Method Detail

addKey

@NotNull
public net.corda.core.crypto.CompositeKey.Builder addKey(@NotNull
                                                                  java.security.PublicKey key,
                                                                  int weight)

Adds a child class CompositeKey node. Specifying a weight for the child is optional and will default to 1.

                                                                   java.security.PublicKey... keys)

                                                                   java.util.List<? extends java.security.PublicKey> keys)

build

@NotNull
public java.security.PublicKey build(@Nullable
                                              java.lang.Integer threshold)

Builds the class CompositeKey. If threshold is not specified, it will default to the total (aggregated) weight of the children, effectively generating an "N of N" requirement. During process removes single keys wrapped in class CompositeKey and enforces ordering on child nodes.

Parameters:

threshold - specifies the minimum total weight required (in the simple case – the minimum number of childsignatures required) to satisfy the sub-tree rooted at this node.

Throws:

IllegalArgumentException - if the threshold value is invalid.

IllegalStateException - if the composite key that would be generated from the current state of the builder is invalid (for example it would contain no keys).
