Constructor Detail

AspectNode

public AspectNode(java.lang.String key,
                  java.lang.String sourceKey,
                  java.lang.Class sourceType,
                  java.lang.String aspectName,
                  java.lang.Class type)

Constructor.

Parameters:

key - the key of the node

sourceKey - the key of the node that provides the source value for the aspect

sourceType - the type of object that this aspect node expects as source value

aspectName - the name of the aspect which is usually the name of the attribute

type - the type of the value that this node represents

Method Detail

getValue

public java.lang.Object getValue(java.lang.Object sourceValue)

Reads the aspect using the getter method or a public member variable

Parameters:

sourceValue - the source value

Returns:

the value of the aspect

canModify

public boolean canModify()

Returns:

true when the aspect of the node can be modified

setValue

public void setValue(java.lang.Object sourceValue,
                     java.lang.Object aspectValue)

Writes the aspect using the setter method

Parameters:

sourceValue - the source value

aspectValue - the attribute value to set

getSourceType

public java.lang.Class getSourceType()

Returns:

the type of object that this aspect node expects as source 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
