Definition at line 300 of file type_info.hpp.

From() [1/2]

template<typename T>

constexpr TypeIndex helios::utils::TypeIndex::From ( )

inlinestaticnodiscardconstexprnoexcept

Constructs a TypeIndex from a type T.

Template Parameters

T	The type to construct the TypeIndex for

Returns

TypeIndex representing the type T

Definition at line 268 of file type_info.hpp.

From() [2/2]

template<typename T>

constexpr TypeIndex helios::utils::TypeIndex::From ( const T & )

inlinestaticnodiscardconstexprnoexcept

Constructs a TypeIndex from an instance of type T.

Template Parameters

T	The type of the instance

Parameters

instance

The instance to construct the TypeIndex from (unused)

Returns

TypeIndex representing the type of the instance

Definition at line 279 of file type_info.hpp.

FromHash()

constexpr TypeIndex helios::utils::TypeIndex::FromHash ( size_t hash )

inlinestaticnodiscardconstexprnoexcept

Constructs a TypeIndex from a precomputed hash value.

Parameters

hash	Type hash value

Returns

TypeIndex with the given hash

Definition at line 289 of file type_info.hpp.

Hash()

size_t helios::utils::TypeIndex::Hash ( ) const

inlinenodiscardconstexprnoexcept

Retrieves the hash value associated with this TypeIndex.

Returns

Hash value or 0 if this TypeIndex is empty
