Class MetricDisplayTag

java.lang.Object

javax.servlet.jsp.tagext.TagSupport

org.rhq.enterprise.gui.legacy.taglib.MetricDisplayTag

All Implemented Interfaces:

Serializable, javax.servlet.jsp.tagext.IterationTag, javax.servlet.jsp.tagext.JspTag, javax.servlet.jsp.tagext.Tag

public class MetricDisplayTag
extends javax.servlet.jsp.tagext.TagSupport

This is a locale aware tag for displaying metrics and units. Suppose you have a metricDisplaySummary.setMin(9234289) and metricDisplaySummary.setUnit("bytes") set in the bean, this tag allows you to say: and get this output: 9,018 KB This class assumes that any re-scaling of the metric value and unit string as well as any localization of the unit string was performed prior to the data being parameterized for this tag. To assure that the locale of the unit string agrees with the locale of the metric, use the jakarta-struts key org.apache.struts.Globals.LOCALE_KEY
