Class ConstraintModel

Object

gudusoft.gsqlparser.catalog.input.model.ConstraintModel

public final class ConstraintModel
extends Object

Table constraint entry. Plan §6.

type() is a string (PK / FK / UNIQUE / CHECK / NOT_NULL) so the model stays forward-compatible with vendor-specific constraint flavors.

Foreign-key targets. referencedTable() and referencedColumns() carry the FK target side and mirror TConstraint.getReferencedObject() / TConstraint.getReferencedColumnList() on the AST side. The model is permissive: both fields may be set on any constraint type, but CatalogModelValidator enforces FK-specific semantics (required target table, matching column counts, resolvable target table + columns).

referencedTable() is a single string and may carry a qualified name (e.g. "schema.table"). It is the catalog-side counterpart of TObjectName.toString().

Method Detail

builder

public static ConstraintModel.Builder builder()

name

public String name()

type

public String type()

PK / FK / UNIQUE / CHECK / NOT_NULL — string for forward compatibility.

columns

public List<String> columns()

referencedTable

public String referencedTable()

Target table for a foreign-key constraint, or null for non-FK constraints. May be a single name ("orders") or qualified ("shop.orders" / "catalog.shop.orders"). Resolution is up to the validator / runtime; the model itself does not interpret dots.

referencedColumns

public List<String> referencedColumns()

Target columns on the foreign-key referencedTable(), ordered to align positionally with columns(). Empty (never null) for non-FK constraints.

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:
