Return the types for which this variable is a representation. For example in the following sparql declaration the "?myVar) variable is a representation of the "orig:Actor" type:

 ?myVar rdf:type orig:Actor
 

Returns:

the types

getFirstType

public PrefixedName getFirstType()

Return the first associated type for this variable. It will return null if isFromTypes() return false.

Returns:

the first associated type for this variable

hasType
