Constructor Summary

BLCCollectionUtils()

Method Summary

static <T> Collection<T>	collect(Collection inputCollection, TypedTransformer<T> transformer) Delegates to CollectionUtils.collect(Collection, Transformer), but performs the necessary type coercion to allow the returned collection to be correctly casted based on the TypedTransformer.
static <T> T[]	collectArray(Collection inputCollection, TypedTransformer<T> transformer, Class<T> clazz) The same as collect(Collection, TypedTransformer) but returns an array
static <T> List<T>	collectList(Collection inputCollection, TypedTransformer<T> transformer) The same as collect(Collection, TypedTransformer) but returns an ArrayList
static <T> List<T>	selectList(Collection<T> inputCollection, TypedPredicate<T> predicate) Delegates to CollectionUtils.select(Collection, org.apache.commons.collections.Predicate), but will force the return type to be a List.
