Description copied from interface: Transaction.OptionMetadata

Updates the options map of a child transaction to inherit the setting in a parent transaction, if it is a hereditary option and the child does not already have a setting for it.

Specified by:: inherit in interface Transaction.OptionMetadata
Overrides:: inherit in class BasicTransactionOptionMetadata

Parameters:: parentOptions - the options map to inherit a value from. It is conceivable that inheritance of an option may depend on more than one option in this parent map; childOptions - the map that is to inherit the option setting; force - whether to inherit the option anyway despite that it is not hereditary. This is used for application of default options, and can be ignored by the implementor if necessary. Also, clients must not use this parameter to attempt to override an existing child setting; a well-behaved option will not do that
