[jira] [Closed] (LANG-872) EqualsBuilder methods append(Object[],Object[]) and append(Object,Object) treats array class dirrerently

Duncan Jones closed LANG-872.
-----------------------------
       Resolution: Not A Problem
         Assignee: Duncan Jones
    Fix Version/s:     (was: Discussion)

I've added an explanation to the Javadoc to explain how {{append(Object[],Object[])}} works. I think that's sufficient to resolve this issue.

Please re-open and comment if you disagree!.

Javadoc change to address LANG-872. 

Javadocs for append(Object[],Object[]) updated to indicate it only
compares the contents of the arrays, not the type of the arrays.

> Method {{EqualsBuilder.append(Object[],Object[])}} ignores classes of passed arrays and returns true if contents of both arrays are equal.
> Method {{EqualsBuilder.append(Object,Object)}} returns false immediately if types of passed array arguments are different.
> For example:
> {code}
>     public void testEqualsArrays() {
>         Object[] aArray = new Object[] {"Value"};
>         Object[] bArray = new String[] {"Value"};
>         boolean compareAsArrays = new EqualsBuilder().append(aArray, bArray).isEquals();
>         // compareAsArrays is true
>         Object aObj  = aArray;
>         Object bObj  = bArray;
>         boolean compareAsObjects = new EqualsBuilder().append(aObj, bObj).isEquals();
>         // compareAsObjects is false
>         assertTrue(compareAsArrays == compareAsObjects); //Fails
>     }
> {code}
> Results of both methods should be consistent.
