value
String value
Attribute name.Default Name
If this value is omitted, the default name is inferred from the field/method name. First, if this is a method and the name starts with "set", then "set" will be trimmed off.
Then names are tokenized according to the camel case word separator, then tokens are combined with '-', then finally the whole thing is converted to the lower case.
Therefore, for example, a field name "httpBufferSize" would yield "http-buffer-size", and a method name "setThreadCount" would yield "thread-count"
- Default:
- ""

reference
boolean reference
Indicates that this property is a reference to another configured inhabitant. SeeElement.reference()
for more details of the semantics.When a reference property is a collection/array, then the key values are separated by ',' with surrounding whitespaces ignored. That is, it can be things like " foo , bar " (which would mean the same thing as "foo,bar".)
- Default:
- false
