  • Method Details

    • getFixedSize

      public int getFixedSize()
      Description copied from interface: FixedWidthType

      public boolean isComparable()
      Description copied from interface: Type
      True if the type supports equalTo and hash.
      Specified by:
      isComparable in interface Type
      Overrides:
      isComparable in class AbstractType

    • isOrderable

      public boolean isOrderable()
      Description copied from interface: Type
      True if the type supports compareTo.
      Specified by:
      isOrderable in interface Type

    • getObjectValue

      public Object getObjectValue(ConnectorSession session, Block block, int position)
      Description copied from interface: Type
      Gets an object representation of the type value in the block position. This is the value returned to the user via the REST endpoint and therefore must be JSON serializable.

      appendTo in interface Type

    • getDouble

      public double getDouble(Block block, int position)
      Description copied from interface: Type
      Gets the value at the block position as a double.

      Overrides:
      getDouble in class AbstractType

    • writeDouble

      public void writeDouble(BlockBuilder blockBuilder, double value)
      Description copied from interface: Type
      Writes the double value into the BlockBuilder.
