Example 1 with GetFieldMappingsResponse

use of org.elasticsearch.client.indices.GetFieldMappingsResponse in project ARLAS-server by gisaia.

the class ElasticTool method isDateField.

public static boolean isDateField(String field, ElasticClient client, String index) throws ArlasException {
    GetFieldMappingsResponse response = client.getFieldMapping(index, field);
    String lastKey = field.substring(field.lastIndexOf(".") + 1);
    return response.mappings().keySet().stream().anyMatch(indexName -> {
        GetFieldMappingsResponse.FieldMappingMetadata data = response.fieldMappings(indexName, field);
        boolean isFieldMetadaAMap = (data != null && data.sourceAsMap().get(lastKey) instanceof Map);
        if (isFieldMetadaAMap) {
            return Optional.of(((Map) data.sourceAsMap().get(lastKey))).map(m -> m.get(ES_TYPE)).map(Object::toString).filter(t -> t.equals(ES_DATE_TYPE)).isPresent();
        } else {
            // TODO : check if there is another way to fetch field type in this case
            return false;
        }
    });
