Value Members

  1. package descriptor

    These classes serve as meta-data controlling JSON import by fromJson and export by toJson.

    These classes serve as meta-data controlling JSON import by fromJson and export by toJson. Among all, the meta-data contain identifiers based on which JSON edges will be matched to edge classes and Graph-specific serializers to be involved.

  2. package error

    Error/warning constants and message producing.

  3. package exp

    Export of graphs to JSON text.

  4. package imp

    Import of JSON text into graphs including the steps

    Import of JSON text into graphs including the steps

    1. parsing (extracting and checking all data from JSON texts relevant to Graph) and
    2. InputStream creation on the basis of parsing results in preparation of calling Graph.fromStream.

  5. def replacePlaceholders(source: String, params: Iterable[String], maxLength: Int = 50, paramPlaceholder: String = "{}"): String

    Replaces all occurrences of paramPlaceholder in source with the elements in params one by one.

    Replaces all occurrences of paramPlaceholder in source with the elements in params one by one. The result is guaranteed not to become longer than maxLength.

  6. package serializer

    Lift-JSON Serializers converting from/to unnamed JSON values and edge data containers (parameters) covering all predefined edge types.

    Lift-JSON Serializers converting from/to unnamed JSON values and edge data containers (parameters) covering all predefined edge types. They allow to save space as default Lift-JSON serializers would require the JSON text to contain JFields for every node and edge.
