[Simple-support] Serialization of nested lists, arrays

[Bernhard G. <ber...@tu...>]

Hello everybody,

I have a problem with serializing lists containing arrays, and I hope
that one of you can help me.

I have the following code:

  @ElementList(entry="reading")
  private List<BigDecimal[]> readings;

This is serialized as

  <readings>
    <reading length="2">42.5, 23.9</reading>
    <reading length="2">5.7, 8.3</reading>
  </readings>

But what I want is something like this (I don’t actually need the
length attribute):

  <readings>
    <reading length="2">
      <value>42.5</value>
      <value>23.9</value>
    </reading>
    <reading length="2">
      <value>5.7</value>
      <value>8.3</value>
    </reading>
  </readings>

I know that I can annotate a single array to get the inner
representation I want.

  @ElementArray(entry = "value")
  private BigDecimal[] reading;

  <reading length="2">
    <value>42.5</value>
    <value>23.9</value>
  </reading>

What I can’t figure out is how to combine these list and array
annotations or otherwise get the desired result.

I’d appreciate any advice.

Best regards,
Bernhard
