Sebb commented on LANG-1404:
----------------------------
LANG is for general purpose routines.
I think what you need is a domain-specific method.
It should check for 0, 1, null and return the appropriate bool.
Any other value should fail as it implies a coding bug.
This can then be documented with details of the convention that is being used,
and pointers to any existing documentation on the convention.
> BooleanUtils.toBoolean(Integer) method added
> --------------------------------------------

> Key: LANG-1404
> URL: https://issues.apache.org/jira/browse/LANG-1404
> Project: Commons Lang
> Issue Type: Improvement
> Components: lang.*
> Reporter: Ruslan Sibgatullin
> Priority: Minor
>
> Right now to convert an Integer to boolean there is either a null check
> needed:
> {{final Integer value = 1;}}
> {{if (value != null) {}}
> {{ if(BooleanUtils.toBoolean(value)) {}}
> {{ // some code}}
> }
> {{}}}
> or two methods call:
>
> {{final Integer value = 1;}}
> {{final Boolean b = BooleanUtils.toBooleanObject(value);}}
> {{if (BooleanUtils.toBoolean(b)) {}}
> {{ // some code}}
> {{}}}
> Some code-sugar is added with the help of method that accepts Integer and
> returns boolean:
> {{final Integer value = 1;}}
> {{if (BooleanUtils.toBoolean(value)) {}}
> // some code
> {{}}}
