convertLikeLocation

static String convertLikeLocation(String location)

Does some special character escaping for LIKE query.

The following rules should take place in the future (for now, only a subset is implemented correctly):

• * -> * (No special meaning in SQL, even numbers of are ignored.)

• • -> %% (Wildcard, to be converted to a more complicated regex without / later. Exception: at the beginning of a search expression, convert to %.)

• ** -> % (Wildcard, also *, **, … -> %)

• _ -> _ (Prevent special meaning in SQL)

• % -> % (Prevent special meaning in SQL)

• Heading / is removed

Parameters:

• String – location The String to be converted.

Returns:

The converted String.

getCacheKey

public String getCacheKey()

requiresPatternMatching

static boolean requiresPatternMatching(String location)

Tests if the location String is intended for pattern matching.

Parameters:

Returns:

True if the location requires pattern matching for a LIKE query, false otherwise.

toElement

public Element toElement()

toString

public String toString()

For testing purposes, create a string representing the corresponding query.

Returns:

The String “SAT()”, where “” is the query string.
