Predicates
| getAParseMode | Gets a parse mode that is set at this evaluation (in at least one path from the creation of the regular expression object). |
| getARegex | Gets a regular expression value that is evaluated here (if any can be identified). |
| getAnOptionsInput | Gets a dataflow node for an options input that might contain options such as parse mode flags (if any). |
| getRegexInputNode | Gets the input to this call that is the regular expression being evaluated. This may be a regular expression object or a string literal. |
| getStringInputNode | Gets the input to this call that is the string the regular expression is evaluated on. |
| isUsedAsReplace | Holds if this regular expression evaluation is a ‘replacement’ operation, such as replacing all matches of the regular expression in the input string with another string. |
