Returns the tree node at the specified number.
Returns the tree node at the specified number. Numbers for each node can be found in the numberedTreeString.
Returns a string representing the arguments to this node, minus any children
Returns a string representing the arguments to this node, minus any children
Returns a 'scala code' representation of this TreeNode and its children.
Returns a 'scala code' representation of this TreeNode and its children. Intended for use
when debugging where the prettier toString function is obfuscating the actual structure. In the
case of 'pure' TreeNodes that only contain primitives and other TreeNodes, the result can be
pasted in the REPL to build an equivalent Tree.
Returns true if all its children of this query plan have been resolved.
Returns true if all its children of this query plan have been resolved.
Returns a Seq containing the result of applying a partial function to all elements in this tree on which the function is defined.
Returns a Seq containing the result of applying a partial function to all elements in this tree on which the function is defined.
Returns all of the expressions present in this query plan operator.
Returns all of the expressions present in this query plan operator.
Faster version of equality which short-circuits when two treeNodes are the same instance.
Faster version of equality which short-circuits when two treeNodes are the same instance.
We don't just override Object.Equals, as doing so prevents the scala compiler from from
generating case class equals methods
Returns a Seq by applying a function to all nodes in this tree and using the elements of the resulting collections.
Returns a Seq by applying a function to all nodes in this tree and using the elements of the resulting collections.
Runs the given function on this node and then recursively on children.
Appends the string represent of this node and its children to the given StringBuilder.
Appends the string represent of this node and its children to the given StringBuilder.
A globally unique id for this specific instance.
A globally unique id for this specific instance. Not preserved across copies.
Unlike equals, id can be used to differentiate distinct but structurally
identical branches of a tree.
Returns the set of attributes that this node takes as input from its children.
Returns the set of attributes that this node takes as input from its children.
Creates a copy of this type of tree node after a transformation.
Creates a copy of this type of tree node after a transformation. Must be overridden by child classes that have constructor arguments that are not present in the productIterator.
the new product arguments.
Returns a Seq containing the result of applying the given function to each node in this tree in a preorder traversal.
Returns a Seq containing the result of applying the given function to each node in this tree in a preorder traversal.
the function to be applied.
Returns a copy of this node where f has been applied to all the nodes children.
Returns a copy of this node where f has been applied to all the nodes children.
Returns the name of this type of TreeNode.
Returns the name of this type of TreeNode. Defaults to the class name.
Returns a string representation of the nodes in this tree, where each operator is numbered.
Args to the constructor that should be copied, but not transformed.
Args to the constructor that should be copied, but not transformed. These are appended to the transformed args automatically by makeCopy
Returns the set of attributes that are output by this node.
Returns the set of attributes that are output by this node.
Optionally resolves the given string to a NamedExpression.
Optionally resolves the given string to a
NamedExpression. The attribute is expressed as
as string in the following form: [scope].AttributeName.[nested].[fields]....
Returns true if this expression and all its children have been resolved to a specific schema and false if it is still contains any unresolved placeholders.
Returns true if this expression and all its children have been resolved to a specific schema
and false if it is still contains any unresolved placeholders. Implementations of LogicalPlan
can override this (e.g. UnresolvedRelation should
return false).
Returns true if other is the same TreeNode instance.
String representation of this node without any children
String representation of this node without any children
The arguments that should be included in the arg string.
The arguments that should be included in the arg string. Defaults to the productIterator.
Returns a copy of this node where rule has been recursively applied to the tree.
Returns a copy of this node where rule has been recursively applied to the tree.
When rule does not apply to a given node it is left unchanged.
Users should not expect a specific directionality. If a specific directionality is needed,
transformDown or transformUp should be used.
the function use to transform this nodes children
Returns the result of running transformExpressions on this node and all its children.
Returns the result of running transformExpressions on this node and all its children.
Returns a copy of this node where rule has been recursively applied to all the children of
this node.
Returns a copy of this node where rule has been recursively applied to all the children of
this node. When rule does not apply to a given node it is left unchanged.
the function used to transform this nodes children
Returns a copy of this node where rule has been recursively applied to it and all of its
children (pre-order).
Returns a copy of this node where rule has been recursively applied to it and all of its
children (pre-order). When rule does not apply to a given node it is left unchanged.
the function used to transform this nodes children
Runs transform with rule on all expressions present in this query operator.
Runs transform with rule on all expressions present in this query operator.
Users should not expect a specific directionality. If a specific directionality is needed,
transformExpressionsDown or transformExpressionsUp should be used.

Returns a copy of this node where rule has been recursively applied first to all of its
children and then itself (post-order).
Returns a copy of this node where rule has been recursively applied first to all of its
children and then itself (post-order). When rule does not apply to a given node, it is left
unchanged.
