Method Detail

itrValueComparisonExpression

protected QueryExpression itrValueComparisonExpression(ValueComparisonExpression q,
                                           Path context)

Description copied from class: QueryIterator

Default behavior is to return q. Override the method if more processing is needed. Return a new QueryExpression object if this clause is to be modified.

Overrides:

itrValueComparisonExpression in class QueryIterator

itrFieldComparisonExpression

protected QueryExpression itrFieldComparisonExpression(FieldComparisonExpression q,
                                           Path context)

Description copied from class: QueryIterator

Default behavior is to return q. Override the method if more processing is needed. Return a new QueryExpression object if this clause is to be modified.

Overrides:

itrFieldComparisonExpression in class QueryIterator

itrRegexMatchExpression

protected QueryExpression itrRegexMatchExpression(RegexMatchExpression q,
                                      Path context)

Description copied from class: QueryIterator

Default behavior is to return q. Override the method if more processing is needed. Return a new QueryExpression object if this clause is to be modified.

Overrides:

itrRegexMatchExpression in class QueryIterator

itrNaryValueRelationalExpression

protected QueryExpression itrNaryValueRelationalExpression(NaryValueRelationalExpression q,
                                               Path context)

Description copied from class: QueryIterator

Default behavior is to return q. Override the method if more processing is needed. Return a new QueryExpression object if this clause is to be modified.

Overrides:

itrNaryValueRelationalExpression in class QueryIterator

itrNaryFieldRelationalExpression

protected QueryExpression itrNaryFieldRelationalExpression(NaryFieldRelationalExpression q,
                                               Path context)

Description copied from class: QueryIterator

Default behavior is to return q. Override the method if more processing is needed. Return a new QueryExpression object if this clause is to be modified.

Overrides:

itrNaryFieldRelationalExpression in class QueryIterator

itrArrayContainsExpression

protected QueryExpression itrArrayContainsExpression(ArrayContainsExpression q,
                                         Path context)

Description copied from class: QueryIterator

Default behavior is to return q. Override the method if more processing is needed. Return a new QueryExpression object if this clause is to be modified.

Overrides:

itrArrayContainsExpression in class QueryIterator

itrArrayMatchExpression

protected QueryExpression itrArrayMatchExpression(ArrayMatchExpression q,
                                      Path context)

Description copied from class: QueryIterator

Default behavior is to recursively iterate the nested query. If nested processing returns an object different from the original nested query, this method creates a new array match expression using the new query expression, and returns that.

Overrides:

itrArrayMatchExpression in class QueryIterator
