fun build(threshold: Int? = null): PublicKey
Builds the 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 CompositeKey and enforces ordering on child nodes.
threshold
- specifies the minimum total weight required (in the simple case – the minimum number of child
signatures required) to satisfy the sub-tree rooted at this node.
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).
