Thiruvalluvan M. G. updated AVRO-2260:
--------------------------------------
Component/s: java
> IDL Json Parsing is lossy, and it could be made more accurate.
> --------------------------------------------------------------
>
> Key: AVRO-2260
> URL: https://issues.apache.org/jira/browse/AVRO-2260
> Project: Apache Avro
> Issue Type: Bug
> Components: java
> Reporter: Zoltan Farkas
> Priority: Minor
>
> Currently all integers are handled as Long, and all floating point as Double,
> having basically the following issues:
> 1) cannot handle numbers larger that MAXLONG.
> 2) introducing unnecessary precision
> {code}
> JsonNode Json() :
> { String s; Token t; JsonNode n; }
> {
> ( s = JsonString() { n = new TextNode(s); }
> | (t=<INTEGER_LITERAL> { n = new LongNode(Long.parseLong(t.image)); })
> | (t=<FLOATING_POINT_LITERAL> {n=new
> DoubleNode(Double.parseDouble(t.image));})
> | n=JsonObject()
> | n=JsonArray()
> | ( "true" { n = BooleanNode.TRUE; } )
> | ( "false" { n = BooleanNode.FALSE; } )
> | ( "null" { n = NullNode.instance; } )
> )
> { return n; }
> }
> {code}
> This should be improved to:
> {code}
> JsonNode Json() :
> { String s; Token t; JsonNode n; }
> {
> ( s = JsonString() { n = new TextNode(s); }
> | (t=<INTEGER_LITERAL> {
> try {
> n = new IntNode(Integer.parseInt(t.image));
> } catch(NumberFormatException e) {
> try {
> n = new LongNode(Long.parseLong(t.image));
> } catch(NumberFormatException ex2) {
> n = new BigIntegerNode(new java.math.BigInteger(t.image));
> }
> }
> })
> | (t=<FLOATING_POINT_LITERAL> {n=new DecimalNode(new
> java.math.BigDecimal(t.image));})
> | n=JsonObject()
> | n=JsonArray()
> | ( "true" { n = BooleanNode.TRUE; } )
> | ( "false" { n = BooleanNode.FALSE; } )
> | ( "null" { n = NullNode.instance; } )
> )
> { return n; }
> }
> {code}
