## com.sas.graphics.components
Class TableAxisZone

    com.sas.graphics.components.TableAxisZone

    public class TableAxisZone

The TableAxisZone class stores zone attributes for a table axis. Zoning can be done based a Variable displayed in the TableAxis or by specifying a level in the tree of a Hierarchical TreeTable.

## Usage

An array of TableAxisColumn is used to set the columns of a TableAxis with the TableAxisModel.setColumns method. The Variables used in a visible column of this table can be used to zone by. In a hierarchical tree table version of the table, you can also specify a level in the tree to zone by. These zoning Variables and level's will be applied in the order they appear in the array order they occur in TableAxisModel.setZones() method.
You can access a TableAxisModel in the chart by calling the getTableAxisModel() on the GraphModel. From there you can specify the TableAxisZones you wish to see in the table and chart.
Ex.

     GanttChart ganttChart = new GanttChart();
     GanttChartModel ganttChartModel = ganttChart.getGraphModel();
     TableAxisModel tableAxisModel = ganttChartModel.getTableAxisModel();
     TableAxisColumn column[] = tableAxisModel.getColumns();

     TableAxisZone taz[] = new TableAxisZone[2];
     taz[0] = new TableAxisZone(column[0].getVariable());
     taz[1] = new TableAxisZone(2);  // level 2 of a hierarchical tree table
     tableAxisModel.setZones(taz);

## Behavior

All variables specified as a zone must also be specified as a visible TableAxisColumn. Variables specified as zones that are not also a visible TableAxisColumn will be ignored.

Constructor Summary
`TableAxisZone(int treeLevel)` Constructor designating the level in the tree to zone on.
`TableAxisZone(Variable var)` Constructor designating variable to create a zone on in the table and chart.

Method Summary
`void` | `apply(TableAxisZone theOtherObject)` Utility method to convey properties contained in "theOtherObject" to this object.
`boolean` | `equals(java.lang.Object obj)` Determines whether another object is equal to this `TableAxisColumn`.
`int` | `getTreeLevel()` Returns the Level used for this zone.
`Variable` | `getVariable()` Returns the Variable used for this zone.
`int` | `hashCode()` Computes the hash code for this `TableAxisZone`.

Constructor Detail

### TableAxisZone

    public TableAxisZone(Variable var)

  Constructor designating variable to create a zone on in the table and chart. The variable must be a variable also used in a TableAxisColumn and be visible in the in the table. Use TableAxisModel.setColumns() to specify columns in the table.

  Parameters:
    `var` - the Variable to be used for zoning
  Throws:
    `java.lang.IllegalArgumentException` - if null Variable is passed in.

### TableAxisZone

    public TableAxisZone(int treeLevel)

  Constructor designating the level in the tree to zone on.

  Parameters:
    `treeLevel` - Tree Level to zone table and chart on.
  Throws:
    `java.lang.IllegalArgumentException` - if level < 0.

Method Detail

### apply

    public void apply(TableAxisZone theOtherObject)

  Utility method to convey properties contained in "theOtherObject" to this object.

  Note: Contained "models" (i.e. properties that are subclasses of ModelBase) will in turn be called on to convey their properties to the like contained models in the other object. In that respect this can be considered a "tree" type copy.

  Also Note: This is a deep copy. Thus after the copy, mutable properties will not be shared by the two instances.

  Parameters:
    `theOtherObject` - properties applied to this instance

### equals

    public boolean equals(java.lang.Object obj)

  Determines whether another object is equal to this `TableAxisColumn`.

  The result is `true` if and only if the argument is not `null` and is a `TableAxisColumn` object that has the same property values as this object.

  Overrides:
    `equals` in class `ModelBase`
  Parameters:
    `obj` - the object to test for equality with this `TableAxisZone`
  Returns:
    `true` if the objects are the same; `false` otherwise.

### getVariable

    public Variable getVariable()

  Returns the Variable used for this zone.

  Returns:
    Variable for the table zone

### getTreeLevel

    public int getTreeLevel()

  Returns the Level used for this zone.

  Returns:
    Level in the tree for the table zone

### hashCode

    public int hashCode()

  Computes the hash code for this `TableAxisZone`.

  Overrides:
    `hashCode` in class `ModelBase`
  Returns:
    a hash code value for this object.
