StoreSettings

public StoreSettings(Application application)

Construct.

Parameters:

application -

Method Detail

getInmemoryCacheSize

public int getInmemoryCacheSize()

Returns:

the number of page instances which will be stored in the application scoped cache for faster retrieval

setInmemoryCacheSize

public StoreSettings setInmemoryCacheSize(int inmemoryCacheSize)

Sets the maximum number of page instances which will be stored in the application scoped second level cache for faster retrieval

Parameters:

inmemoryCacheSize - the maximum number of page instances which will be held in the application scoped cache

Returns:

this object for chaining

getMaxSizePerSession

public Bytes getMaxSizePerSession()

Returns:

maximum page size. After this size is exceeded, the DiskDataStore will start saving the pages at the beginning of file.

setMaxSizePerSession

public StoreSettings setMaxSizePerSession(Bytes maxSizePerSession)

Sets the maximum size of the File where page instances per session are stored. After reaching this size the DiskDataStore will start overriding the oldest pages at the beginning of the file.

Parameters:

maxSizePerSession - the maximum size of the file where page instances are stored per session. In bytes.

Returns:

this object for chaining

getFileStoreFolder

public File getFileStoreFolder()

Returns:

the location of the folder where DiskDataStore will store the files with page instances per session

setFileStoreFolder

public StoreSettings setFileStoreFolder(File fileStoreFolder)

Sets the folder where DiskDataStore will store the files with page instances per session

Parameters:

fileStoreFolder - the new location

Returns:

this object for chaining

getAsynchronousQueueCapacity

public int getAsynchronousQueueCapacity()

Returns:

the capacity of the queue used to store the pages which will be stored asynchronously

See Also:

AsynchronousDataStore

setAsynchronousQueueCapacity

public StoreSettings setAsynchronousQueueCapacity(int queueCapacity)

Sets the capacity of the queue used to store the pages which will be stored asynchronously

Parameters:

queueCapacity - the capacity of the queue

Returns:

this object for chaining

See Also:

AsynchronousDataStore

setAsynchronous

public StoreSettings setAsynchronous(boolean async)

Sets a flag whether to wrap the configured IDataStore with AsynchronousDataStore. By doing this the HTTP worker thread will not wait for the actual write of the page's bytes into the wrapped IDataStore.

Parameters:

async - true to make it asynchronous, false - otherwise

Returns:

this object for chaining

isAsynchronous

public boolean isAsynchronous()

Returns:

true if the storing of page's bytes is asynchronous
