  • Method Details

    • getRelationalDataType

      public org.apache.calcite.rel.type.RelDataType getRelationalDataType(org.apache.calcite.adapter.java.JavaTypeFactory typeFactory)
      Description copied from interface: ColumnType
      Converts the column into the RelDataType that Calcite requires
      Specified by:
      getRelationalDataType in interface ColumnType
      Parameters:
      typeFactory - the type factory to use for creating the RelDataType
      Returns:
      the appropriate RelDataType for Calcite

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

    • scalarType

      public Class<?> scalarType()
      Returns the value of the scalarType record component.
      Returns:
      the value of the scalarType record component
