- 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>
