as

@Nullable
public <T> T as(Class<T> clazz)

Description copied from interface: SelectableColumn

Request an implementation of a particular interface. Physical nested columns, and virtual columns that act as a nested column, should implement:

• NestedColumnTypeInspector, required.
• NestedColumnSelectorFactory, required.
• NestedVectorColumnSelectorFactory, required.
• NestedColumnIndexSupplier, if the column has indexes.

Specified by:

as in interface SelectableColumn

Type Parameters:

T - desired interface

Parameters:

clazz - desired interface

Returns:

instance of clazz, or null if the interface is not supported by this segment
