Method Detail

setProperty

public static boolean setProperty(Object o,

                                  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).

Parameters:

o - The object to set a property on

name - The property name

value - The property value

Returns:

true if operation was successful

setProperty

public static boolean setProperty(Object o,
                                  String name,
                                  String value,
                                  boolean invokeSetProperty)

getProperty

public static Object getProperty(Object o,
                                 String name)

replaceProperties

public static String replaceProperties(String value,
                                       Hashtable<Object,Object> staticProp,
                                       IntrospectionUtils.PropertySource[] dynamicProp)

Replace ${NAME} with the property value.

Parameters:

value - The value

staticProp - Replacement properties

dynamicProp - Replacement properties

Returns:

the replacement value

capitalize

public static String capitalize(String name)

Reverse of Introspector.decapitalize.

Parameters:

name - The name

Returns:

the capitalized string

clear
