Methods#

apply#

public void apply(QueryInterface query)#

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:

  • String – location The String to be converted.

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.
