Column APIs can represent a full constraint or a partial constraint, aligning with java.sql.DatabaseMetaData . author:    Abe White Constructor Summary public   LocalConstraint()      Default constructor. public   LocalConstraint(String name, Table table)      Constructor. Method Summary public  void addColumn(Column col)      Add a column to the constraint. public  boolean columnsMatch(Column[] ocols)      Return true if the given columns match the columns of this constraint. public  boolean containsColumn(Column col)      Return true if the pk includes the given column. public  void derefColumns()      Deref all columns in this constraint. protected  boolean equalsLocalConstraint(LocalConstraint lc)      Return true if the columns of this constraint matches that of the given one. public  Column[] getColumns()      Return all the columns the constraint spans. public  void refColumns()      Ref all columns in this constraint.  void remove()      Called when the constraint is removed from its table. public  boolean removeColumn(Column col)      Remove a column from the constraint. public  void setColumns(Column[] cols)      Set the columns the constraint spans. Constructor Detail LocalConstraint public LocalConstraint()(Code) Default constructor. LocalConstraint public LocalConstraint(String name, Table table)(Code) Constructor. Parameters:   name - the name of the constraint, if any Parameters:   table - the table of the constraint Method Detail addColumn public void addColumn(Column col)(Code) Add a column to the constraint. columnsMatch public boolean columnsMatch(Column[] ocols)(Code) Return true if the given columns match the columns of this constraint. containsColumn public boolean containsColumn(Column col)(Code) Return true if the pk includes the given column. derefColumns public void derefColumns()(Code) Deref all columns in this constraint. equalsLocalConstraint protected boolean equalsLocalConstraint(LocalConstraint lc)(Code) Return true if the columns of this constraint matches that of the given one. The constraints are not compared on name. getColumns public Column[] getColumns()(Code) Return all the columns the constraint spans. refColumns public void refColumns()(Code) Ref all columns in this constraint. remove void remove()(Code) Called when the constraint is removed from its table. removeColumn public boolean removeColumn(Column col)(Code) Remove a column from the constraint. true if the column was removed, false if not part of theprimary key setColumns public void setColumns(Column[] cols)(Code) Set the columns the constraint spans.
