size()

virtual size_t helios::ecs::details::ComponentStorageBase::Size ( ) const

pure virtualnoexcept

Gets the number of components in storage.

Returns count of component instances currently stored.

Returns

Number of components in storage

Implemented in helios::ecs::details::ComponentStorage< T >.

TryRemove()

virtual bool helios::ecs::details::ComponentStorageBase::TryRemove ( Entity  entity )

pure virtual

Attempts to remove component for the specified entity.

Removes the component if it exists, otherwise does nothing.

Parameters

entity

Entity to remove component from

Returns

True if component was removed, false if entity didn't have the component

Implemented in helios::ecs::details::ComponentStorage< T >.
