Types ¶

type DetailsEntity ¶

type DetailsEntity struct {
	Id              uint64 `db:"id"`
	Border          string `db:"border"`
	SimpleBorder    string `db:"simple_border"`
	SimpleBorderWKB []byte `db:"simple_border_wkb"`
	TileType        uint16 `db:"tiletype"`
	DateTime        int64  `db:"datetime"`
	Enabled         bool   `db:"enabled"`
	Identifier      string `db:"identifier"`
	Scale           uint16 `db:"scale"`
}

type Storage ¶

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

func NewStorage ¶

func NewStorage(dbName string) (*Storage, error)

func (*Storage) BeginTxx ¶

func (s *Storage) BeginTxx() (*sqlx.Tx, error)

func (*Storage) Close ¶

func (s *Storage) Close()

func (*Storage) CommitTxx ¶

func (s *Storage) CommitTxx(txx *sqlx.Tx) error

func (*Storage) CreatePartitionTableIfNotExist ¶

func (s *Storage) CreatePartitionTableIfNotExist(txx *sqlx.Tx, tableName string)

func (*Storage) GenerateTableName ¶

func (s *Storage) GenerateTableName(key quadmap.QuadKey) string

GenerateTableName generates the table name that should be associated with the provided quadkey. Currently the assumption is that the table name will be associated with an ancestor of the quadkey at level 10. This is an attempt to find a sweet spot between performance and the number of tables. If the provided quadkey is already smaller than 10, then the table name will be "quadmap_high".

func (*Storage) GetAllDetails ¶

func (s *Storage) GetAllDetails() ([]DetailsEntity, error)

func (*Storage) GetDetails ¶

func (s *Storage) GetDetails(id int) (*DetailsEntity, error)

func (*Storage) GetTile ¶

func (s *Storage) GetTile(qk quadmap.QuadKey) (*TileEntity, error)

func (*Storage) HasIdentifier ¶

func (s *Storage) HasIdentifier(identifier string, tileType quadmap.TileType) bool

func (*Storage) InsertDetails ¶

func (s *Storage) InsertDetails(details DetailsEntity) (int64, error)

func (*Storage) InsertIdentifier ¶

func (s *Storage) InsertIdentifier(identifier string, tileType quadmap.TileType) error

func (*Storage) InsertTileWith ¶

func (s *Storage) InsertTileWith(txx *sqlx.Tx, tile TileEntity) error

func (*Storage) InsertTileWithTableName ¶

func (s *Storage) InsertTileWithTableName(txx *sqlx.Tx, tableName string, tile TileEntity) error

func (*Storage) SearchDetailsBetweenQuadKeys ¶

func (s *Storage) SearchDetailsBetweenQuadKeys(qk1 quadmap.QuadKey, qk2 quadmap.QuadKey, tileTypes []quadmap.TileType, includeSimpleBorder bool, limit int) ([]DetailsEntity, error)

SearchDetailsWithinQuadKey returns details for any hits within a particular QuadKey

func (*Storage) SearchDetailsWithinQuadKey ¶

func (s *Storage) SearchDetailsWithinQuadKey(qk quadmap.QuadKey, tileTypes []quadmap.TileType, includeSimpleBorder bool, limit int) ([]DetailsEntity, error)

func (*Storage) SearchQuadKeysWithinQuadKey ¶

func (s *Storage) SearchQuadKeysWithinQuadKey(qk quadmap.QuadKey) ([]int64, error)

func (*Storage) UpdateDetails ¶

func (s *Storage) UpdateDetails(details DetailsEntity) error

type TileEntity ¶

type TileEntity struct {
	QuadKey     quadmap.QuadKey `db:"quadkey"`
	TileType    uint16          `db:"tiletype"`
	Full        bool            `db:"full"`
	DetailsMask uint64          `db:"details_mask"`
	DetailsID   int64           `db:"details_id"`
}

Entities: TileEntity has quadkey and details mask. The details mask will indicate if there are QuadKey is NOT the primary key... but will be indexed and will be main column we search on.
