+// | Special note concerning code documentation: |

+// | Fusebox uses an XML style of documentation called Fusedoc. (Which |
+// | is admittedly not well suited to documenting classes and functions. |
+// | This short-coming is being addressed by the Fusebox community.) PEAR |
+// | uses a Javadoc style of documentation called PHPDoc. (www.phpdoc.de) |
+// | Since this class extension spans two groups of users, it is asked |
+// | that the members of each respect the documentation standard of the |
+// | other. So it is a further requirement that both documentation |
+// | standards be included and maintained. If assistance is required |
+// | please contact Alan Richmond. |

+ need for a separate .sim file.
+ </history>
+ <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Create" date="10-July-2002">
+ Rewrote in PHP as an extention to the PEAR DB API.
+ Functions supported:
+ connect, disconnect, query, fetchRow, freeResult,
+ numCols, numRows, getSpecialQuery
+ David Huyck (bombusbee.com) added ability to escape special
+ characters (i.e., delimiters) using a '\'.
+ Extended PEAR DB options[] for adding incoming parameters. Added
+ options: columnDelim, dataDelim, eolDelim
+ </history>
+ <history author="David Huyck" email="b@bombusbee.com" type="Update" date="19-July-2002">
+ Added the ability to set the QuerySim options at runtime.
+ Default options are:
+ 'columnDelim' => ',', // Commas split the column names
+ 'dataDelim' => '|', // Pipes split the data fields
+ 'eolDelim' => chr(13).chr(10) // Carriage returns split the
+ // lines of data
+ Affected functions are:
+ DB_querysim(): set the default options when the
+ constructor method is called
+ _parseQuerySim($query): altered the parsing of lines, column
+ names, and data fields
+ _empty2null: altered the way this function is called
+ to simplify calling it
+ </history>
+ <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="24-July-2002">
+ Added error catching for malformed QuerySim text.
+ Bug fix _empty2null(): altered version was returning unmodified
+ lineData.
+ Cleanup:
+ PEAR compliant formatting, finished PHPDocs and added 'out' to
+ Fusedoc 'io'.
+ Broke up _parseQuerySim() into _buildResult() and _parseOnDelim()
+ to containerize duplicate parse code.
+ </history>
+ <history author="David Huyck" email="b@bombusbee.com" type="Update" date="25-July-2002">
+ Edited the _buildResult() and _parseOnDelim() functions to improve
+ reliability of special character escaping.
+ Re-introduced a custom setOption() method to throw an error when a
+ person tries to set one of the delimiters to '\'.
+ </history>
+ <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="27-July-2002">
+ Added '/' delimiter param to preg_quote() in _empty2null() and
+ _parseOnDelim() so '/' can be used as a delimiter.
+ Added error check for columnDelim == eolDelim or dataDelim == eolDelim.
+ Renamed some variables for consistancy.
+ </history>
+ <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="30-July-2002">
+ Removed protected function _empty2null(). Turns out preg_split()
+ deals with empty elemants by making them zero length strings, just
+ what they ended up being anyway. This should speed things up a little.
+ Affected functions:
+ _parseOnDelim() perform trim on line here, instead of in
+ _empty2null().
+ _buildResult() remove call to _empty2null().
+ _empty2null() removed function.
+ </history>
+ <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="1-Jan-2003">
+ Ported to PEAR MDB2.
+ Methods supported:
+ connect, query, getColumnNames, numCols, valid, fetch,
+ numRows, free, fetchRow, nextResult, setLimit
+ (inherited).
+ </history>
+ <history
+ Removed array_change_key_case() work around for <4.2.0 in
+ getColumnNames(), found it already done in MDB2/Common.php.
+ </history>
+ <history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="3-Feb-2003">
+ Changed default eolDelim to a *nix file eol, since we're trimming
+ the result anyway, it makes no difference for Windows. Now only
+ Mac file eols should need to be set (and other kinds of chars).
+ </history>
+ <note author="Alan Richmond">
+ Got WAY too long. See querysim_readme.txt for instructions and some
+ examples.
+ io section only documents elements of DB_result that DB_querysim uses,
+ adds or changes; see MDB2 and MDB2_Driver_Common for more info.

+ * handled as a primary key or at least as part of the compound
+ * unique index of the table that will determine the row that will
+ * updated if it exists or inserted a new row otherwise.
