Description copied from interface: JDBCExpression

Initialize the expression. This method should recursively initialize any sub-expressions or values. It should also cache the Joins instance containing the joins for this expression.

Specified by:

initialize in interface JDBCExpression

Overrides:

initialize in class ContainsExpression

Parameters:

pm - the persistence manager for this query

select - manage joins made in each query clause

containsCounts - map of relation paths to the number of times the paths appear in a contains() expression; used to ensure paths used for contains() within the same AND expression used different aliases
