问题 I do have a getter/setter for the Date variable, like so: private Date registrationDate; @TypeConversion(converter = "org.com.helper.DataHelper") public Date getRegistrationDate() { return registrationDate; } @TypeConversion(converter = "org.com.helper.DataHelper") public void setRegistrationDate(Date registrationDate) { this.registrationDate = registrationDate; } As you can see I've created a custom struts converter to convert the incoming string to the Date format and then assign it.

问题 I am trying to analyse MIDI files using a toolkit python-midi for python (link to the repo). Basically, my question is about the interpretation of the data I just extracted.

问题 Reference: Is there a faster way of converting a number to a name? In the question referenced above, a solution was found for turning a numbe into a name. This question asks just the opposite. How can you convert a name back into a number? So far, this is what I have: >>> import string >>> HEAD_CHAR = ''.join(sorted(string.ascii_letters + '_')) >>> TAIL_CHAR = ''.join(sorted(string.digits + HEAD_CHAR)) >>> HEAD_BASE, TAIL_BASE = len(HEAD_CHAR), len(TAIL_CHAR) >>> def number_to_name(number):
