Method Detail

copyTree

static java.util.Map<java.lang.String,java.lang.Object> copyTree(java.util.Map<java.lang.String,java.lang.Object> srcTree)

Deep copy the tree implemented as map of maps/leafs

Parameters:

srcTree - the source tree

Returns:

the tree copy

addBranches

static java.util.Map<java.lang.String,java.lang.Object> addBranches(java.util.Map<java.lang.String,java.lang.Object> dst,
                                                                    java.util.Map<java.lang.String,java.lang.Object> src)

reduceForest

static java.util.Map<java.lang.String,java.lang.Object> reduceForest(java.util.List<java.util.Map<java.lang.String,java.lang.Object>> forest)
