Method Detail

getChildQueries

public List<Query> getChildQueries()

Description copied from class: Query

Returns all the children of the query in question. The returned List is provided as a copy - changes made to it do not impact the originating Query object in any way.

Specified by:

getChildQueries in class Query

replaceChildQuery

public boolean replaceChildQuery(Query toReplace,
                                 Query replacement)

Description copied from class: Query

Swap 'replacement' in as a replacement, if 'toReplace' is currently a child of this Query object. Because a tree of Query objects might conceivably have repeated clauses, this method is implemented to test 'toReplace' using reference-equality instead of value-equality.

Specified by:

replaceChildQuery in class Query

Returns:

true if a replacement was made, false otherwise.
