## org.apache.openjpa.jdbc.meta.strats
Class StateComparisonVersionStrategy.CustomUpdate

    java.lang.Object
      org.apache.openjpa.jdbc.sql.RowImpl
          org.apache.openjpa.jdbc.meta.strats.StateComparisonVersionStrategy.CustomUpdate

All Implemented Interfaces:
  Cloneable, Row, RowManager

Enclosing class:
  StateComparisonVersionStrategy

    public static class StateComparisonVersionStrategy.CustomUpdate

extends RowImpl
implements RowManager

Row implementation we use to pass to versionable mappings so they can set up the where conditions we need to add to update statements.

Method Detail

### getSQL

    public String getSQL()

  Return a boolean SQL expression that should be added to the WHERE clause of an UPDATE to test whether the current database record matches our stored version.

### newInstance

    protected RowImpl newInstance(Table table,
                                  int action)

  Description copied from class: `RowImpl`
  Return a new row.

  Overrides:
    `newInstance` in class `RowImpl`

### hasAutoAssignConstraints

    public boolean hasAutoAssignConstraints()

### getInserts

    public Collection getInserts()

### getUpdates

    public Collection getUpdates()

### getDeletes

    public Collection getDeletes()

### getSecondaryUpdates

    public Collection getSecondaryUpdates()

### getSecondaryDeletes

    public Collection getSecondaryDeletes()

### getAllRowUpdates

    public Collection getAllRowUpdates()

### getAllRowDeletes

    public Collection getAllRowDeletes()

### getRow

    public Row getRow(Table table,
                      int action,
                      OpenJPAStateManager sm,
                      boolean create)

  Description copied from interface: `RowManager`
  Return the row for the given table and owner object, or null if `create` is false and the row has not already been created. The action must be one of `Row.ACTION_INSERT`, `Row.ACTION_UPDATE`, `Row.ACTION_DELETE`.

  Specified by:
    `getRow` in interface `RowManager`

### getSecondaryRow

    public Row getSecondaryRow(Table table,
                               int action)

  Description copied from interface: `RowManager`
  Return a row for the given secondary table. The action must be one of `Row.ACTION_INSERT`, `Row.ACTION_UPDATE`, `Row.ACTION_DELETE`. Note that secondary rows are not considered when creating the foreign key dependency graph, with can cause constraint violations when using the `UPDATE` action. Only use this action if the secondary row does not have restrict-action foreign keys. Otherwise use both a delete and then an insert to perform the update.

  Specified by:
    `getSecondaryRow` in interface `RowManager`

### flushSecondaryRow

    public void flushSecondaryRow(Row row)

  Description copied from interface: `RowManager`
  Flush the secondary row; after flushing the row is available for reuse. It will retain all previously set values.

  Specified by:
    `flushSecondaryRow` in interface `RowManager`

### getAllRows

    public Row getAllRows(Table table,
                          int action)

  Description copied from interface: `RowManager`
  Return a logical row representing an update that should be made to all rows of the given table. The action must be one of `Row.ACTION_UPDATE`, `Row.ACTION_DELETE`.

  Specified by:
    `getAllRows` in interface `RowManager`

### flushAllRows

    public void flushAllRows(Row row)

  Description copied from interface: `RowManager`
  Flush the logical row.

  Specified by:
    `flushAllRows` in interface `RowManager`

### setObject

    public void setObject(Column col,
                          Object val)
                   throws SQLException

  Description copied from interface: `Row`
  Set the value of the given column in this row.

  Specified by:
    `setObject` in interface `Row`
  Overrides:
    `setObject` in class `RowImpl`
  Parameters:
    `col` - the column being set
    `val` - the value for the column
  Throws:
    `SQLException`
