Benedikt Ritter commented on LANG-1074:
---------------------------------------
Looks useful. I'm not sure I like the name however. Furthermore the element
parameter should be of type T.
> Add removeElementAll method in class ArrayUtils

> Key: LANG-1074
> URL: https://issues.apache.org/jira/browse/LANG-1074
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Affects Versions: 3.3.2
> Reporter: haiyang li
> Priority: Minor
> Fix For: Discussion
>
>
> Could we add the method: removeElementAll to remove all the occurrences of
> the specified element from the specified
> (boolean/char/byte/short/int/long/float/double/Object) array:
> {code:title=org.apache.commons.lang3.ArrayUtils.java|borderStyle=solid}
> public static <T> T[] removeElementAll(final T[] array, final Object
> element) {
> int index = indexOf(array, element);
> if (index == INDEX_NOT_FOUND) {
> return clone(array);
> }
> int[] indices = new int[array.length];
> int count = 0;
> indices[count++] = index;
> for (;;) {
> index = indexOf(array, element, ++index);
> if (index == INDEX_NOT_FOUND) {
> break;
> } else {
> indices[count++] = index;
> }
> }
> return (T[]) removeAll((Object) array, Arrays.copyOfRange(indices, 0,
> count));
> }
> {code}
> or maybe better:
> {code:title=org.apache.commons.lang3.ArrayUtils.java|borderStyle=solid}
> public static <T> T[] removeElement(final T[] array, final Object
> element, boolean removeAll) {
>
> if(!removeAll) {
> return removeElement(array, element)
> }
> int index = indexOf(array, element);
> if (index == INDEX_NOT_FOUND) {
> return clone(array);
> }
> int[] indices = new int[array.length];
> int count = 0;
> indices[count++] = index;
> for (;;) {
> index = indexOf(array, element, ++index);
> if (index == INDEX_NOT_FOUND) {
> break;
> } else {
> indices[count++] = index;
> }
> }
> return (T[]) removeAll((Object) array, Arrays.copyOfRange(indices, 0,
> count));
> }
> {code}
