Function registerMutator

registerMutator(
    name: string,
    mixinObj: Object,
    opt_helperFn?: () => any,
    opt_blockList?: string[],
): void
Registers a new extension function that adds a mutator to the block. At register time this performs some basic sanity checks on the mutator. The wrapper may also add a mutator dialog to the block, if both compose and decompose are defined on the mixin.
Parameters
- name: string
  The name of this mutator extension.
- mixinObj: Object
  The values to mix in.
- Optionalopt_helperFn: () => any
  An optional function to apply after mixing in the object.
- Optionalopt_blockList: string[]
  A list of blocks to appear in the flyout of the mutator dialog.
Returns void
Throws
if the mutation is invalid or can't be applied to the block.
