Class RoundingUtils.SignificantDigitsSerializer

java.lang.Object
com.fasterxml.jackson.databind.JsonSerializer<Double>
ubic.gemma.core.util.RoundingUtils.SignificantDigitsSerializer
All Implemented Interfaces:
com.fasterxml.jackson.databind.jsonFormatVisitors.JsonFormatVisitable
Enclosing class:
RoundingUtils
public static class RoundingUtils.SignificantDigitsSerializer extends com.fasterxml.jackson.databind.JsonSerializer<Double>
Applies RoundingUtils.round(double) at serialization time, leaving the in-memory value exact.

Use this rather than rounding in a value object's constructor wherever the field is also read by application code — the differential-expression endpoints rank rows by corrected p-value, and rounding before the sort can reorder near-ties.

Opt in per field with @JsonSerialize(using = RoundingUtils.SignificantDigitsSerializer.class). It is deliberately not registered on the shared ObjectMapper: that would also round GEEQ scores and thresholds.
