getExactTypeIfKnown

public AbstractType<?> getExactTypeIfKnown(java.lang.String keyspace)

Description copied from interface: Selectable

The type of the Selectable if it can be infered.

Specified by:

getExactTypeIfKnown in interface Selectable

Parameters:

keyspace - the keyspace on which the statement for which this is a Selectable is on.

Returns:

the type of this Selectable if inferrable, or null otherwise (for instance, the type isn't inferable for a bind marker. Even for literals, the exact type is not inferrable since they are valid for many different types and so this will return null too).
