in class DataValue.UtilityFactory
protected DataValueRendererFamily getRendererFamily(DataColumnSpec spec)
Views that rely on renderer implementations will get a list of all
available renderers by invoking
DataType.getRenderer(DataColumnSpec)
on the column's
DataType
which makes sure that all renderer implementations of compatible
values are returned.
getRendererFamily
in class DataValue.UtilityFactory
spec
- the DataColumnSpec
of the
column for which the renderers are
used. Most of the renderer implementations won't need
column domain information but some do. For instance a
class that renders the double value in the column
according to the min/max values in the column domain.
