setProperty
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).- Parameters:
o
- The object to set a property onname
- The property namevalue
- The property value- Returns:
true

replaceProperties
public static String replaceProperties(String value, Hashtable<Object, Object> staticProp, IntrospectionUtils.PropertySource[] dynamicProp, ClassLoader classLoader) Replaces ${NAME} in the value with the value of the property 'NAME'. Replaces ${NAME:DEFAULT} with the value of the property 'NAME:DEFAULT', if the property 'NAME:DEFAULT' is not set, the expression is replaced with the value of the property 'NAME', if the property 'NAME' is not set, the expression is replaced with 'DEFAULT'. If the property is not set and there is no default the value will be returned unmodified.- Parameters:
value
- The valuestaticProp
- Replacement propertiesdynamicProp
- Replacement propertiesclassLoader
- Class loader associated with the code requesting the property- Returns:
- the replacement value

isInstance
Checks to see if the specified class is an instance of or assignable from the specified type. The classclazz
, all its superclasses, interfaces and those superinterfaces are tested for a match against the type nametype
. This is similar toinstanceof
orClass.isAssignableFrom(java.lang.Class<?>)
except that the target type will not be resolved into a Class object, which provides some security and memory benefits.- Parameters:
clazz
- The class to test for a match.type
- The name of the type thatclazz
must be.- Returns:
true
if theclazz
tested is an instance of the specifiedtype
,false
otherwise.
