callSetter

public static boolean callSetter(java.lang.Object obj,
                                 java.lang.String property,
                                 java.lang.Object value)

Find a setter method for the give object's property and try to call it. No exceptions are thrown. You typically call this method because either you are sure no exceptions will be thrown, or to silently ignore any that may be thrown. This will also find a setter that accepts an interface that the value implements. This is still not very effcient and should only be called if performance is not of an issue. You can check the return value to see if the call was seuccessful or not.

Parameters:

obj - Object to receive the call

property - property name (without set. First letter will be capitalized)

value - Value of the property.

Returns:
