Package org.apache.tika.serialization.serdes

Class ParseContextDeserializer

java.lang.Object
com.fasterxml.jackson.databind.JsonDeserializer<ParseContext>
org.apache.tika.serialization.serdes.ParseContextDeserializer
All Implemented Interfaces:
com.fasterxml.jackson.databind.deser.NullValueProvider
public class ParseContextDeserializer extends com.fasterxml.jackson.databind.JsonDeserializer<ParseContext>
Deserializes ParseContext from JSON.

Handles two types of entries:

  • "typed" section: Deserialized directly to typed objects in the context map
  • Other entries: Stored as JSON configs for lazy resolution

Example input: 

 {
   "typed": {
     "handler-config": {"type": "XML", "parseMode": "RMETA"}
   },
   "metadata-filters": ["mock-upper-case-filter"]
 }

      public ParseContext deserialize(com.fasterxml.jackson.core.JsonParser jsonParser, com.fasterxml.jackson.databind.DeserializationContext ctxt) throws IOException

      Throws:
      IOException

    • readParseContext

      public static ParseContext readParseContext(com.fasterxml.jackson.databind.JsonNode jsonNode, com.fasterxml.jackson.databind.ObjectMapper mapper) throws IOException
      Deserializes a ParseContext from a JsonNode.

      The "typed" section is deserialized directly to typed objects in the context map. All other fields are stored as JSON config strings for lazy resolution.

      Duplicate detection is performed within a single document: if multiple entries resolve to the same context key (e.g., both "bouncy-castle-digester" and "commons-digester" resolve to DigesterFactory), an IOException is thrown.

      Parameters:
      jsonNode - the JSON node containing the ParseContext data
      mapper - the ObjectMapper for deserializing typed objects
      Returns:
      the deserialized ParseContext
      Throws:
      IOException - if deserialization fails or duplicate context keys are detected
