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 DerivedPathIdentificationVariableDeclarationStateObject getParent()

  Returns the parent of this StateObject.

  Specified by:

  getParent in interface StateObject

  Overrides:

  getParent in class AbstractStateObject

  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. If the identification variable is virtual, then it is not part of the result.

  Returns:

  The path expression, which is never null

• getRootPath

  public String getRootPath()

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

  Specified by:

  getRootPath in class AbstractRangeVariableDeclarationStateObject

  Returns:

  The "root" object

• getRootStateObject

  The StateObject, which is never null

• setRootPath

  public void setRootPath​(String path)

  Sets the "root" object for objects which may not be reachable by navigation.

  Specified by:
