Constructor Detail

ComposedSubquery

public ComposedSubquery(String[] subsections,
                        ComposedQuery cq,
                        String queryLanguage)

Make a subquery of the indicated query, from the given sections.

Parameters:

usesHQL - true if we use Hibernate to execute the query

Method Detail

deriveFrom

void deriveFrom(int n)

Derives the FROM section using the sections of the superQuery

Parameters:

n - the index of the section

concat

static void concat(String[] result,
                   String[] h1,
                   String[] h2,

                   String sep,
                   boolean paran)

Concatenates sections on the given index, with the given separator

Parameters:

result - the String array containing the result

h1 - first array of sections

h2 - second array of sections

what - the index at which we should concatenate

paran - do we want parenthesis

initKeysets

protected void initKeysets()

Initializes the keysets by adding the superquery's previousKeyset to its keyset.

Overrides:
