Detailed Description

template<class T>
struct ecsm::ID< T >

Item identifier in the LinearPool.

Template Parameters

T	type of the item in the linear pool

Identifier or index associated with individual items within the pool. Each item in the pool can be uniquely identified by its identifier, which helps in managing and referencing items.

Constructor & Destructor Documentation

ID()

template<class T >

template<class U >

constexpr ID ( ID< U > id )

inlineexplicitconstexprnoexcept

Changes the type of the identifier item.

Useful in cases where we need to cast item identifier type.

Template Parameters

U	is a new type of the identifier item

Parameters

id	item identifier in the linear pool

Member Function Documentation

operator*() [1/2]

template<class T >

uint32_t operator* ( ) const

inlinenoexcept

Returns item index + 1 in the linear pool.

Used to get internal integer index.

operator*() [2/2]

template<class T >

uint32_t & operator* ( )

inlinenoexcept

Returns reference to the item index + 1 in the linear pool.

Note

You can use it to set the identifier index value.

operator==()

template<class T >

constexpr bool operator== ( ID< T > v ) const

inlineconstexprnoexcept

Returns true if this identifier is equal to the v identifier.

Parameters

v	other identifier value

operator!=()

template<class T >

constexpr bool operator!= ( ID< T > v ) const

inlineconstexprnoexcept

Returns true if this identifier is not equal to the v identifier.

Parameters

v	other identifier value

operator<()

template<class T >

constexpr bool operator< ( ID< T > v ) const

inlineconstexprnoexcept

Returns true if this identifier is less than the v identifier.

Parameters

v	other identifier value
