type SimpleTileParser ¶
type SimpleTileParser struct {
TileParser
// contains filtered or unexported fields
}
SimpleTileParse is an implementation of the TileParser interface. It uses a simple positional regular expression to match tile requests and determine which to return from a given MBTiles database:
`\/([^\/]+)\/(\d+)\/(\d+)\/(\d+)\.(\w+)$`
Where: $1 is the name of the (MBTiles database) layer to read data from $2 is the Z value of the tile request $3 is the X value of the tile request $4 is the Y value of the tile request $5 is the mime-type extension for the tile request. Fully-qualified content-type values for file extensions are mapped using the aaronland/go-mimetypes package.
func (*SimpleTileParser) Parse ¶
func (p *SimpleTileParser) Parse(path string) (*TileRequest, error)
Parse a URI path in to a *TileRequest.
type TileParser ¶
type TileParser interface {
// Parse takes a URI path as its input and returns a *TileRequest instance.
Parse(string) (*TileRequest, error)
}
TileParser is an interface for parsing URI paths in to *TileRequest instances.
func NewSimpleTileParser ¶
func NewSimpleTileParser() (TileParser, error)
Return a new SimpleTileParser instance.
type TileRequest ¶
type TileRequest struct {
// Tile is the underlying *tilepack.Tile instance where tile data is stored
Tile *tilepack.Tile
// Layer is the name of the MBTiles to read from
Layer string
// ContentType is the mime-type of the data to return
ContentType string
}
TileRequest provides a simple struct encapsulating the specific details of a tile request.
func (*TileRequest) String ¶
func (t *TileRequest) String() string
String returns a relative URI path for the TileRequest instance.
