## Class AbstractColumnGroup

- java.lang.Object
- - javax.faces.component.UIComponent
  - - javax.faces.component.UIComponentBase
    - - javax.faces.component.UIPanel
      - - org.richfaces.component.AbstractColumnGroup

- All Implemented Interfaces:
    EventListener, javax.faces.component.PartialStateHolder, javax.faces.component.StateHolder, javax.faces.component.TransientStateHolder, javax.faces.event.ComponentSystemEventListener, javax.faces.event.FacesListener, javax.faces.event.SystemEventListenerHolder, RowColumnStyleProps, Column, Row
  Direct Known Subclasses:
    UIColumnGroup

      public abstract class AbstractColumnGroup
      extends javax.faces.component.UIPanel
      implements Row, Column, RowColumnStyleProps

  The <rich:columnGroup> component combines multiple columns in a single row to organize complex parts of a table. The resulting effect is similar to using the breakRowBefore attribute of the <rich:column> component, but is clearer and easier to follow in the source code.

    - #### columns

          public Iterator<javax.faces.component.UIComponent> columns()

      Description copied from interface: `Row`
      Get iterator for all columns contained in this row.
      Specified by:
        `columns` in interface `Row`

    - #### setBreakBefore

          public void setBreakBefore(boolean newBreakBefore)

    - #### setRowKey

          public void setRowKey(javax.faces.context.FacesContext context,
                                Object rowKey)

      Specified by:
        `setRowKey` in interface `Row`

    - #### walk

          public void walk(javax.faces.context.FacesContext context,
                           DataVisitor visitor,
                           Object argument)

      Specified by:
        `walk` in interface `Row`

    - #### getColumnClasses

          public String getColumnClasses()

      Description copied from interface: `RowColumnStyleProps`
      Assigns one or more space-separated CSS class names to the columns of the table. If the CSS class names are comma-separated, each class will be assigned to a particular column in the order they follow in the attribute. If you have less class names than columns, the class will be applied to every n-fold column where n is the order in which the class is listed in the attribute. If there are more class names than columns, the overflow ones are ignored.
      Specified by:
        `getColumnClasses` in interface `RowColumnStyleProps`

    - #### getRowClasses

          public String getRowClasses()

      Description copied from interface: `RowColumnStyleProps`
      Assigns one or more space-separated CSS class names to the rows of the table. If the CSS class names are comma-separated, each class will be assigned to a particular row in the order they follow in the attribute. If you have less class names than rows, the class will be applied to every n-fold row where n is the order in which the class is listed in the attribute. If there are more class names than rows, the overflow ones are ignored.
      Specified by:
        `getRowClasses` in interface `RowColumnStyleProps`

    - #### getParentTable

          public RowColumnStyleProps getParentTable()
