Types ¶
type BankAccount ¶
Represents a UK bank account
func CreateBankAccount ¶
func CreateBankAccount(sortCode, accountNumber string) BankAccount
Create a BankAccount structure from a sort code and an account number
func (BankAccount) AccountNumberSlice ¶
func (b BankAccount) AccountNumberSlice() []int
The account number has an integers slice
func (BankAccount) MergeAccountDetails ¶
func (b BankAccount) MergeAccountDetails() []int
Merge the sort code and the account number of a bank account into a single slice
func (BankAccount) NumberAtPosition ¶
func (b BankAccount) NumberAtPosition(letter string) int
NumberAtPosition gets the integer value from a letter, according to the defined code: Letters between u and z select a digit from the sort code Letters between a and h select a digit from the account number
func (BankAccount) SortCodeSlice ¶
func (b BankAccount) SortCodeSlice() []int
The sort code has an integers slice
type Checker ¶
type Checker interface {
// Determine if the checker is able to validate the bank account
Handles(b BankAccount, sc SortCodeData, attempt int) bool
// Tell if the bank account is valid
IsValid(b BankAccount, sc SortCodeData, attempt int) bool
}
A checker is in charge of validating a bank account number
type Parser ¶
type Parser interface {
// Read the weights, exception information and algorithm to use for sort code ranges.
Weights() map[string]SortCodeData
// Give a list of sort code substitutions
Substitutions() map[string]string
}
A parser should be able to: - read the weights, exception information and algorithm to use for sort code ranges. - give a list of sort code substitutions.
type SortCodeData ¶
type SortCodeData struct {
// The algorithm to use:
// - DBLAL: double alternate check
// - MOD10: modulus with a modulus of 10
// - MOD11: modulus with a modulus of 11
Algorithm string
// Weights to use for the sort code and the account number
Weights []int
// The exception value. If 0, the sort code does not have an exception.
ExceptionValue int
// If a sort code follows multiple rule, Next will not be nil.
Next *SortCodeData
// Indicates the line number where this rule was stored in the file.
LineNumber int
}
Give information about a sort code
func (SortCodeData) FollowsExceptions ¶
func (s SortCodeData) FollowsExceptions(ex1, ex2 int) bool
FollowsExceptions checks if a sort code follows 2 exceptions.
func (SortCodeData) HasException ¶
func (s SortCodeData) HasException() bool
HasException Does this sort code has got an exception?
func (SortCodeData) HasNext ¶
func (s SortCodeData) HasNext() bool
HasNext Does this sort code follows another rule?
func (SortCodeData) IsException ¶
func (s SortCodeData) IsException(exceptionValue int) bool
IsException checks if a sort code follows an exception.
type SortCodeRange ¶
type SortCodeRange struct {
// Beginning of the sort code range.
Start int
// End of the sort code range.
End int
// The algorithm to use:
// - DBLAL: double alternate check
// - MOD10: modulus with a modulus of 10
// - MOD11: modulus with a modulus of 11
Algorithm string
// Weights to use for the sort code and the account number
Weights []int
// The exception value. If 0, the sort code does not have an exception.
ExceptionValue int
// Indicates the line number where this rule was stored in the file.
LineNumber int
}
This structure describes a sort code range, starting from a sort code and ending to another.
func (SortCodeRange) HasException ¶
func (sc SortCodeRange) HasException() bool
HasException checks if a sort code range has got an exception
