Method Details

settings

public <V> ConcurrentMap<String,V> settings(String key)

Description copied from interface: TransientSettingDao

Get the settings map for a given key.

This method will always return the same map instance for a given key.

Specified by:

settings in interface TransientSettingDao

Type Parameters:

V - the value type to cast to; note this is only a generic casting operation for convenience and the actual map is expected to actually be declared as ConcurrentMap&ltString, Object>

Parameters:

key - the settings key to get

Returns:

the settings for the given key, never null

getSettingsInitialCapacity

public int getSettingsInitialCapacity()

Get the initial capacity used for settings maps.

Returns:

the initial capacity; defaults to DEFAULT_SETTINGS_INITIAL_CAPACITY

setSettingsInitialCapacity

public void setSettingsInitialCapacity(int settingsInitialCapacity)

Set the initial capacity used for settings maps.

Parameters:

settingsInitialCapacity - the capacity to set

getSettingsLoadFactor

public float getSettingsLoadFactor()

Get the load factory used for settings maps.

Returns:

the load factor; defaults to DEFAULT_SETTINGS_LOAD_FACTOR

setSettingsLoadFactor

public void setSettingsLoadFactor(float settingsLoadFactor)

Set the load factory used for settings maps.

Parameters:

settingsLoadFactor - the load factor to set

getSettingsConcurrencyLevel

public int getSettingsConcurrencyLevel()

Get the concurrency level used for settings maps.

Returns:

the concurrency level; defaults to DEFAULT_SETTINGS_CONCURRENCY_LEVEL

setSettingsConcurrencyLevel

public void setSettingsConcurrencyLevel(int settingsConcurrencyLevel)

Set the concurrency level used for settings maps.

Parameters:

settingsConcurrencyLevel - the concurrency level to set
