/**
* Use this annotation to specify that a declared numeric Java field should map to a JSON string.
*
* By default declared Java numeric fields are stored as JSON numbers. For example:
*
*
*
* class A {
* @Key BigInteger value;
* }
*
*
*
* can be used for this JSON content:
*
*
*
* {"value" : 12345768901234576890123457689012345768901234576890}
*
*
*
* However, if instead the JSON content uses a JSON String to store the value, one needs to use
* the {@link JsonString} annotation. For example:
*
*
*
* class B {
* @Key @JsonString BigInteger value;
* }
*
*
*
* can be used for this JSON content:
*
*
*
* {"value" : "12345768901234576890123457689012345768901234576890"}
