axisDayadRecursion
public static void axisDayadRecursion(QDLStem out0, QDLStem left0, QDLStem right0, int depth, boolean maxDepth, StemUtility.DyadAxisAction axisAction)
Apply some action along an axis. This will recurse to a given axis and apply an action there- Parameters:
out0
-left0
-right0
-depth
-maxDepth
-axisAction
-
-
axisWalker
public static Object axisWalker(QDLStem inStem, int depth, StemUtility.StemAxisWalkerAction1 walker)
Recurses through stem that has arbitrary rank.- Parameters:
inStem
-depth
-walker
-- Returns:
-
doNodeSurgery
public static void doNodeSurgery(ExpressionStemNode ESN, State state)
-
formatList
public static void formatList(QDLStem stem)
-
main
public static void main(String[] args)

stemListToString
public static String stemListToString(QDLStem contents, boolean forceToString)
Convert a stem list to a string, separated by line feeds. IfforceToString
is true, then every elements toString is called, otherwise, if the element is not a string, an exception is thrown.- Parameters:
contents
