question: public void andWith ( OrCondition other ) { List < AndCondition > expandedExpressionChildren = new ArrayList < AndCondition > ( ) ; for ( AndCondition otherExprTerm : other . getAndTerms ( ) ) { for ( AndCondition currentExpr : children ) { AndCondition currentAndConditionCopy = currentExpr . copy ( ) ; currentAndConditionCopy . andWith ( otherExprTerm . getTerms ( ) ) ; expandedExpressionChildren . add ( currentAndConditionCopy ) ; } } children = expandedExpressionChildren ; }
target:  Updates this OrCondition in place so that it matches vertices that satisfy the current OrCondition AND that satisfy the provided OrCondition.
