Parameters:

path - the directory path

n - the northern boundary

s - the southern boundary

e - the eastern boundary

w - the western boundary

tileID - our tile identifier

TileDirectory

public TileDirectory()

Construct an untiled TileDirectory. Since this object does not have valid boundaries, it is an error to call inRegion on it

Method Detail

getPath

public java.lang.String getPath()

Return the path for this tile

a string path

getTileID

public int getTileID()

Return the tile identifier for this tile

Returns:

the tile id (-1 for untiled coverage)

toString

public java.lang.String toString()

Return a string describing ourselves

Overrides:

toString in class java.lang.Object

Returns:

a string usable as a directory path component

                        float e,
                        float w)

Figure out if our region overlaps the passed in region

Parameters:

n - the northern boundary

s - the southern boundary

e - the eastern boundary
