Types

type APIConfigStore 

type APIConfigStore struct {
	sync.RWMutex
	Initialized bool
	// contains filtered or unexported fields
}

func BuildAPIConfigStore 

func BuildAPIConfigStore() *APIConfigStore

func (*APIConfigStore) GetConfig 

func (cs *APIConfigStore) GetConfig(key string) (*prefabProto.Config, bool)

GetConfig retrieves a Config associated with the given key. It returns a pointer to the Config and a boolean value. The Config pointer is nil if the key does not exist in the store. The boolean value is true if the key exists, and false otherwise.

func (*APIConfigStore) GetContextValue 

func (cs *APIConfigStore) GetContextValue(propertyName string) (interface{}, bool)

func (*APIConfigStore) GetProjectEnvID 

func (cs *APIConfigStore) GetProjectEnvID() int64

func (*APIConfigStore) Len 

func (cs *APIConfigStore) Len() int

func (*APIConfigStore) SetConfigs 

func (cs *APIConfigStore) SetConfigs(configs []*prefabProto.Config, envID int64)

func (*APIConfigStore) SetFromConfigsProto 

func (cs *APIConfigStore) SetFromConfigsProto(configs *prefabProto.Configs)

type CompositeConfigStore 

type CompositeConfigStore struct {
	// contains filtered or unexported fields
}

CompositeConfigStore is a config store that composes multiple config stores. It attempts to find a config by key in each store in the order they were provided. The first store that contains the requested config is used, and the search stops. If no store contains the requested config, the CompositeConfigStore returns false to indicate that the config does not exist.
