Member Function Documentation

override ISqlNode Deveel.Data.Sql.Parser.ColumnConstraintNode.OnChildNode ( ISqlNode  node )

inlineprotectedvirtual

During the initialization of the node from the parser, this method is called for every child node added to ChildNodes

Parameters

node	The node being added to the list of children.

Returns

Returns a normalized version of the child node, or the node itself.

Reimplemented from Deveel.Data.Sql.Parser.SqlNode.
