/**
*
* PropertyColumnTableDescription is the default implementation of {@link TableDescription} which uses class
* introspection to create columns. Each column is based on a property of the class and thus should be
* accessible through an isXXX or getXXX method.
*
*
*
* Additionally writing capabilities are available by providing a specific {@link javax.swing.table.TableCellEditor}. When
* using this table description with a detail form and a backing formModel, take a look at the
* {@link ValueModelTableCellEditor}.
*
*
*
* Nested properties can be accessed using the dot notation: 'propertyA.propertyB'. At any point in this
* chaining getting a null value will stop evaluating the expression and returns null.
*
*
* Typical usage of a {@link PropertyColumnTableDescription}:
*
*
* PropertyColumnTableDescription tableDesc = new PropertyColumnTableDescription("id", MyType.class);
* tableDesc.addPropertyColumn("propertyA");
* tableDesc.addPropertyColumn("propertyB").addRenderer(MySpecificTableCellRenderer);
* tableDesc.addPropertyColumn("propertyC").addMinWidth(25).addMaxWidth(100);
*
*
*
* More possibilities and additional addXXX methods can be found in the {@link PropertyColumn} class.
*
*
* NOTE: this class provides a number of addPropertyColumn(...) methods to add columns. As there are many
* features on a column, this led to a huge number of these constructions. To simplify the
* {@link PropertyColumnTableDescription} class and the adding of new features, a new way of column creation
* has been implemented with the addXXX methods on the {@link PropertyColumn} class. New features will be
* exclusive to the addXXX methods.
*
