public boolean isDatabaseStructureCreated(String checkSQL)

Checks whether database tables are created.

Parameters:

checkSQL - SQL execute during check.

Returns:

true if checkSQL is success, else false.

Returns:

String

Throws:

Overloaded method with String input

Returns:

String

Throws:

checkStringBufferEndsWith

public static boolean checkStringBufferEndsWith(StringBuffer buffer,
                                                String suffix)

Checks that a string buffer ends up with a given string. It may sound trivial with the existing JDK API but the various implementation among JDKs can make those methods extremely resource intensive and perform poorly due to massive memory allocation and copying. See

Parameters:

buffer - the buffer to perform the check on

suffix - the suffix

Returns:

true if the character sequence represented by the argument is a suffix of the character sequence represented by the StringBuffer object; false otherwise. Note that the result will be true if the argument is the empty string.
