Method Detail

realizeMap

public java.util.Map realizeMap(com.tangosol.config.expression.ParameterResolver resolver,
                                MapBuilder.Dependencies dependencies)

Realize a Map based on the state of the MapBuilder, resolvable parameters and provided MapBuilder.Dependencies.

Specified by:

realizeMap in interface MapBuilder

Overrides:

realizeMap in class AbstractCachingScheme

Parameters:

resolver - the ParameterResolver

dependencies - the MapBuilder.Dependencies for realizing the Map

Returns:

a Map

getBinaryStoreManagerBuilder

public BinaryStoreManagerBuilder getBinaryStoreManagerBuilder()

Obtains the BinaryStoreManagerBuilder for the BinaryStoreManager.

Specified by:

getBinaryStoreManagerBuilder in interface BinaryStoreManagerBuilderCustomization

Returns:

the BinaryStoreManagerBuilder

setBinaryStoreManagerBuilder

public void setBinaryStoreManagerBuilder(BinaryStoreManagerBuilder bldr)

Sets the BinaryStoreManagerBuilder for the BinaryStoreManager.

Specified by:

setBinaryStoreManagerBuilder in interface BinaryStoreManagerBuilderCustomization

Parameters:

bldr - the BinaryStoreManagerBuilder

getExpiryDelay

public Seconds getExpiryDelay(com.tangosol.config.expression.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(com.tangosol.config.expression.Expression expr)

Set the expiry delay.

Parameters:

expr - the expiry delay expression

getHighUnits

public Units getHighUnits(com.tangosol.config.expression.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(com.tangosol.config.expression.Expression 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(value="unit-calculator")
public void setUnitCalculatorBuilder(UnitCalculatorBuilder bldr)

Set the UnitCalculatorBuilder.

Parameters:

bldr - the UnitCalculatorBuilder

getUnitFactor

public int getUnitFactor(com.tangosol.config.expression.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(com.tangosol.config.expression.Expression expr)

Set the unit factor.

Parameters:

expr - the unit factor expression
