public static class ColumnAccessors.DateColumnWriter extends AbstractFixedWidthWriter.BaseFixedWidthWriter

  • Constructor Details

    • DateColumnWriter

      public DateColumnWriter(ValueVector vector)

  • Method Details

    • vector

      public BaseDataValueVector vector()
      Specified by:
      vector in class AbstractScalarWriterImpl

    • width

      public int width()
      Specified by:
      width in class AbstractFixedWidthWriter

    • valueType

      public ValueType valueType()
      Description copied from interface: ScalarWriter
      Describe the type of the value. This is a compression of the value vector type: it describes which method will return the vector value.
      Returns:
      the value type which indicates which get method is valid for the column

    • extendedType

      public ValueType extendedType()
      Description copied from interface: ScalarWriter
      The extended type of the value, describes the secondary type for DATE, TIME and TIMESTAMP for which the value type is int or long.
      Specified by:
      extendedType in interface ScalarWriter
      Overrides:
      extendedType in class AbstractScalarWriter

    • setLong

      public final void setLong(long value)
      Specified by:
      setLong in interface ValueWriter
      Overrides:
      setLong in class BaseScalarWriter

    • writeLong

      public final void writeLong(DrillBuf buf, long value)

    • setDate

      public final void setDate(LocalDate value)
      Specified by:
      setDate in interface ValueWriter
      Overrides:
      setDate in class BaseScalarWriter

    • setValue

      public final void setValue(Object value)
      Description copied from interface: ValueWriter
      Write value to a vector as a Java object of the "native" type for the column. This form is available only on scalar writers. The object must be of the form for the primary write method above.

      Primarily to be used when the code already knows the object type.

      Parameters:
      value - a value that matches the primary setter above, or null to set the column to null
      See Also:

    • setDefaultValue

      public final void setDefaultValue(Object value)
      Description copied from interface: ScalarWriter
      Set the default value to be used to fill empties for this writer. Only valid for required writers: null writers set this is-set bit to 0 and set the data value to 0.
      Parameters:
      value - the value to set. Cannot be null. The type of the value must match that legal for ValueWriter.setValue(Object)

    • copy

      public final void copy(ColumnReader from)
      Description copied from interface: ColumnWriter
      Copy a single value from the given reader, which must be of the same type as this writer.
      Parameters:
      from - reader to provide the data
