public class Switch extends org.apache.tools.ant.Task
Task definition for the ANT task to switch on a particular value.Usage: Task declaration in the project:
<taskdef name="switch" classname="net.sf.antcontrib.logic.Switch" />
Task calling syntax:<switch value="value" [caseinsensitive="true|false"] > <case value="val"> <property name="propname" value="propvalue" /> | <antcall target="targetname" /> | any other tasks </case> [ <default> <property name="propname" value="propvalue" /> | <antcall target="targetname" /> | any other tasks </default> ] </switch>
Attributes: value -> The value to switch on caseinsensitive -> Should we do case insensitive comparisons? (default is false) Subitems: case --> An individual case to consider, if the value that is being switched on matches to value attribute of the case, then the nested tasks will be executed. default --> The default case for when no match is found. Crude Example:<switch value="${foo}"> <case value="bar"> <echo message="The value of property foo is bar" /> </case> <case value="baz"> <echo message="The value of property foo is baz" /> </case> <default> <echo message="The value of property foo is not sensible" /> </default> </switch>
