Description
Convert a value to the given Java Class. Most of
the time Oddjob's own automatic conversions are fine for setting
job properties but occasionally it can be useful to force a conversion
to a different type.
This type uses Oddjob's internal converters itself to perform the
conversion.
The is
property can provide direct access to the converted
value. This can be useful for gaining access to a Java type from Oddjob's
wrapper types.
Example
Convert a delimited list to an array of Strings.
<oddjob id="this">
<job>
<foreach>
<values>
<convert>
<to>
<class name="[Ljava.lang.String;"/>
</to>
<value>
<value value=""grapes, red", "grapes, white", gratefruit"/>
</value>
</convert>
</values>
<configuration>
<xml>
<foreach id="loop">
<job>
<echo>${loop.current}</echo>
</job>
</foreach>
</xml>
</configuration>
</foreach>
</job>
</oddjob>
The output is:
grapes, red
grapes, white
gratefruit
Example
Demonstrate the use of the is property.
<oddjob id="this">
<job>
<sequential>
<jobs>
<variables id="vars">
<aNumber>
<convert>
<to>
<class name="java.lang.Integer"/>
</to>
<value>
<value value="42"/>
</value>
</convert>
</aNumber>
</variables>
<echo>${vars.aNumber}
${vars.aNumber.class}
${vars.aNumber.value}
${vars.aNumber.value.class}
${vars.aNumber.is}
${vars.aNumber.is.class}</echo>
</jobs>
</sequential>
</job>
</oddjob>
The output is:
42
class org.oddjob.arooa.types.ConvertType
42
class org.oddjob.arooa.types.ValueType
42
class java.lang.Integer
