Visits this node. The node reports itself to the visitor with the proper runtime type.

Throws:

X extends Exception

equals

public boolean equals(Object other)

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 interface QueryModelNode

Overrides:

equals in class UnaryValueOperator

hashCode

public int hashCode()

Overrides:

hashCode in class UnaryValueOperator

clone

public IsNumeric clone()

Description copied from interface: QueryModelNode

Returns a (deep) clone of this query model node. This method recursively clones the entire node tree, starting from this nodes.

Specified by:

clone in interface QueryModelNode

Specified by:

clone in interface ValueExpr

Overrides:

clone in class UnaryValueOperator

Returns:

A deep clone of this query model node.
