java.lang.Object
com.networknt.schema.CollectorContext
public class CollectorContext extends Object
Context for holding the output returned by the Collector implementations.

  • Constructor Details

    • CollectorContext

      public CollectorContext()
      Default constructor will use an unsynchronized HashMap to store data. This is suitable if the collector context is not shared with multiple threads.

    • CollectorContext

      public CollectorContext(Map<String,Object> collectorMap, Map<String,Object> collectorLoadMap)
      Constructor that creates the context using the specified instances to store data.

      If for instance the collector context needs to be shared with multiple threads a ConcurrentHashMap can be used.

      Parameters:
      collectorMap - the collector map
      collectorLoadMap - the collector load map

  • Method Details

    • add

      public <E> void add(String name, Collector<E> collector)
      Adds a collector with give name. Preserving this method for backward compatibility.
      Type Parameters:
      E - element
      Parameters:
      name - String
      collector - Collector

    • add

      public <E> void add(String name, Object object)
      Adds a collector or a simple object with give name.
      Type Parameters:
      E - element
      Parameters:
      name - String
      object - Object

    • get

      public Object get(String name)
      Gets the data associated with a given name. Please note if you are collecting Collector instances you should wait till the validation is complete to gather all data.

      When CollectorContext is used to collect Collector instances for a particular key, this method will return the Collector instance as long as loadCollectors() method is not called. Once the loadCollectors() method is called this method will return the actual data collected by collector.

      Parameters:
      name - String
      Returns:
      Object

    • getCollectorMap

      public Map<String,Object> getCollectorMap()
      Gets the collector map.
      Returns:
      the collector map

    • getAll

      public Map<String,Object> getAll()
      Returns all the collected data. Please look into get(String) method for more details.
      Returns:
      Map

    • combineWithCollector

      public void combineWithCollector(String name, Object data)
      Combines data with Collector identified by the given name.
      Parameters:
      name - String
      data - Object

    • loadCollectors

      public void loadCollectors()
      Loads data from all collectors.
