Method Detail

setNode

public static void setNode(net.sf.json.JSONObject source,
                           String path,
                           Object value)

Set the value of the node for the given path.

Parameters:

source -

path -

value -

setNode

public static void setNode(net.sf.json.JSONObject source,
                           String[] path,
                           Object value)

Contract is that if the path is /a/b/.../c/d then the result is node d has the given value, replacing what was there, if applicable.

Parameters:

source -

path -

value -

appendNode

public static void appendNode(net.sf.json.JSONObject source,
                              String[] path,
                              Object value)

Used in the case of /a/b.../d where d is an array. This appends the value as the next element of d.

Parameters:

value -

getNextToLastNode

public static net.sf.json.JSON getNextToLastNode(net.sf.json.JSONObject source,
                                                 String path)

Go to the given node and return

Parameters:

source -

path - - the raw path to the node

Returns:

getNextToLastNode

public static net.sf.json.JSON getNextToLastNode(net.sf.json.JSON j,
                                                 String[] path)

This will return the next to last node for a pathh

Parameters:

j -

path -

Returns:

getNodeDropIndex

protected static net.sf.json.JSON getNodeDropIndex(net.sf.json.JSON j,
                                                   String[] path,
                                                   int numberOfComponentsToDrop)

getNode

public static net.sf.json.JSON getNode(net.sf.json.JSON j,
                                       String[] path)
