Member Function Documentation

getConfig()

template<typename ConfigType, typename ValueType>

const ValueType & ml::Manifest::getConfig ( ConfigType config )

staticinherited

Retrieve a typed configuration value by enum key.

Looks up the value previously registered via set(key, value) where value was not a file path. Throws if the key has not been registered.

Template Parameters

ConfigType	An enum type declared inside a Manifest subclass.
ValueType	The type of the stored value (e.g., int, float, std::string).

Parameters

config

The specific enum value to look up.

Returns

Const reference to the registered configuration value.

getFilepath()

template<typename Asset>

const std::string & ml::Manifest::getFilepath ( const Asset & asset )

staticinherited

Retrieve the file path registered for an asset enum value.

Looks up the path previously registered via set(key, filepath). Throws std::out_of_range if the key has not been registered.

Template Parameters

Asset

An enum type declared inside a Manifest subclass.

Parameters

asset

The specific enum value to look up.

Returns

Const reference to the registered file path string.

set() [1/4]

template<typename E, typename V, typename... Args>

void ml::Manifest::set ( E key, V && value, Args &&... args )

staticprotectedinherited

Register multiple key-value pairs in one call.

Variadic overload that expands to successive set() calls. Useful for batch registration in the inline static initializer:

set(Images::Background, "assets/bg.png",
    Images::Button,     "assets/btn.png",
    Fonts::Main,        "assets/main.ttf");

Template Parameters

E	First key type.
V	First value type.
Args	Remaining key-value pairs.

set() [2/4]

template<typename EnumType>

void ml::Manifest::set ( EnumType key, const char * filepath )

staticprotectedinherited

Register an asset file path.

Associates key with a file path. The path is later retrieved by ResourceManager when loading the asset.

Template Parameters

EnumType

Enum type of the key (inferred).

Parameters

key	The enum value to register.
filepath	Null-terminated path to the asset file.

set() [3/4]

template<typename EnumType>

void ml::Manifest::set ( EnumType key, std::string value )

staticprotectedinherited

Register a string configuration value.

Associates key with a std::string config value. Distinct from the file-path overload — an explicit std::string signals that this is configuration data, not a resource path.

Template Parameters

EnumType

Enum type of the key (inferred).

Parameters

key	The enum value to register.
value	The string configuration value.

set() [4/4]

template<typename EnumType, typename ValueType>

std::enable_if_t< !std::is_same_v< std::decay_t< ValueType >, const char * > &&!std::is_same_v< std::decay_t< ValueType >, std::string > > ml::Manifest::set ( EnumType key, ValueType && value )

staticprotectedinherited

Register a typed configuration value (int, float, bool, etc.).

Enabled for any ValueType that is not const char* or std::string, routing numeric and boolean config values into their own type-indexed storage.

Template Parameters

EnumType	Enum type of the key (inferred).
ValueType	Type of the configuration value (inferred).

Parameters

key	The enum value to register.
value	The configuration value.
