isPlainType

public static boolean isPlainType(Class<?> cls)

Parameters:

cls - Class.

Returns:

true is the type is plain (not user's custom class).

exceptionToSqlErrorCode

public static int exceptionToSqlErrorCode(Throwable e)

Parameters:

e - Exception to convert.

Returns:

IgniteQueryErrorCode.

translateSqlWildcardsToRegex

public static String translateSqlWildcardsToRegex(String sqlPtrn)

Converts sql pattern wildcards into java regex wildcards.

Translates "_" to "." and "%" to ".*" if those are not escaped with "\" ("\_" or "\%").

All other characters are considered normal and will be escaped if necessary.

 Example:
      som_    -->     som.
      so%     -->     so.*
      s[om]e  -->     so\[om\]e
      so\_me  -->     so_me
      some?   -->     some\?
      som\e   -->     som\\e
