                return new ByteSize(value, unit);
            }
        }
    }
    throw new IllegalArgumentException("Unknown unit '" + unitString + "'");
}

Example 3 with JsonCreator

use of com.fasterxml.jackson.annotation.JsonCreator in project druid by druid-io.

the class InlineDataSource method fromJson.

/**
 * Factory method for Jackson. Used for inline datasources that were originally encoded as JSON. Private because
 * non-Jackson callers should use {@link #fromIterable}.
 */
@JsonCreator
private static InlineDataSource fromJson(@JsonProperty("columnNames") List<String> columnNames, @JsonProperty("columnTypes") List<ColumnType> columnTypes, @JsonProperty("rows") List<Object[]> rows) {
    Preconditions.checkNotNull(columnNames, "'columnNames' must be nonnull");
    if (columnTypes != null && columnNames.size() != columnTypes.size()) {
        throw new IAE("columnNames and columnTypes must be the same length");
    }
    final RowSignature.Builder builder = RowSignature.builder();
    for (int i = 0; i < columnNames.size(); i++) {
        final String name = columnNames.get(i);
        final ColumnType type = columnTypes != null ? columnTypes.get(i) : null;
        builder.add(name, type);
    }
    return new InlineDataSource(rows, builder.build());
}
