----------------------------
Hello [~ggregory] [~novozhilov.a.russia]
Recursive formatting is controlled by the protected accept(Class<?>)
method.(defined in RecursiveToStringStyle class)
Although the default implementation always returns true, this is a deliberate
design choice. Subclasses are expected to override accept to exclude specific
classes from recursion.
The recursion decision is enforced in appendDetail(Object value) via the
accept(value.getClass()) check.
> MultilineRecursiveToStringStyle produces wrong output for BigDecimal

> Key: LANG-1452
> URL: https://issues.apache.org/jira/browse/LANG-1452
> Project: Commons Lang
> Issue Type: Bug
> Components: lang.builder.*
> Affects Versions: 3.7
> Reporter: Aleksey Novozhilov
> Priority: Major
> Labels: MultilineRecursiveToStringStyle
>
> Class has 2 BigDecimal fields:
> {code:java}
> BigDecimal biddecimal123 = new BigDecimal("123");
> BigDecimal biddecimal456 = new BigDecimal("456");
> {code}
> MultilineRecursiveToStringStyle produces this output:
> {quote}BDToString@36baf30c[
> biddecimal123=java.math.BigDecimal@7adf9f5f[
> intVal=<null>,
> scale=0
> ],
> biddecimal456=java.math.BigDecimal@63961c42[
> intVal=<null>,
> scale=0
> ]
> ]
> {quote}

> ToStringStyle.MULTI_LINE_STYLE doesn't have this problem. It was introduced
> with method
> {code:java}
> @Override
> public void appendDetail(final StringBuffer buffer, final String fieldName,
> final Object value){code}
> of MultilineRecursiveToStringStyle. It doesnt'n treat BigDecimal as a
> primitive type. So I had to do the following to solve my issue:
>
> {code:java}
> class FixedMultilineRecursiveToStringStyle extends
> MultilineRecursiveToStringStyle{
> @Override
> public void appendDetail(StringBuffer buffer, String fieldName, Object
> value) {
> if (!BigDecimal.class.equals(value.getClass())){
> super.appendDetail(buffer, fieldName, value);
> } else {
> buffer.append(value);
> }
> }
> }
> {code}
>
