Method Detail

getBaseDirectory

@ManagedAttribute(description="The base directory")
public File getBaseDirectory()

setBaseDirectory

public void setBaseDirectory(File baseDir)

Sets the location of the jadice server's working directory

Parameters:

baseDir - the base directory to use

getSize

@ManagedMetric(description="Size of the working directory",
               metricType=GAUGE,
               unit="Bytes")
public BigInteger getSize()

Counts the size of the working directory recursively (sum of the length of all files).

Returns:

Size of the working directory in bytes

getNumberOfFiles

@ManagedMetric(description="Number of files in the working directory",
               metricType=GAUGE)
public int getNumberOfFiles()

Counts the number of all files in the working directory recursively

Returns:

The number of files

purge

@ManagedOperation(description="Purges the working directory. Use carefully!")
public void purge()
           throws IOException

Purges the temp directory. Be careful not to remove stuff we are't supposed to remove, if baseDir is mis-configured. We do this by checking whether a marker file exists.

This operation does not consider if there are Jobs in progress that need a file which is stored in this working directory

Throws:

IOException - if the marker file cannot be (re-)created.

getObjectName

public ObjectName getObjectName()
                         throws MalformedObjectNameException

Specified by:

getObjectName in interface org.springframework.jmx.export.naming.SelfNaming

Throws:

MalformedObjectNameException

start

public void start()

Specified by:

start in interface org.springframework.context.Lifecycle

stop

public void stop()

Specified by:

stop in interface org.springframework.context.Lifecycle

isRunning

public boolean isRunning()

Specified by:

isRunning in interface org.springframework.context.Lifecycle

isPurgeOnStart

@ManagedAttribute(description="Purge the working directory on start")
public boolean isPurgeOnStart()

Returns:

true iff the working directory is purged on start

setPurgeOnStart

public void setPurgeOnStart(boolean purgeOnStart)

isPurgeOnStop

@ManagedAttribute(description="Purge the working directory on shutdown")
public boolean isPurgeOnStop()

Returns:

true iff the working directory shall be purged on shutdown

setPurgeOnStop

@ManagedAttribute
public void setPurgeOnStop(boolean purgeOnStop)

Set if the working directory shall be purged on shutdown

Parameters:

purgeOnStop - if true the working directory shall be purged
