Interface BackupMapConfig

All Superinterfaces:

BuilderCustomization<Map>

All Known Implementing Classes:

DistributedScheme.BackupConfig

public interface BackupMapConfig
extends BuilderCustomization<Map>

The BackupMapConfig interface exposes the configuration needed to create an instance of a backup map, which is used by the distributed cache to store backup data.

Method Detail

resolveType

int resolveType(com.tangosol.config.expression.ParameterResolver resolver,
                MapBuilder bldrPrimaryMap)

Resolve the backup map type using the configuration specified by the application. The primary map is also need in special cases to determine the type.

Parameters:

resolver - the ParameterResolver

bldrPrimaryMap - the primary map builder which may be used to determine the backup type

Returns:

the backup map type enumerated in BackingMapScheme

getBackupSchemeName

String getBackupSchemeName(com.tangosol.config.expression.ParameterResolver resolver)

Return the name of the caching scheme to use as a backup map. Note that the scheme name is used as a key to lookup the scheme in the cache mapping. This is in contrast with the scheme name in the base AbstractScheme class which self-identifies a scheme object.

Parameters:

resolver - the ParameterResolver

Returns:

the scheme name

getDirectory

String getDirectory(com.tangosol.config.expression.ParameterResolver resolver)

Return the root directory where the disk persistence manager stores files. This is only valid for file-mapped type.

Parameters:

resolver - the ParameterResolver

Returns:

the root directory

getInitialSize

int getInitialSize(com.tangosol.config.expression.ParameterResolver resolver)

Return the initial buffer size in bytes for off-heap and file-mapped backup maps.

Parameters:

resolver - the ParameterResolver

Returns:

the write maximum batch size

getMaximumSize

int getMaximumSize(com.tangosol.config.expression.ParameterResolver resolver)

Return the maximum buffer size in bytes for off-heap and file-mapped backup maps.

Parameters:

resolver - the ParameterResolver

Returns:

the write maximum buffer size
