Method Details

accept

public void accept(StateObjectVisitor visitor)

Description copied from interface: StateObject

Visits this StateObject by the given visitor.

Parameters:

visitor - The visitor to visit this object

addProblems

protected void addProblems(List<Problem> problems)

Description copied from class: AbstractStateObject

Adds to the given list the problems that were found with the current state of this StateObject, which means there are validation issues.

Overrides:

addProblems in class AbstractStateObject

Parameters:

problems - The list to which the problems are added

getExpression

public EntityTypeLiteral getExpression()

Description copied from interface: StateObject

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 AbstractStateObject

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)

setExpression

public void setExpression(EntityTypeLiteral expression)

Keeps a reference of the parsed object object, which should only be done when this object is instantiated during the conversion of a parsed JPQL query into StateObjects.

Parameters:

expression - The parsed object representing an entity type literal
