.Methods in org.apache.lucene.util with type parameters of type Attribute Modifier and Type Method Description <T extends Attribute>
TAttributeSource. addAttribute(Class<T> attClass)
The caller must pass in a Class<? extends Attribute> value.<T extends Attribute>
TAttributeSource. getAttribute(Class<T> attClass)
Returns the instance of the passed in Attribute contained in this AttributeSourceMethods in org.apache.lucene.util that return types with arguments of type Attribute Modifier and Type Method Description Iterator<Class<? extends Attribute>>
AttributeSource. getAttributeClassesIterator()
Returns a new iterator that iterates the attribute classes in the same order they were added in.Method parameters in org.apache.lucene.util with type arguments of type Attribute Modifier and Type Method Description abstract AttributeImpl

Returns anAttributeImpl
for the suppliedAttribute
interface class.AttributeImpl

/AttributeSource
passing the class name of theAttribute
, a key and the actual value.
