Method Detail

getUuid

String getUuid()

Get this node's UUID.

Returns:

the uuid as a string.

getSystemInformation

JPPFSystemInformation getSystemInformation()

Get the system information for this node.

Returns:

a JPPFSystemInformation instance.

isLocal

boolean isLocal()

Determine whether this node is local to another component.

Returns:

true if this node is local, false otherwise.

resetTaskClassLoader

ClassLoader resetTaskClassLoader(Object... params)

Reset the current task class loader if any is present (i.e. if a job is being executed), without reconnecting to the server.

Parameters:

params - a (possibly empty) set of arbitrary parameters to propagate to the class loader.

Returns:

the newly created class loader, or null if none could be created at this time. This class loader can be safely cast to an AbstractJPPFClassLoader.

isOffline

boolean isOffline()

Determine whether this node is running in offline mode.

Returns:

true if this node is offline, false otherwise.

isMasterNode

boolean isMasterNode()

Determine whether this node is a 'master' node for the provisioning features.

Returns:

true if this node is a master, false otherwise.

isSlaveNode

boolean isSlaveNode()

Determine whether this node is a 'slave' node for the provisioning features.

Returns:

true if this node is a slave, false otherwise.

getMasterNodeUuid

String getMasterNodeUuid()

Get the uuid of the node who this node is a slave of.

Returns:

the uuid of this node's master node, or null if this node is not a slave.

Since:

6.0

isDotnetCapable

boolean isDotnetCapable()

Determine whether this node can execute .Net tasks.

Returns:

true if this node can execute .Net tasks, false otherwise.

isAndroid

boolean isAndroid()

Determine whether this node is an Android node.

Returns:

true if this node runs on Android, false otherwise.

getConfiguration

TypedProperties getConfiguration()

Get the configuration of this node.

Returns:

the node configuration as a TypedProperties instance.

getManagementInfo

JPPFManagementInfo getManagementInfo()

Get the management information for this node.

Returns:

a JPPFManagementInfo object.

getExecutedTaskCount

int getExecutedTaskCount()

Get the total number of tasks executed.

Returns:

the number of tasks as an int.
