java.lang.Object
com.pervasive.datarush.tokens.record.MutableComposite
All Implemented Interfaces:
RecordSettable, TokenSettable, RecordTyped, TokenTyped
public class MutableComposite extends Object implements RecordSettable
A composite of settable scalar fields. A MutableComposite can be viewed as the loosest possible implementation of RecordSettable.

  • Constructor Details

    • MutableComposite

      public MutableComposite(T... fields)
      Construct a composite with the described schema using the supplied Named and ScalarSettable objects. The record type will be inferred from the provided fields.
      Parameters:
      fields - the named ScalarSettable objects to contain field values

    • MutableComposite

      public MutableComposite(RecordTokenType type, ScalarSettable[] fields)
      Construct a composite with the described schema using the supplied ScalarSettable objects. The field types in the schema will be cross-validated against the given objects.
      Parameters:
      type - the record schema to use for the resulting composite
      fields - the ScalarSettable objects to contain field values
      Throws:
      DRException - if the provided field types disagree with the types of the field objects
