I totally forgot about this bug here... Sorry. The source in the attached zip works, but is not the most up to date code. I will wrap together my current source within the next days and again attach it here as I lack commit access to the source repos. |

Ok, here it is. TJvMemoryDataset with filtering capabilities. Please diff the content of the attached zip file against the current stable version of JVCL as it was created using an ancient version (3.31.0.0). The Filtering should work out of the box and handle almost any kind of logical expression. The Code for the ExpressionParser (and evaluator) is based upon code by Vlad Skarzhevskyy released under GPL but Vlad Skarzhevskyy gave permission to re-release the code under MPL. See copyright notice in ExprParser.pas for more details. Currently there is onle one known issue: The equality check (foo='bar') is case insensitive due to usage of TMask class in unit Masks. The Expression parser supports the following operators: + addition - substraction / division * multiplication < less than > greater than & boolean "and" operator AND alias for & | boolean "or" operator OR alias for | ! boolean "not" It supports correct paranthesis matching. Therefore it should support almost any BDE compatible expression that it get's fed with. Hope you all like it Christian Schiffler |

Should not have been set to "resolved" by non developper account |

Warren is currently attempting a merge. THe source code provided in the zip is from a pretty old JVCL (pre delphi 2009 changes) so the merge is non-trivial. I am sure I can do it though. Will rename new contributed code unit from ExprParser.pas to JvExprParser.pas.. |
