areCompatible

protected boolean areCompatible(JNode sourceNode,
                                JNode targetNode)

Checks if two nodes are compatible and can be merged.

This method must always return false if target node can have children that can not be added to source node.

Parameters:

sourceNode -

targetNode -

Returns:

true if nodes can be merged, false otherwise

convertTarget

protected JNode convertTarget(JAbstractType targetAbstractType,
                              java.lang.Class<? extends JAbstractType> sourceClass)

Converts the target abstract type to be compatible with the given source node class

Parameters:

targetAbstractType -

sourceClass - the class to which to convert the node.

Returns:

null when conversion not possible, converted node otherwise

insertClone

protected JNode insertClone(JNode sourceNode)

isPushMarkedUp

protected boolean isPushMarkedUp(JNode node)

Checks if the node is marked up for pushing.

Node is considered marked up by default if there are no push rules for this node class.

The first push rule that matches the node makes the node marked up, and no further checking is performed.

If the push rule does not match the node, but the push rule is defined for the same node class, then the node will not be marked up, unless any of the following push rules will match the node.

Parameters:

node -

Returns:

true if node should be pushed, false otherwise

map

protected void map(JNode sourceNode,
                   JNode targetNode)

Maps the specified source and target nodes.

Parameters:

sourceNode -

targetNode -

mapChildren

protected void mapChildren(JNode sourceNode,
                           JNode targetNode)

run

public java.lang.Object run(java.lang.Object object)

This is called with the command line arguments of a headless workbench invocation.

execute

public java.lang.String execute(Monitor monitor,
                                java.lang.String[] arguments)

Utility for headless operations.

Returns:

the merged content.
