Method Detail

• accept

  public void accept​(StateObjectVisitor visitor)

  Visits this StateObject by the given visitor.

  Parameters:

  visitor - The visitor to visit this object

• getManagedType

  public IManagedType getManagedType​(StateObject stateObject)

  Returns the IManagedType for the given identification variable. The search does not traverse up the query hierarchy if this declaration is for a subquery.

  SELECT e FROM Department d JOIN KEY(d.employees).addresses a

  In the above query, the managed type associated with the identification variable:

  • d is "Department"
  • a is "Address"

  Parameters:

  stateObject - The StateObject that should be an simple identification variable or an encapsulated identification variable with the identifier KEY or VALUE

  Returns:

  The IManagedType representing the domain object declared by the given identification variable

• getParent

  public SimpleFromClauseStateObject getParent()

  Returns the parent of this StateObject.

  Specified by:

  getParent in interface StateObject

  Overrides:

  getParent in class AbstractIdentificationVariableDeclarationStateObject

  Returns:

  Returns the parent of this StateObject, which is null only when this is the root of the hierarchy

• getPath

  public String getPath()

  Returns the string representation of the path expression, which is either a singled-valued object field or a collection-valued path expression.

  Returns:

  The path expression, which is never null

• getRangeVariableDeclaration

  public DerivedPathVariableDeclarationStateObject getRangeVariableDeclaration()

  Returns the StateObject representing the range variable declaration portion.

  Overrides:

  getRangeVariableDeclaration in class AbstractIdentificationVariableDeclarationStateObject

  Returns:

  The concrete instance

• getRootStateObject

  public CollectionValuedPathExpressionStateObject getRootStateObject()

  Returns the StateObject representing the "root" for objects which may not be reachable by navigation.

  Overrides:

  getRootStateObject in class AbstractIdentificationVariableDeclarationStateObject

  Returns:

  The StateObject representing one of the possible valid "root"

• items

  public ListIterable<JoinStateObject> items()

  Returns an ListIterable over the children.

  Specified by:

  items in interface ListHolderStateObject<JoinStateObject>

  Overrides:

  items in class AbstractListHolderStateObject<JoinStateObject>

  Returns:

  An ListIterable that is iterating over the children
