Object

gudusoft.gsqlparser.dlineage.dataflow.model.SqllrSnapshot.Node

Enclosing class:

SqllrSnapshot

public static final class SqllrSnapshot.Node
extends Object

A node of the runtime model: a table, view, variable, result set, function, column, relation-rows pseudo column, process or routine, as it stood at the freeze.

Method Summary

Modifier and Type	Method and Description
String	getAlias()
SqllrSnapshot.Anchor	getAnchor() The parse tree node the model was built for (getGspObject(), the table object, ...), or null.
SqllrSnapshot.Call	getCall() For a function result set, its function or CASE, else null.
SqllrSnapshot.Anchor	getColumnAnchor() For a column, its column object, or null.
SqllrSnapshot.Anchor	getCte() For a query table over a CTE, the CTE's name, else null.
SqllrSnapshot.Position	getEnd()
List<String>	getFlags() Boolean properties that hold, by name (constant, variable, star, ...), sorted.
String	getFullName()
long	getHandle()
String	getKind() For a result set, its ResultSetClassifier.Kind name; for a table, its sub type (SubType name) or null; else null.
List<Long>	getMembers() For a table or result set, the handles of its columns at the freeze, in order.
String	getModelClass() The simple name of the model class (Table, QueryTable, ResultColumn, ...).
long	getModelId() The model's own id, or -1 when the model has none.
String	getName() The model's name, as the model holds it (a display value, never an identity).
long	getOwner() For a column, the handle of the table or result set holding it; for relation rows, of their holder.
long	getSelectStatement() For a select result set or set operation, the handle of its SELECT statement, else 0.
String	getSetOperator() For a set operation, its operator (ESetOperatorType name), else null.
SqllrSnapshot.Position	getStart() For a table column, its start position, else null.
boolean	isWildcard() For a result column, whether its column object is a wildcard, decided by the parse.
