state between messages. By default, object store
connector not present in Mule palette. So you can install
it from Anypoint exchange.
Object Store With Mule ESB Object store connector can performed various operations like Contains, Dual store, Remove, Retrieve,
Retrieve all keys, Retrieve and Store and Store.
Contains is used to verify if given key is present in object store.
Dual store stores a value using key and also stores a key using value.
Remove is to remove the respective key from object store.
Retrieve is used to retrieve an object from the object store and make it available in the specified property scope of a Mule Message.
Retrieve all keys will returns list of all keys present in object store.
Retrieve and Store is used to retrieve and store object in same operation.
Store is used to store the object in object store.
