----------------------------------
Summary: Create Iterable APIs
Key: LANG-927
URL: https://issues.apache.org/jira/browse/LANG-927
Project: Commons Lang
Issue Type: Improvement
Components: lang.*
Reporter: Henri Yandell
Fix For: Discussion
LANG-848 suggests having Iterable APIs in addition to CharSequence... (or
potentially other vararg methods).
Currently we have 10 Iterable APIs:
ClassUtils.hierarchy(final Class<?> type) {
ClassUtils.hierarchy(final Class<?> type, Interfaces interfacesBehavior) {
EnumUtils.generateBitVector(final Class<E> enumClass, final Iterable<E> values)
{
EnumUtils.generateBitVectors(final Class<E> enumClass, final Iterable<E>
values) {
StringUtils.join(final Iterable<?> iterable, final char separator) {
StringUtils.join(final Iterable<?> iterable, final String separator) {
StrBuilder.java.StrBuilder appendAll(final Iterable<?> iterable) {
StrBuilder.appendWithSeparators(final Iterable<?> iterable, String separator) {
Validate.noNullElements(final T iterable, final String message, final Object...
values) {
Validate.noNullElements(final T iterable) {
There are many other methods that could have such, but continuing to add
Iterable wherever we see varargs is going to bloat the API.
Perhaps adding a method to ArrayUtils (or IteratorUtils) can suffice:
public static E[] iteratorToArray(Iterator<E> iterator);
