protected java.io.Reader createReader(java.net.URL url)

Overriden to return a Reader based on the merge node's text buffer.

Overrides:

createReader in class TextNode

Parameters:

url - ignored.

Returns:

a reader on the merge node's text.

setReadOnly

public boolean setReadOnly(boolean readOnly)

Overriden to control the read-only state.

Overrides:

setReadOnly in class Node

Parameters:

readOnly - ignored.

Returns:

true, always.

isTrackedInNodeCache

protected boolean isTrackedInNodeCache()

Overriden to prevent the merge node from being cached.

Overrides:

isTrackedInNodeCache in class Node

Returns:

false, always.

saveImpl

protected void saveImpl()

Overriden to prevent I/O from an attempted save.

Overrides:

saveImpl in class TextNode

getIcon

public javax.swing.Icon getIcon()
