    • Field

      public Field(org.apache.calcite.rel.type.RelDataType dataType)
      Overloaded constructor for creation of fields which carry only about dataType and don't represent named columns. Example of such usage is key and value types of Map columns.
      Parameters:
      dataType - field type

  • Method Details

    • getName

      public String getName()
      Gets the name of this field.

    • getType

      public org.apache.calcite.sql.type.SqlTypeName getType()
      Gets the data type of this field. (Data type only; not full datatype descriptor.)

    • getPrecision

      public Integer getPrecision()
      Gets the precision of the data type descriptor of this field. The precision is the precision for a numeric type, the length for a string type, or the start unit precision for an interval type.

    • getScale

      public Integer getScale()
      Gets the numeric scale of the data type descriptor of this field, for numeric types.

    • getIntervalQualifier

      public org.apache.calcite.sql.SqlIntervalQualifier getIntervalQualifier()
      Gets the interval type qualifier of the interval data type descriptor of this field (iff interval type).

    • getStartUnit

      public org.apache.calcite.avatica.util.TimeUnit getStartUnit()
      Gets the time range start unit of the type qualifier of the interval data type descriptor of this field (iff interval type).

    • getEndUnit

      public org.apache.calcite.avatica.util.TimeUnit getEndUnit()
      Gets the time range end unit of the type qualifier of the interval data type descriptor of this field (iff interval type).

    • getFractionalSecondPrecision

      public Integer getFractionalSecondPrecision()
      Gets the fractional second precision of the type qualifier of the interval data type descriptor of this field (iff interval type). Gets the interval type descriptor's fractional second precision (iff interval type).

    • getIsNullable

      public Boolean getIsNullable()

      public View.Field getKeyType()
      Gets key type for fields whose type is SqlTypeName.MAP
      Returns:
      key type of map

    • getValueType

      public View.Field getValueType()
      Gets value type for fields whose type is SqlTypeName.MAP
