Method Detail

transpose

public static <T> LogicTree<List<T>> transpose(List<LogicTree<T>> treeList)

Transpose a list of logic trees to a new logic tree of immutable lists. Supplied logic trees are assumed to all have same branch names, IDs and weights.

Type Parameters:

T - the value type of the supplied logic tree

Parameters:

treeList - the list of logic trees to transpose

transform

public static <T,R> LogicTree<R> transform(LogicTree<T> tree,
                                                 Function<T,R> function,
                                                 Optional<String> name)

Transform a logic tree with one value type into a new logic tree with a different value type, preserving branch IDs and weights.

Type Parameters:

T - the value type of the supplied logic tree

R - the value type of the transformed logic tree

Parameters:

tree - to transform

function - to apply

name - optional new name for the transformed tree; if empty the name of the supplied tree is used
