Class Debug

java.lang.Object

com.vividsolutions.jts.util.Debug

public class Debug
extends Object

Provides routines to simplify and localize debugging output. Debugging is controlled via a Java system property value. If the system property with the name given in DEBUG_PROPERTY_NAME (currently "jts.debug") has the value "on" or "true" debugging is enabled. Otherwise, debugging is disabled. The system property can be set by specifying the following JVM option:

 -Djts.debug=on
