question: public static LinkedHashSet < Entity > findEntites ( LinkedHashSet < Entity > matches , HashSet < Entity > checked , Entity entity , Predicate predicate ) { if ( ! checked . add ( entity ) ) { return matches ; } if ( predicate . matches ( entity ) ) { matches . add ( entity ) ; } for ( RefNode refNode : entity . getChildren ( RefNode . class ) ) { Entity e = refNode . getReference ( ) ; if ( e != null ) { findEntites ( matches , checked , e , predicate ) ; } } for ( ToManyNode toManyNode : entity . getChildren ( ToManyNode . class ) ) { for ( Entity e : toManyNode . getList ( ) ) { if ( e != null ) { findEntites ( matches , checked , e , predicate ) ; } } } return matches ; }
target:  Finds all entities by navigating the object graph from entity which match the given predicate.<br/>
