|
|
static |
Returns the current CartoType build number as a string.
◆ description()

|
) |
| |
|
static |
Gets the distance from a line of points (if aPolygon is false) or a polygon (if aPolygon is true) to the point (aPointX,aPointY) and puts the nearest point in the line or polygon in aNearestPoint.

aLat2 |
|
) |
| |
|
static |
Gets the great-circle distance in meters between (aLong1,aLat1) and (aLong2,aLat2). This function uses the WGS84 ellipsoid.

) |
| |
|
static |
Gets the length of a line, in meters, defined by points of latitude (y) and longitude (x), using great-circle distances.

) |
| |
|
static |
Sets a named attribute, treating a string as a set of map object attributes of the form label|key1=value1|key2=value2| ... |keyN=valueN, where | is character code 0, An empty or zero-length name sets the label. An empty or zero-length value deletes a name-value pair. Any of aString, aKey or aValue may be null. Returns the new string, with the attribute set.

◆ version()
| static native String com.cartotype.Util.version |
( |
| ) |
|
|
static |
Returns the current CartoType version as a string of the form MAJOR.MINOR.
