Class JsonSpectrumWriter

  • All Implemented Interfaces:
    adams.core.AdditionalInformationHandler, adams.core.CleanUpHandler, adams.core.Destroyable, adams.core.GlobalInfoSupporter, adams.core.io.FileFormatHandler, adams.core.io.PrettyPrintingSupporter, adams.core.logging.LoggingLevelHandler, adams.core.logging.LoggingSupporter, adams.core.option.OptionHandler, adams.core.ShallowCopySupporter<adams.data.io.output.AbstractDataContainerWriter>, adams.core.SizeOfHandler, Serializable, Comparable
    public class JsonSpectrumWriter
extends AbstractSpectrumWriter
implements adams.core.io.PrettyPrintingSupporter
    Writes spectra in JSON format.
    Output format for single spectrum:
    - outputting the complete report:
    {
    "id": "someid",
    "format": "NIR",
    "waves": [1.0, 2.0],
    "amplitudes": [1.1, 2.1],
    "report": {
    "Sample ID": "someid",
    "GLV2": 1.123,
    "valid": true
    }
    }

    - outputting specific reference and meta-data values:
    {
    "id": "someid",
    "format": "NIR",
    "waves": [1.0, 2.0],
    "amplitudes": [1.1, 2.1],
    "reference": {
    "GLV2": 1.123
    },
    "meta-data": {
    "valid": true
    }
    }

    Multiple spectra get wrapped in an array called 'spectra'. 

    -logging-level <OFF|SEVERE|WARNING|INFO|CONFIG|FINE|FINER|FINEST> (property: loggingLevel)
    The logging level for outputting errors and debugging output.
    default: WARNING
 
    -output <adams.core.io.PlaceholderFile> (property: output)
    The file to write the container to.
    default: ${TMP}/out.tmp
 
    -use-reference-and-metadata <boolean> (property: useReferenceAndMetaData)
    If enabled, the only the specified reference and meta-data report values
    are output (in separate sections).
    default: false
 
    -reference-value <adams.data.report.Field> [-reference-value ...] (property: referenceValues)
    The reference values to output.
    default:
 
    -metadata-value <adams.data.report.Field> [-metadata-value ...] (property: metaDataValues)
    The meta-data values to output.
    default:
 
    -pretty-printing <boolean> (property: prettyPrinting)
    If enabled, the output is printed in a 'pretty' format.
    default: false
