java.lang.Objectorg.eclipse.persistence.jpa.jpql.model.query.AbstractStateObject
org.eclipse.persistence.jpa.jpql.model.query.CollectionExpressionStateObject
public final class CollectionExpressionStateObject
This StateObject is a temporary object used to store a list of StateObjects. Those objects are not parented. StateObjectVisitor is not aware of this
object either, to visit it, the visitor will be notified via reflection, see AbstractStateObject.acceptUnknownVisitor(StateObjectVisitor).
CollectionExpression| Constructor Summary | |
|---|---|
CollectionExpressionStateObject(StateObject parent,
java.util.List<? extends StateObject> items)
Creates a new CollectionExpressionStateObject. |
|
| Method Summary | |
|---|---|
void |
accept(StateObjectVisitor visitor)
Visits this StateObject by the given visitor. |
protected void |
addChildren(java.util.List<StateObject> children)
Adds the children of this StateObject to the given list. |
protected boolean |
areChildrenEquivalent(CollectionExpressionStateObject stateObject)
Determines whether the children of this StateObject are equivalent to the children
of the given one, i.e. the information of the StateObjects is the same. |
CollectionExpression |
getExpression()
Returns the actual parsed object if this StateObject representation of the JPQL query
was created by parsing an existing JPQL query. |
boolean |
isEquivalent(StateObject stateObject)
Determines whether the given StateObject is equivalent to this one, i.e. the
information of both StateObject is the same. |
void |
setExpression(CollectionExpression 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. |
protected void |
toTextInternal(java.lang.Appendable writer)
Prints out a string representation of this StateObject, which should not be used to
define a true string representation of a JPQL query but should be used for
debugging purposes. |

public CollectionExpressionStateObject(StateObject parent,
java.util.List<? extends StateObject> items)
CollectionExpressionStateObject.
parent - The parent of this state object, which cannot be nullitems - The list of children owned by this state object
java.lang.NullPointerException - The given parent cannot be null| Method Detail |
|---|
public void accept(StateObjectVisitor visitor)
StateObject by the given visitor.
visitor - The visitor to visit this objectprotected void addChildren(java.util.List<StateObject> children)
StateObject to the given list.
addChildren in class AbstractStateObjectchildren - The list used to store the childrenprotected boolean areChildrenEquivalent(CollectionExpressionStateObject stateObject)
StateObject are equivalent to the children
of the given one, i.e. the information of the StateObjects is the same.
stateObject - The StateObject to compare its children to this one's children
true if both have equivalent children; false otherwisepublic CollectionExpression getExpression()
StateObject representation of the JPQL query
was created by parsing an existing JPQL query.
getExpression in interface StateObjectgetExpression in class AbstractStateObjectStateObject
or null when the JPQL query is manually created (i.e. not from a string)public boolean isEquivalent(StateObject stateObject)
StateObject is equivalent to this one, i.e. the
information of both StateObject is the same.
isEquivalent in interface StateObjectisEquivalent in class AbstractStateObjectstateObject - The StateObject to compare its content to this one
true if both object are equivalent; false otherwisepublic void setExpression(CollectionExpression expression)
parsed object object, which should only be
done when this object is instantiated during the conversion of a parsed JPQL query into
StateObjects.
expression - The parsed object representing a collection
expression
protected void toTextInternal(java.lang.Appendable writer)
throws java.io.IOException
StateObject, which should not be used to
define a true string representation of a JPQL query but should be used for
debugging purposes.
toTextInternal in class AbstractStateObjectwriter - The writer used to print out the string representation
java.io.IOException - This should never happens, it is only required because Appendable
is used instead of any concrete class
