Constructor Detail

ComputedNode

public ComputedNode(java.lang.String key,
                    java.lang.String[] sourceNodesKeys,
                    Computation computation)

Constructor.

Parameters:

key - the key of the node

sourceNodesKeys - the keys of the nodes that the computation depends on

computation - the computation (not null)

Method Detail

getComputation

public Computation getComputation()

Returns:

the computation used to compute the value

collectSystemInfo

public void collectSystemInfo(SystemInfoNode root,
                              SystemInfoOptions options)

Description copied from interface: SystemInfoProvider

Builds the system information tree upon local information of the implementor. The system information tree can be used within development by inspecting the system; so implementors should append their internal state (depending on the details settings within SystemInfoOptions). The information can be appended to the tree by adding new child SystemInformationNodes to the root node given using the SystemInfoNode.createChild(String) method and by setting information attributes the these nodes or the given root node.

Specified by:

collectSystemInfo in interface SystemInfoProvider

Overrides:

collectSystemInfo in class Node
