Constructor Detail

RdrTree

public RdrTree()

Default constructor

RdrTree

public RdrTree(java.lang.String taskId)

Constructs an empty tree

Parameters:

taskId - - id of task that this tree will support

Method Detail

getRootNode

public RdrNode getRootNode()

getTaskId

public java.lang.String getTaskId()

getNode

public RdrNode getNode(long id)

Gets the RdrNode for the id passed

Parameters:

id - - the node id of the node to find

Returns:

the node identified by the id, or null if this tree has no matching node

getAllConditions

public java.util.List<java.lang.String> getAllConditions()

Gets the condition of each node in this tree

Returns:

a List of all node conditions

getAllConditions

public java.util.List<java.lang.String> getAllConditions(RdrNode node)

Recurses the tree, collecting the condition from each node

Parameters:

node - the root node of this (sub)-tree

Returns:

a List of all node conditions

getAttributes

protected YAttributeMap getAttributes()

setRootNode

public void setRootNode(RdrNode root)

setTaskId

public void setTaskId(java.lang.String id)

setAttributes

public void setAttributes(java.lang.String processName,
                          RuleType rType)

setAttributes

public void setAttributes(YSpecificationID specID,
                          RuleType rType)

search

public RdrPair search(Element caseData)

evaluates the conditions of each transversed node in this tree

Parameters:

caseData - - a JDOM Element that contains the set of data attributes and values that are used to evaluate the conditional expressions

Returns:

the pair of nodes resulting from the rule evaluation

createRootNode

public RdrNode createRootNode()

addNode

public RdrNode addNode(RdrNode newNode,
                       RdrNode parentNode,
