parseUnits

public static String parseUnits(org.antlr.v4.runtime.tree.ParseTree ctx)

Parse given tree and returns units statement as string.

Parameters:

ctx - context to parse

Returns:

value of units statement as string or null if there is no units statement

parseDefault

public static String parseDefault(org.antlr.v4.runtime.tree.ParseTree ctx)

Parse given tree and returns default statement as string.

Parameters:
