MappedSelect/SQLTemplate #chain and #chunk directives

Looking at the docs
<https://cayenne.apache.org/docs/4.0/cayenne-guide/#queries> for
MappedSelect/SQLTemplate I'm not clear on how to supply the parameters for
the #chain and #chunk directives from the java side. How should I structure
this data and pass it to the SQLTemplate query?

SQL:
#chain('OR' 'AND')
    #chunk($thing1) thing1  = #bind($thing1, 'INTEGER') #end
    #chunk($thing2) thing2 >= #bind($thing2, 'TIMESTAMP') #end
#end"

Java:

Map<String, Object> queryParameters = *new* HashMap<>(2);

queryParameters.put(*?*);


MappedSelect<MyEntity> query = MappedSelect.*query*(MyDataMap.
*MYQUERY_QUERYNAME*, MyEntity.*class*).params(queryParameters);



Thanks.
