Detailed Description

assert that some conditions are true.

This operation performs no changes to the database state, but can but used to verify pre or post conditions for other operations.

Member Function Documentation

share_type graphene::protocol::assert_operation::calculate_fee ( const fee_parameters_type k) const

The fee for assert operations is proportional to their size, but cheaper than a data fee because they require no storage
