Method Detail

escapeForRegex

public static String escapeForRegex(String raw)

Escape any regex special characters in the string. Note that the SPARQL parser requires two backslashes, in order to pass a single backslash to the REGEX function. Also escape a single quote ('), but only with a single backslash, since this one is for the SPARQL parser itself (single quote is not a special character to REGEX).

queryString - Query String

Query
