Method Detail

clearAllGreaterThen

@ManagedOperation(description="Clears all cache entry\'s that size is greater that minSize parameter.")
@ManagedOperationParameters(value=)
public final boolean clearAllGreaterThen(long minSize)

Clears all cache entry's that size is greater that minSize parameter.

This operation will stops clearing elements after first failure, this means that it will clear all cache entry's until one of that entry's fails to clear.

Parameters:

minSize - Minimal size (in bytes) of cache entry that should be cleaned.

Returns:

true if operation ends with success, false otherwise

clearAllSmallerThen

@ManagedOperation(description="Clears all cache entry\'s that size is smaller than maxSize parameter.")
@ManagedOperationParameters(value=)
public final boolean clearAllSmallerThen(long maxSize)

Clears all cache entries whose size is smaller than maxSize parameter.

This operation will stops clearing elements after first failure, this means that it will clear all cache entry's until one of that entry's fails to clear.

Parameters:

maxSize - Maximum size (in bytes) of cache entry that should be cleaned.

Returns:

true if operation ends with success, false otherwise

clearAllOlderThen

@ManagedOperation(description="Clears all cache entry\'s that are older than baseDate parameter.")
@ManagedOperationParameters(value=)
public final boolean clearAllOlderThen(String baseDate)

Clears all cache entry's that are older than baseDate parameter.

This operation will stops clearing elements after first failure, this means that it will clear all cache entry's until one of that entry's fails to clear.

Parameters:

baseDate -

Returns:

true if operation ends with success, false otherwise

clearAllYoungerThen

@ManagedOperation(description="Clears all cache entry\'s that are younger than baseDate parameter.")
@ManagedOperationParameters(value=)
public final boolean clearAllYoungerThen(String baseDate)

Clears all cache entry's that are younger than baseDate parameter.

This operation will stops clearing elements after first failure, this means that it will clear all cache entry's until one of that entry's fails to clear.

Parameters:

baseDate -

Returns:

true if operation ends with success, false otherwise

clear

@ManagedOperation(description="Clears all cache entry\'s that matches all conditions in parameters. All parameters are connected logical AND, so to perform action cache entry should match all conditions at once.")
@ManagedOperationParameters(value={,,,,,})
public final boolean clear(long minSize,
                                                                       long maxSize,

                                                                       String maxLastModifiDate,
                                                                       String minExpiresDate,
                                                                       String maxExpiresDate)

Clears all cache entry's that matches all conditions in parameters. All parameters are connected logical AND, so to perform action cache entry should match all conditions at once.

This operation will stops clearing elements after first failure, this means that it will clear all cache entry's until one of that entry's fails to clear.

Parameters:

minSize - Minimal size (in bytes) of cache entry that should be cleaned. If value of this parameter < 0 then it isn't consider.

maxSize - Maximum size (in bytes) of cache entry that should be cleaned. If value of this parameter < 0 then it isn't consider.

minLasModifyDate - If this parameter is null or is empty it isn't consider.

maxLasModifyDate - If this parameter is null or is empty it isn't consider.

minExpiresDate - This parameter apply's only to ExpiresCacheKey entry's. If this parameter is null or is empty it isn't consider.

maxExpiresDate - This parameter apply's only to ExpiresCacheKey entry's. If this parameter is null or is empty it isn't consider.

Returns:

true if operation ends with success, false otherwise
