Code executed inside a block passed to this method may read and write data to and from the data store file. - !ruby/struct:SM::Flow::P body: At the end of the block, changes are committed to the data store automatically. You may exit the transaction early with a call to either PStore#commit or PStore#abort. See those methods for details about how changes are handled. Raising an uncaught Exception in the block is equivalent to calling PStore#abort. - !ruby/struct:SM::Flow::P body: If <em>read_only</em> is set to <tt>true</tt>, you will only be allowed to read from the data store during the transaction and any attempts to change the data will raise a PStore::Error. - !ruby/struct:SM::Flow::P body: Note that PStore does not support nested transactions. full_name: PStore#transaction is_singleton: false name: transaction params: (read_only=false) {|pstore| ...} visibility: public
