  • Method Details

    • genFromText

      public void genFromText(ContextMethodBuilder mb)
      Generate code to convert String representation. The code generated by this method assumes that the String value has already been pushed on the stack. It consumes this and leaves the converted value on the stack.
      Specified by:
      genFromText in class StringConversion
      Parameters:
      mb - method builder
    • pushDefault

      protected void pushDefault(ContextMethodBuilder mb)
      Push default value on stack. Just adds the appropriate instruction to the list for the method.
      Parameters:
      mb - method builder
    • genParseOptional

      public void genParseOptional(boolean attr, ContextMethodBuilder mb) throws JiBXException
      Generate code to parse and convert optional attribute or element. The code generated by this method assumes that the unmarshalling context and name information for the attribute or element have already been pushed on the stack. It consumes these and leaves the converted value (or default value, if the item itself is missing) on the stack.
      Specified by:
      genParseOptional in class StringConversion
      Parameters:
      attr - item is an attribute (vs element) flag
      mb - method builder
      Throws:
      JiBXException - if error in configuration
    • genParseRequired

      public void genParseRequired(boolean attr, ContextMethodBuilder mb) throws JiBXException
      Generate code to parse and convert required attribute or element. The code generated by this method assumes that the unmarshalling context and name information for the attribute or element have already been pushed on the stack. It consumes these and leaves the converted value on the stack.
      Specified by:
      genParseRequired in class StringConversion
      Parameters:
      attr - item is an attribute (vs element) flag
      mb - method builder
      Throws:
      JiBXException - if error in configuration
    • genToOptionalText

      protected BranchWrapper genToOptionalText(String type, ContextMethodBuilder mb, int extra) throws JiBXException
      Generate code to check if an optional value is not equal to the default. The code generated by this method assumes that the actual value to be converted has already been pushed on the stack. It consumes this, leaving the converted text reference on the stack if it's not equal to the default value.
      Specified by:
      genToOptionalText in class StringConversion
      Parameters:
      type - fully qualified class name for value on stack
      mb - method builder
      extra - count of extra values to be popped from stack if missing
      Returns:
      handle for branch taken when value is equal to the default (target must be set by caller)
      Throws:
      JiBXException - if error in configuration
    • convertDefault

      protected Object convertDefault(String text) throws JiBXException
      Convert text representation into default value object. This override of the base class method uses reflection to call the actual deserialization method, returning the wrapped result value. If a custom deserializer is defined this just returns the String value directly.
      Specified by:
      convertDefault in class StringConversion
      Parameters:
      text - value representation to be converted
      Returns:
      converted default value object
      Throws:
      JiBXException - on conversion error
    • isPrimitive

      public boolean isPrimitive()
      Check if the type handled by this conversion is of a primitive type.
      Specified by:
      isPrimitive in class StringConversion
      Returns:
      true to indicate primitive type
    • setSerializer

      protected void setSerializer(String ser) throws JiBXException
      Set serializer for conversion. This override of the base class method sets a flag to indicate that values must be converted to text before they are written to a document after executing the base class processing.
      Parameters:
      ser - fully qualified class and method name of serializer
      Throws:
      JiBXException - if serializer not found or not usable
    • setWhitespaceConverter

      protected void setWhitespaceConverter(String wsconv) throws JiBXException
      Set whitespace converter for conversion. This override of the base class method sets a flag to indicate that values must be read from a document as text and converted as a separate step after executing the base class processing.
      Overrides:
      setWhitespaceConverter in class StringConversion
      Parameters:
      wsconv - fully qualified class and method name of whitespace converter
      Throws:
      JiBXException - if whitespace converter not found or not usable
    • setDeserializer

      protected void setDeserializer(String deser) throws JiBXException
      Set deserializer for conversion. This override of the base class method sets a flag to indicate that values must be read from a document as text and converted as a separate step after executing the base class processing.
      Overrides:
      setDeserializer in class StringConversion
      Parameters:
      deser - fully qualified class and method name of deserializer
      Throws:
      JiBXException - if deserializer not found or not usable
    • derive

      public StringConversion derive(String type, String ser, String conv, String dser, String dflt) throws JiBXException
      Derive from existing formatting information. This allows constructing a new instance from an existing format of the same or an ancestor type, with the properties of the existing format copied to the new instance except where overridden by the supplied values.
      Specified by:
      derive in class StringConversion
      Parameters:
      type - fully qualified name of class handled by conversion (null if inherited)
      ser - fully qualified name of serialization method (null if inherited)
      conv - fully qualified name of whitespace conversion method (null if inherited)
      dser - fully qualified name of deserialization method (null if inherited)
      dflt - default value text (null if inherited)
      Returns:
      new instance initialized from existing one
      Throws:
      JiBXException - if error in configuration information
