Method Summary

void	accept(StateObjectVisitor visitor) Visits this StateObject by the given visitor.
protected void	addProblems(java.util.List<Problem> problems) Adds to the given list the problems that were found with the current state of this StateObject, which means there are validation issues.
EntityTypeLiteral	getExpression() Returns the actual parsed object if this StateObject representation of the JPQL query was created by parsing an existing JPQL query.
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:

parent - The parent of this state object, which cannot be null

Throws:

java.lang.NullPointerException - The given parent cannot be null

EntityTypeLiteralStateObject

public EntityTypeLiteralStateObject(StateObject parent,
                                    java.lang.String entityTypeName)

Creates a new EntityTypeLiteralStateObject.

Parameters:

parent - The parent of this state object, which cannot be null

entityTypeName - The name of the entity

Throws:

java.lang.NullPointerException - The given parent cannot be null

Method Detail

accept

public void accept(StateObjectVisitor visitor)

Visits this StateObject by the given visitor.

Parameters:

visitor - The visitor to visit this object

addProblems

protected void addProblems(java.util.List<Problem> problems)

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()

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
