| Method Summary | |
| public static Method | findGetMethod(Class cl, String name)
| | public static Method | findSetMethod(Class cl, String name)
| | public static Method | getMethod(Object target, String name, Object[] params)
| | public static Object | getProperty(Object target, String propName)
| | public static Class | getPropertyType(Object target, String propName)
| | public static String[] | hashtableToStrings(Hashtable table)
Ad-hoc serialization of a hashtable as a string array. | | public static boolean | matches(Class[] parms, Object[] args)
| | public static void | setObjectProperty(Object target, String name, Object value, boolean strict)
Attempts to look up a field or a "setXXX" method on the target object and
use it to set specified property. | | public static void | setProperty(Object target, String name, String value, boolean strict)
Attempts to look up a field or a "setXXX" method on the target object and
use it to set specified property. | | public static void | setProperty(Object target, Method propSetter, int propertyType, PortletRequest req, String paramName)
| | public static Hashtable | stringsToHashtable(String[] strings)
A hashtable deserialization method corresponding to
hashtableToStrings. |
| getMethod | | public static Method getMethod(Object target, String name, Object[] params) throws Exception(Code) | | Attempts to find the Method object given the target object, method
name, and the parameters
Method invocation result
Parameters:
target - Target object
Parameters:
name - Method name
exception:
Exception - Thrown if the method cannot be found |
| hashtableToStrings | | public static String[] hashtableToStrings(Hashtable table)(Code) | | Ad-hoc serialization of a hashtable as a string array. Each
hashtable entry is converted into three strings: key name,
stringified object, class name of the object.
Parameters:
table - Hashtable to be serialized Serialized hashtable |
| matches | | public static boolean matches(Class[] parms, Object[] args)(Code) | | Utility method used by getMethod to find out if the supplied
arguments array matches the type array
Parameters:
parms - A class array representing a method signature
Parameters:
args - Argument array |
| setProperty | | public static void setProperty(Object target, String name, String value, boolean strict) throws IllegalAccessException, InvocationTargetException(Code) | | Attempts to look up a field or a "setXXX" method on the target object and
use it to set specified property. If the "strict" flag is true and
this method fails to match property name with a field/method, it throws
IllegalArgumentException. The value
is converted to an object of the appropriate class based on the field type.
Currently this method does not handle array or non-primitive properties.
Parameters:
target - Target object
Parameters:
Property - name
Parameters:
String - specifying property value
Parameters:
strict - If true and a matching field/method is not found, this methodthrows IllegalAccessException.
throws:
InvocationTargetException -
throws:
IllegalAccessException - |
| stringsToHashtable | | public static Hashtable stringsToHashtable(String[] strings) throws ClassNotFoundException(Code) | | A hashtable deserialization method corresponding to
hashtableToStrings.
Parameters:
strings - A string array containing serialized hashtable Deserialized hashtable |
