valid_str(addr)
Returns: True if EUI-64 indentifier is valid, False otherwise.

str_to_int(addr)
Returns: An unsigned integer that is equivalent to value represented by EUI-64 string identifier.

valid_str(addr)

Parameters:

addr - An IEEE EUI-64 indentifier in string form.

Returns:

True if EUI-64 indentifier is valid, False otherwise.

str_to_int(addr)

Parameters:

addr - An IEEE EUI-64 indentifier in string form.

Returns:

An unsigned integer that is equivalent to value represented by EUI-64 string identifier.

int_to_str(int_val, dialect=None)

Parameters:

int_val - An unsigned integer.
dialect - (optional) a Python class defining formatting options (Please Note - not currently in use).

Returns:

An IEEE EUI-64 identifier that is equivalent to unsigned integer.

int_to_packed(int_val)

Parameters:

int_val - the integer to be packed.

Returns:

a packed string that is equivalent to value represented by an unsigned integer.

packed_to_int(packed_int)

Parameters:

packed_int - a packed string containing an unsigned integer. It is assumed that string is packed in network byte order.

Returns:

An unsigned integer equivalent to value of network address represented by packed binary string.
