public abstract class AbstractConstraint extends PgStatement implements IConstraint, ISearchPath
Abstract base class for database table constraints. Provides common functionality for constraints across different database types including primary keys, foreign keys, unique constraints, and check constraints.

  • Method Details

    • getStatementType

      public DbObjType getStatementType()
      Description copied from interface: IStatement
      Gets the type of this database object.
      Specified by:
      getStatementType in interface IStatement
      Returns:
      the database object type

    • getColumns

      public Collection<String> getColumns()
      Description copied from interface: IConstraint
      Gets the columns involved in this constraint.
      Specified by:
      getColumns in interface IConstraint
      Returns:
      a collection of column names

    • containsColumn

      public boolean containsColumn(String name)
      Description copied from interface: IConstraint
      Checks if this constraint involves the specified column.
      Specified by:
      containsColumn in interface IConstraint
      Parameters:
      name - the column name to check
      Returns:
      true if the column is part of this constraint

    • isNotValid

      public boolean isNotValid()

    • setNotValid

      public void setNotValid(boolean notValid)

    • getLocation

      public PgObjLocation getLocation()
      Description copied from class: PgStatement
      Gets the location information for this statement.
      Overrides:
      getLocation in class PgStatement
      Returns:
