If you declare an instance field with an initializer, or use a
'static {...}' block, Java will effectively copy that initializer or
block into all constructors.
For example:
@parser::members {
private Map<KeyType, ValueType> map = initMap();
}
or
@parser::members {
private Map<KeyType, ValueType> map;
static {
map = new HashMap<KeyType, ValueType>();
...
}
}
