Class ParameterTemplate

java.lang.Object

org.apache.openjpa.lib.util.ParameterTemplate

public class ParameterTemplate
extends Object

A template that allows parameter substitutions. Parameters should be placed in the template in the form ${param-name}. Use the setParameter(java.lang.String, java.lang.Object) method to set the parameter values, which will be substituted into the template on calls to write(java.io.OutputStream) and toString(). If a parameter is encountered that hasn't been set, then the parameter key is used to lookup the corresponding System property.
