exactly matches detects samples that exactly match (ignoring case) a Regular Expression.
For example, given the following case fragment,
ABC abcd12 12345 DEF AB12345678
ABC exactly matches “[0-9]{5}”
some ABC exactly matches “[a-m]{4}[0-2]{2}”
DEF exactly matches “[a-z]{2,3}[0-9]{8}”
exactly matches is a stronger condition than matches as the complete sample value must match the regular expression. Whereas a condition using matches need only match part of the sample value. To illustrate this difference, consider the two further examples:
ABC matches “[0-9]{3}”
not ABC exactly matches “[0-9]{3}”
