Method Detail

afterPropertiesSet

public void afterPropertiesSet()

generateClearText

public java.lang.String generateClearText(MultiCodeCouponModel coupon,
                                          int length)

Description copied from interface: CouponCodeClearTextGenerationStrategy

returns the generated clear-text part of the coupon code with the given length

Specified by:

generateClearText in interface CouponCodeClearTextGenerationStrategy

getCouponCodeNumberForClearText

public long getCouponCodeNumberForClearText(MultiCodeCouponModel coupon,
                                            java.lang.String clearText)

Description copied from interface: CouponCodeClearTextGenerationStrategy

returns the original coupon code number the given clearText was based on. (This is the inverse function to the CouponCodeClearTextGenerationStrategy.generateClearText(MultiCodeCouponModel, int) method)

Specified by:

getCouponCodeNumberForClearText in interface CouponCodeClearTextGenerationStrategy

checkMaximumCouponCodesGenerated

protected void checkMaximumCouponCodesGenerated(MultiCodeCouponModel coupon,
                                                int length)

Checks if the given coupon's couponCodeNumber has exceeded the maximum number of coupon codes that can be generated for the given length.

 The maximum number of coupon codes are:
 length 2               2^8  = 256 coupons
 length 4               2^16 = 65.536 coupons
 length 6               2^24 = 16.777.216 coupons
 length 7               2^32 = 4.294.967.296 coupons
 

getBitshifts

protected int[] getBitshifts()

setBitshifts

public void setBitshifts(java.util.List<java.lang.Integer> bitshiftsList)

defines how many bits to shift for each two characters that are created from the seed (the MultiCodeCouponModel.couponCodeNumber) (default values are 0, 8, 16, 24, 32, 40, 48, 56)

getOffsets

protected int[] getOffsets()

setOffsets

public void setOffsets(java.util.List<java.lang.Integer> offsetsList)

defines the offset which is added when picking a character from the alphabet. (The default values are 3, 5, 7, 11, 13, 17, 19, 23, meaning that for the first two characters (i.e. one byte) the offset is 3.

checkLength

protected void checkLength(int length)

checks that the given length is supported by this strategy (only values 2,4,6,8 are valid)
