  • Method Details

    • put

      void put(Serializable key, Serializable value)
      Associates the specified value with the specified key in the cache. if the cache previously contained a mapping for the specified key, the old value gets replaced
      Parameters:
      key - a key to associate the specified value
      value - the value to persist in the cache

    • putAll

      void putAll(Map<? extends Serializable,? extends Serializable> values)
      Copies all of the entries from the specified map to the cache.
      Parameters:
      values - values to be stored in the cache

    • get

      <T extends Serializable> Optional<T> get(Serializable key)
      Parameters:
      key - the key whose associated value is to be returned
      Returns:
      the value to which the specified key is mapped, or Option.empty() if this map contains no value for the specified key.

    • computeIfAbsent

      <T extends Serializable> T computeIfAbsent(Serializable key, MetadataCache.MetadataCacheValueResolver mappingFunction) throws org.mule.runtime.api.metadata.MetadataResolvingException, org.mule.runtime.api.connection.ConnectionException
      If the specified key is not already associated with a value, attempts to compute its value using the given mapping function and enters it into this map unless null.
      Parameters:
      key - the key whose associated value is to be returned
      Returns:
      the current (existing or computed) value associated with the specified key, or null if the computed value is null
      Throws:
      org.mule.runtime.api.metadata.MetadataResolvingException
      org.mule.runtime.api.connection.ConnectionException
