Class SystemProperty

java.lang.Object
  com.triactive.jdo.util.SystemProperty

public final class SystemProperty

extends java.lang.Object

Static methods for retrieving and system properties and converting them to various types.

These methods are very similar to others in java.lang; for example, intValue(java.lang.String, int) is nearly the same as Integer.getInteger(String,int). The main difference is that these methods log warnings for invalid property values.
