Constructor Detail

Node

protected Node(java.lang.String key,
               java.lang.Class type)

Creates a node without dependencies

Parameters:

key - the key of the node

type - the type of the value that this node represents

Node

protected Node(java.lang.String key,
               java.lang.String[] sourceNodesKeys,
               java.lang.Class type)

Creates a node that depends on other nodes. Note the source nodes will be stored as reference so the given array must not be modified.

Parameters:

key - the key of the node

sourceNodesKeys - the keys of the nodes that this node depends on

type - the type of the value that this node represents

Method Detail

getKey

public java.lang.String getKey()

Returns:

the key of this node

getSourceNodeKeys

public java.lang.String[] getSourceNodeKeys()

Returns:

the keys of the nodes that this node depends on

getType

public java.lang.Class getType()

Returns:

the type of the value that this node represents

toString

public java.lang.String toString()

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

Parameters:

root - the SystemInfoNode to add information to (guaranteed to be not null)

options - contains additional options, that might influence the amount of information added to the tree (guaranteed to be not null)
