  • Method Details

    • read

      public abstract D read(byte[] serialized)
      Generates a descriptor from a byte array.

      Note that compatibility of the descriptor configuration used to create the serialized form and the one used to create this reader instance can not be checked. The binary form read by this method is compatible only with the binary form provided by the chemaxon.descriptors API implementation for the represented XML configuration. This binary form is not compatible with the DescriptorSerializer represented by the DescriptorGenerator returned by getDescriptorGenerator().

      Parameters:
      serialized - Serialize byte array representation
      Returns:
      a bare descriptor form

    • getXmlConfig

      public abstract String getXmlConfig()
      Gets configuration string.
      Returns:
      xml config

    • getDescriptorGenerator

      public abstract DescriptorGenerator<D> getDescriptorGenerator()
      Associated descriptor generator.

      Associated generator is compatible with the read descriptors created by method read(byte[]). Note that the DescriptorSerializer exposed by the returned generator is not compatible with the binary form represented by this reader.

      Returns:
      Associated generator

    • getStandardizerWrapper

      public abstract StandardizerWrapper getStandardizerWrapper()
      Get represented standardizer wrapper.

      Note that the represented standardizer configuration might not be recognized by an implementation. In these cases an IllegalStateException is thrown.

      Returns:
      Represented standardizer wrapper
      Throws:
      IllegalStateException - When represented standardizer configuration is not recognized

    • createNewReader

      public static MDTableReader<? extends Descriptor> createNewReader(String xmlConfig)
      Create an MDTableReader from the xml configuration string.
      Parameters:
      xmlConfig - xml config
      Returns:
      an MDTableReader implementation
      Throws:
      IllegalArgumentException - invalid xml string
