newSelectorFactory

public Selector.Factory newSelectorFactory(TableMetadata table,
 AbstractType<?> expectedType,
 List<ColumnMetadata> defs,
 VariableSpecifications boundNames)

Specified by:

newSelectorFactory in interface Selectable

getExactTypeIfKnown

public AbstractType<?> getExactTypeIfKnown(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).

selectColumns

public boolean selectColumns(Predicate<ColumnMetadata> predicate)

Description copied from interface: Selectable

Checks if this Selectable select columns matching the specified predicate.

Specified by:

selectColumns in interface Selectable

Returns:

true if this Selectable select columns matching the specified predicate, false otherwise.
