Method Detail

getElementTypes

public abstract List<Class> getElementTypes()

Collection/Array/Map content type.

When Enumerable is generic Type with actual Class arguments, returns this arguments. For example, if baseJavaType = Set<String>, returns List with String.class

For no generic types like Set, or generic types with unbounded type parameter like Set<V>, Set<?> returns empty List.

For array, returns List with Class.getComponentType()

isFullyParametrized

public abstract boolean isFullyParametrized()

returns true if Enumerable is generic Type and all its arguments are actual Classes

map

public abstract Object map(Object sourceEnumerable,
         EnumerableFunction mapFunction,
         OwnerContext owner)

Returns new instance of Enumerable with items from sourceEnumerable mapped by mapFunction.

isEmpty

public abstract boolean isEmpty(Object container)
