  • Method Details

    • serializeNulls

      void serializeNulls(boolean serializeNulls)
      Set to serialise null values or not.

    • serializeNulls

      boolean serializeNulls()
      Return true if null values should be serialised.

    • serializeEmpty

      void serializeEmpty(boolean serializeEmpty)
      Set to serialise empty collections or not.

    • serializeEmpty

      boolean serializeEmpty()
      Return true if empty collections should be serialised.

    • pretty

      void pretty(boolean pretty)
      Set tp true to output json in pretty format.

    • path

      String path()
      Return the current path.

    • allNames

      void allNames(PropertyNames names)
      Set the property names that will be used for all json generation.

      These names should be used for all json generation for this generator and set once rather than set per object via names(PropertyNames).

      This is used by view json generation where all the names are known at the point when the view is created (a sort of flattened nested tree).

    • names

      void names(PropertyNames names)
      Set the current property names.

      This is expected to be called per object after each call to beginObject().

    • name

      void name(int position)
      Set the next property name to write by position. This uses the already encoded name values of PropertyNames.

    • name

      void name(String name)
      Set the next property name to write.

      This is generally less efficient than using names(PropertyNames) and name(int).

    • beginArray

      void beginArray()
      Write array begin.

    • endArray

      void endArray()
      Write array end.

    • emptyArray

      void emptyArray()
      Write empty array.

    • beginObject

      void beginObject()
      Write object begin.

    • endObject

      void endObject()
      Write object end.

    • nullValue

      void nullValue()
      Write null value.

    • value

      void value(String value)
      Write a string value.

    • value

      void value(boolean value)
      Write a boolean value.

    • value

      void value(int value)
      Write an int value.

    • value

      void value(long value)
      Write a long value.

    • value

      void value(double value)
      Write a double value.

    • value

      void value(Boolean value)
      Write a Boolean value.

    • value

      void value(Integer value)
      Write an Integer value.

    • value

      void value(Long value)
      Write a Long value.

    • value

      void value(Double value)
      Write a Double value.

    • value

      void value(BigDecimal value)
      Write a BigDecimal value.

    • value

      void value(BigInteger value)
      Write a BigInteger value.

    • jsonValue

      void jsonValue(Object value)
      Write a value that could be any value.

    • writeNewLine

      void writeNewLine()
      Write raw content. This is typically used to write new line characters for x-json-stream content.

    • flush

      void flush()
      Flush the writer.
      Specified by:
      flush in interface Flushable
