Method Detail

• getExpression

  public AbstractTripleEncapsulatedExpression getExpression()

  Returns the actual parsed object if this StateObject representation of the JPQL query was created by parsing an existing JPQL query.

  Specified by:

  getExpression in interface StateObject

  Overrides:

  getExpression in class AbstractEncapsulatedExpressionStateObject

  Returns:

  The parsed object when a JPQL query is parsed and converted into a StateObject or null when the JPQL query is manually created (i.e. not from a string)

• getFirst

  public StateObject getFirst()

  Returns the StateObject representing the first expression.

  Returns:

  The first encapsulated StateObject or null if none exists

• getSecond

  public StateObject getSecond()

  Returns the StateObject representing the second expression.

  Returns:

  The second encapsulated StateObject or null if none exists

• getThird

  public StateObject getThird()

  Returns the StateObject representing the third expression.

  Returns:

  The third encapsulated StateObject or null if none exists

• hasFirst

  public boolean hasFirst()

  Determines whether the StateObject representing the first encapsulated expression is present or not.

  Returns:

  true if the first StateObject is not null; false otherwise

• hasSecond

  public boolean hasSecond()

  Determines whether the StateObject representing the second encapsulated expression is present or not.

  Returns:

  true if the second StateObject is not null; false otherwise

• hasThird

  public boolean hasThird()

  Determines whether the StateObject representing the third encapsulated expression is present or not.

  Returns:

  true if the third StateObject is not null; false otherwise

• isEquivalent

  public boolean isEquivalent​(StateObject stateObject)

  Determines whether the given StateObject is equivalent to this one, i.e. the information of both StateObject is the same.

  Specified by:

  isEquivalent in interface StateObject

  Overrides:

  isEquivalent in class AbstractStateObject

  Parameters:

  stateObject - The StateObject to compare its content to this one

  Returns:

  true if both object are equivalent; false otherwise

• parseFirst

  public void parseFirst​(String jpqlFragment)

  Parses the given JPQL fragment, which will represent the first encapsulated expression.

  Parameters:

  jpqlFragment - The string representation of the first encapsulated expression to parse and to convert into a StateObject representation

• parseSecond

  public void parseSecond​(String jpqlFragment)

  Parses the given JPQL fragment, which will represent the second encapsulated expression.

  Parameters:

  jpqlFragment - The string representation of the second encapsulated expression to parse and to convert into a StateObject representation

• parseThird

  public void parseThird​(String jpqlFragment)

  Parses the given JPQL fragment, which will represent the third encapsulated expression.

  Parameters:

  jpqlFragment - The string representation of the third encapsulated expression to parse and to convert into a StateObject representation

• setFirst

  public void setFirst​(StateObject firstStateObject)

  Sets the given StateObject to represent the first encapsulated expression.

  Parameters:

  firstStateObject - The new encapsulated StateObject representing the first expression

• setSecond

  public void setSecond​(StateObject secondStateObject)

  Sets the given StateObject to represent the second encapsulated expression.

  Parameters:

  secondStateObject - The new encapsulated StateObject representing the second expression

• setThird

  public void setThird​(StateObject thirdStateObject)

  Sets the given StateObject to represent the third encapsulated expression.

  Parameters:

  thirdStateObject - The new encapsulated StateObject representing the third expression
