The x/epochs module only exposes one keeper, the epochs keeper, which can be used to manage epochs.
Epochs Keeper
Presently only one fully-permissioned epochs keeper is exposed, which has the ability to both read and write the EpochInfo for all epochs, and to iterate over all stored epochs.
// Keeper of epoch nodule maintains collections of epochs and hooks.
type Keeper struct {
cdc codec.Codec
storeKey sdk.StoreKey
hooks types.EpochHooks
}
// Keeper is the interface for epoch module keeper
type Keeper interface {
// GetEpochInfo returns epoch info by identifier
GetEpochInfo(ctx sdk.Context, identifier string) types.EpochInfo
// SetEpochInfo set epoch info
SetEpochInfo(ctx sdk.Context, epoch types.EpochInfo)
// DeleteEpochInfo delete epoch info
DeleteEpochInfo(ctx sdk.Context, identifier string)
// IterateEpochInfo iterate through epochs
IterateEpochInfo(ctx sdk.Context, fn func(index int64, epochInfo types.EpochInfo) (stop bool))
// Get all epoch infos
AllEpochInfos(ctx sdk.Context) []types.EpochInfo
}
