## Class CallerContext

- java.lang.Object
- - org.apache.synapse.commons.throttle.core.CallerContext

- All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable
  Direct Known Subclasses:
    DomainBaseCallerContext, IPBaseCallerContext, RoleBaseCallerContext

      public abstract class CallerContext
      extends java.lang.Object
      implements java.io.Serializable, java.lang.Cloneable

  Contains all runtime data for a particular remote caller. provides the default rate based access controller algorithm implementation. This is not thread-safe
