Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
getDescription in interface ILegendClass
Returns:
The label
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

setDescription

public void setDescription(String label)
                    throws IOException,

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
setDescription in interface ILegendClass
Parameters:
label - The label (in)
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

getFormat

public ILegendClassFormat getFormat()
                             throws IOException,
                                    AutomationException
Optional. If non-null, then layer specifies class formatting information.

Remarks

A layer or renderer can provide legend class formatting information via this property, which makes it possible to store legend formatting information with layers in metadata-like fashion. However this is not normally done. Rather, legend formatting information usually comes from the legend. ILegendItem.LegendClassFormat is used and some patch settings can come from ILegend.LegendFormat .

So, when a legend is created, the code follows this logic:

  1. Check if ILegendClass.Format exists for the layer. If not, use ILegendItem.LegendClassFormat.
  2. For the patch settings, if a setting in ILegendItem.LegendClassFormat is null, then use the default value in ILegend.LegendFormat.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Supported Platforms

Windows, Solaris, Linux

Specified by:
getFormat in interface ILegendClass
Returns:
A reference to a com.esri.arcgis.carto.ILegendClassFormat
Throws:
IOException - If there are interop problems.
AutomationException - If the ArcObject component throws an exception.

setFormat

public void setFormat(ILegendClassFormat format)
               throws IOException,
                      AutomationException
Optional. If non-null, then layer specifies class formatting information.

Description

The layer can provide legend class formatting information via ILegendClass.Format. This makes it possible to store legend formatting information with layers in metadata-like fashion. However, layers normally do not provide a LegendClassFormat object. Rather, legend formatting information usually comes from the legend. ILegendItem.LegendClassFormat is used and some patch settings can come from ILegend.LegendFormat .

So, when a legend is created, the code follows this logic:

  1. Check if ILegendClass.Format exists for the layer. If not, use ILegendItem.LegendClassFormat.
  2. For the patch settings, if a setting in ILegendItem.LegendClassFormat is null, then use the default value in ILegend.LegendFormat.
