findEditedProposition

public static Node<RuleEditorTreeNode,String> findEditedProposition(Node<RuleEditorTreeNode,String> node)

Find and return the node containing the proposition that is in currently in edit mode

Parameters:

Returns:

the node that is currently being edited, if any. Otherwise, null.

resetEditModeOnPropositionTree

public static boolean resetEditModeOnPropositionTree(PropositionEditor proposition)

disable edit mode for all Nodes beneath and including the passed in Node

Parameters:

Builds a logical string expression from the proposition tree.

Parameters:

proposition -

Returns:

createSimplePropositionBoStub

public static PropositionEditor createSimplePropositionBoStub(PropositionEditor sibling,
                                              Class<? extends PropositionEditor> propClass)
                                                       throws IllegalAccessException,

This method creates a partially populated Simple PropositionBo with three parameters: a term type paramter (value not assigned) a operation parameter a constant parameter (value set to empty string) The returned PropositionBo has an generatedId. The type code and ruleId properties are assigned the same value as the sibling param passed in. Each PropositionParameter has the id generated, and type, sequenceNumber, propId default values set. The value is set to "".

Parameters:

sibling - -

Returns:

a PropositionBo partially populated.

Throws:

IllegalAccessException

InstantiationException
