Replace ${NAME} with the property value.

setProperty(Object o,
String name,
String value)
Find a method with the right name If found, call the method ( if param is
int or boolean we'll convert value to the right type before) - that means
you can have setDebug(1).

clazz
, all its superclasses,
interfaces and those superinterfaces are tested for a match against
the type name type
.
This is similar to instanceof
or Class.isAssignableFrom(java.lang.Class<?>)
except that the target type will not be resolved into a Class
object, which provides some security and memory benefits.clazz
- The class to test for a match.type
- The name of the type that clazz
must be.true
if the clazz
tested is an
instance of the specified type
,
false
otherwise.Copyright © 2000-2020 Apache Software Foundation. All Rights Reserved.
