Method Detail
-
visit
public <X extends Exception> void visit(QueryModelVisitor<X> visitor) throws X extends Exception
Description copied from interface:QueryModelNode
Visits this node. The node reports itself to the visitor with the proper runtime type.- Throws:
X extends Exception
-
visitChildren
public <X extends Exception> void visitChildren(QueryModelVisitor<X> visitor) throws X extends Exception
Description copied from interface:QueryModelNode
Visits the children of this node. The node callsQueryModelNode.visit(QueryModelVisitor)
on all of its child nodes.- Throws:
X extends Exception
-
replaceChildNode
public void replaceChildNode(QueryModelNode current, QueryModelNode replacement)
Description copied from interface:QueryModelNode
Replaces one of the child nodes with a new node.- Parameters:
current
- The current child node.replacement
- The new child node.
-
getSignature
public String getSignature()
Description copied from class:AbstractQueryModelNode
Default implementation ofQueryModelNode.getSignature()
that prints the name of the node's class.- Specified by:
getSignature
in interfaceQueryModelNode
- Overrides:
getSignature
in classAbstractQueryModelNode
- Returns:
- The node's signature, e.g. SLICE (offset=10, limit=10).
-
equals
public boolean equals(Object obj)
Description copied from interface:QueryModelNode
Returns true if this query model node and its children are recursively equal to o and its children.- Specified by:
equals
in interfaceQueryModelNode
- Overrides:
equals
in classObject
-
getEndpointID
public String getEndpointID()
-
isLocal
public boolean isLocal()
