Package docking.widgets.table.constraint

Class ColumnTypeMapper<T,M>

java.lang.Object

docking.widgets.table.constraint.ColumnTypeMapper<T,M>

Type Parameters:

T - The column type that has no inherent ColumnConstraint for filtering that column type.

M - The column type to map to that already has ColumnConstraints defined for that type.

All Implemented Interfaces:

ExtensionPoint

Direct Known Subclasses:

AddressBasedLocationColumnTypeMapper, DataTypeColumnTypeMapper, DateColumnTypeMapper, FloatColumnTypeMapper, NamespaceColumnTypeMapper, ObjectToStringMapper, ProgramLocationColumnTypeMapper, ScalarToLongColumnTypeMapper, SymbolColumnTypeMapper

public abstract class ColumnTypeMapper<T,M>
extends java.lang.Object
implements ExtensionPoint

ColumnConstraintTypeMappers allows columns of one type be filterable using an existing ColumnConstraint for a different type by defining a mapping from the column type to the desired filter type. To get the benefit of one of these mappers, all that is required is to implement one of these mappers. The mapper class must be public and it's name must end in "TypeMapper".

For example, if you have a column type of "Person" that holds various information about a person including their age and you want to filter on their age, you could define a ColumnTypeMapper that converts a "Person" to an int. Just by creating such a mapper class, any table with "Person" column types would now be able to filter on a person's age.

In the example above, you created a filter of a single attribute of person. If, however, you want more than that, you could instead create a new ColumnConstraint that filters on more attributes of a Person. See NumberColumnConstraintProvider for an example of how to create these ColumnConstraints and their associated editors.
