public final class WKTKeywords
extends Static

Constant strings for the keywords used in Well Known Text (WKT) formatting. All constant values and identical to the names of the constants.

Those constants should be used for WKT only. Do not use those constants in contexts unrelated to WKT (e.g. in @XmlRootElement annotations), even if the string has the same value. It should be possible to change a keyword used in WKT formatting without affecting GML for instance.

Note: all constants in this class are static and final. The Java compiler should replace those constants by their literal values at compile time, which avoid the loading of this class at run-time.

0.6
