JPQLのpath_expressionを表します．

JPQLの詳細はJPA仕様書「4.14 BNF」を参照してください．

 single_valued_path_expression ::=
     state_field_path_expression | single_valued_association_path_expression
 
 state_field_path_expression ::=
     {identification_variable | single_valued_association_path_expression}.state_field
 
 single_valued_association_path_expression ::=
     identification_variable.{single_valued_association_field.}*single_valued_association_field
 
 collection_valued_path_expression ::=
     identification_variable.{single_valued_association_field.}*collection_valued_association_field
