assign one char to another

@returns true if sealed - in this case you can no longer append transactions.

Export a list of items in RLP format, returning a byte array.

@returns the number of elements referenced (not necessarily number of bytes).

@return Size of repository

Swap the contents of the output stream out for some other byte array.

Converts byte array to a string containing the same (binary) data. Unless the byte array happens to contain ASCII data, this won't be printable.

Securely overwrite the memory. @note adapted from OpenSSL's implementation.

Force the sender to a particular value. This will result in an invalid transaction RLP.

@returns the nonce of the account.

copy n chars from s2 to s1

create the directory path by container

Implement these in the derived class. static std::string name() { return ""; } static u256 version() { return 0; } static unsigned messageCount(

@param host the host to set

@param port the port to set

Collect execution results in the result storage provided.

Interprets @a _u as a two's complement signed number and returns the resulting s256.

* Encode length in DER format (if length <0x80, then one byte, else first byte is 0x80 + length of length :) + n-bytes of length).
