Element Detail

value

public abstract java.lang.String value

The default value for this parameter, specified as a string value that can be used in an initializer. For example, it could be "1.0" for a parameter of type double. An empty string can be used to indicate the default value for the parameter of this type, so @Default("") would indicate 0.0 for a parameter of type double or null for a parameter of type String.

Note: for parameters of type String, it is easy to forget the quotes around a string literal. A string parameter whose default is the empty string would be specified like this:
@Default("\"\"") name.
