AbstractQueryModelNode() |
| Modifier and Type | Method and Description |
|---|---|
AbstractQueryModelNode |
clone()
Returns a (deep) clone of this query model node.
|
QueryModelNode |
getParentNode()
Gets the node's parent.
|
String |
getSignature()
Default implementation of
QueryModelNode.getSignature() that prints the name of the node's class. |
boolean |
isGraphPatternGroup()
indicates if the node represents the root of a graph pattern group.
|
protected boolean |
nullEquals(Object o1,
Object o2) |
void |
replaceChildNode(QueryModelNode current,
QueryModelNode replacement)
Default implementation of
QueryModelNode.replaceChildNode(QueryModelNode, QueryModelNode) that throws an
IllegalArgumentException indicating that current is not a child node of this node. |
protected <T extends QueryModelNode> |
replaceNodeInList(List<T> list,
QueryModelNode current,
QueryModelNode replacement) |
void |
replaceWith(QueryModelNode replacement)
Default implementation of
QueryModelNode.replaceWith(QueryModelNode) that throws an
IllegalArgumentException indicating that current is not a child node of this node. |
void |
setGraphPatternGroup(boolean isGraphPatternGroup)
Set the value of
GraphPatternGroupable.isGraphPatternGroup() to true or false. |
void |
setParentNode(QueryModelNode parent)
Sets the node's parent.
|
String |
toString()
Returns an indented print of the node tree, starting from this node.
|
<X extends Exception> |
visitChildren(QueryModelVisitor<X> visitor)
Dummy implementation of
QueryModelNode.visitChildren(org.eclipse.rdf4j.query.algebra.QueryModelVisitor<X>) that does nothing. |
