Hi, I am trying to build GeoTools and I get two errors in gt-metadata module.I
use Eclipse - Mars.1 Release (4.5.1) - in Windows.
...\modules\library\metadata\src\main\java\org\geotools\factory\CategoryRegistry.java
1) public CategoryRegistry(final FactoryRegistry factoryRegistry,
final Iterable<Class<?>> categories) { ... // use an unmodifiable
map to guarantee immutability this.categories = stream(categories)
.collect( collectingAndThen(
toMap(category -> category,
category -> new InstanceRegistry<>(factoryRegistry,category), <-- ERROR
(firstRegistry, secondRegistry) ->
secondRegistry),
Collections::unmodifiableMap)); }
ERROR --> Type mismatch: cannot convert from Object to
Map<Class<?>,CategoryRegistry.InstanceRegistry<?>>
2) public <S> Optional<S> getInstanceOfType(Class<S> type) { ...
return streamCategories().filter(category ->
category.isAssignableFrom(type)) .map(this::instanceRegistry)
<--
ERROR .flatMap(registry ->
stream(registry.getInstanceOfType(type))).findFirst(); }
ERROR -> Type mismatch: cannot convert from Stream<Object> to <unknown>
I can fix these errors with a pair of minor changes:
1) public CategoryRegistry(final FactoryRegistry factoryRegistry,
final Iterable<Class<?>> categories) { ... // use an unmodifiable
map to guarantee immutability
this.categories = stream(categories) .collect(
collectingAndThen( toMap(category
-> category, category -> new
InstanceRegistry<Class<?>>(factoryRegistry,category),
(firstRegistry, secondRegistry) -> secondRegistry),
Collections::unmodifiableMap)); }
2) public <S> Optional<S> getInstanceOfType(Class<S> type) { ...
return streamCategories().filter(category ->
category.isAssignableFrom(type)) .map(category ->
(InstanceRegistry<?>) instanceRegistry(category))
.flatMap(registry -> stream(registry.getInstanceOfType(type))).findFirst(); }
But I do not know if they are right. Could you help me? Am I missing anything?
Thanks in advanceAlvaro
