Class DecisionTreeReader

Method Details

• getExpressionContext

  public RecordExpressionContext getExpressionContext()

• getDecisionTree

  public DecisionTree getDecisionTree()

• isOverwrite

  public boolean isOverwrite()

  Indicates if outcome fields replace existing non-null fields with the same name instead of being added under a numbered name (default false).

• setOverwrite

  public DecisionTreeReader setOverwrite(boolean overwrite)

  Indicates if outcome fields replace existing non-null fields with the same name instead of being added under a numbered name (default false).

• interceptRecord

  protected Record interceptRecord(Record record) throws Throwable

  Description copied from class: ProxyReader

  Overridden by subclasses to transform, drop, or observe a record on its way through this proxy.

  Contract for subclasses (see also docs/authoring/ProxyReader.md):

  • Return the record (possibly modified) to pass it downstream.
  • Return null to drop the record; the framework reads the next one.
  • Throw to fail the pipeline; the framework wraps the throwable in a DataException with .setRecord(record).
  • The nested DataReader is opened and closed for you; do not read from it here.
  • Do not call DataEndpoint.incrementRecordCount() here.

  Overrides:

  interceptRecord in class ProxyReader

  Throws:

  Throwable

• addExceptionProperties

  public DataException addExceptionProperties(DataException exception)

  Description copied from class: Endpoint

  Adds this endpoint's current state to a DataException. Since this method is called whenever an exception is thrown, subclasses should override it to add their specific information.

  Overrides:

  addExceptionProperties in class ProxyReader
