      • getExpiryDelay

        public Seconds getExpiryDelay​(ParameterResolver resolver)
        Return the amount of time since the last update that entries are kept by the cache before being expired. Entries that have expired are not accessible and are evicted the next time a client accesses the cache. Any attempt to read an expired entry results in a reloading of the entry from the CacheStore.
        Parameters:
        resolver - the ParameterResolver
        Returns:
        the expiry delay

      • setExpiryDelay

        @Injectable
public void setExpiryDelay​(Expression<Seconds> expr)
        Set the expiry delay.
        Parameters:
        expr - the expiry delay expression

      • getHighUnits

        public Units getHighUnits​(ParameterResolver resolver)
        Return the limit of cache size. Contains the maximum number of units that can be placed n the cache before pruning occurs. An entry is the unit of measurement, unless it is overridden by an alternate unit-calculator. When this limit is exceeded, the cache begins the pruning process, evicting entries according to the eviction policy. Legal values are positive integers or zero. Zero implies no limit.
        Parameters:
        resolver - the ParameterResolver
        Returns:
        the high units

      • setHighUnits

        @Injectable
public void setHighUnits​(Expression<Units> expr)
        Set the high units.
        Parameters:
        expr - the high units expression

      • getUnitCalculatorBuilder

        public UnitCalculatorBuilder getUnitCalculatorBuilder()
        Return the UnitCalculatorBuilder used to build a UnitCalculator.
        Returns:
        the unit calculator

      • setUnitCalculatorBuilder

        @Injectable("unit-calculator")
public void setUnitCalculatorBuilder​(UnitCalculatorBuilder builder)
        Set the UnitCalculatorBuilder.
        Parameters:
        builder - the UnitCalculatorBuilder

      • getUnitFactor

        public int getUnitFactor​(ParameterResolver resolver)
        Return the unit-factor element specifies the factor by which the units, low-units and high-units properties are adjusted. Using a BINARY unit calculator, for example, the factor of 1048576 could be used to count megabytes instead of bytes.
        Parameters:
        resolver - the ParameterResolver
        Returns:
        the unit factor

      • setUnitFactor

        @Injectable
public void setUnitFactor​(Expression<Integer> expr)
        Set the unit factor.
        Parameters:
        expr - the unit factor expression
