Rowcast Laravel Package

Added

• QueryBuilder\Expression\Expression — embed SQL expressions in UPDATE set() and INSERT values(). Use Expression::raw('balance - :amount') for arithmetic, function calls, or column references.
• Tests for Expression support in V2QueryBuilderTest.

Added

• ConnectionInterface — abstract contract for database connections, enabling custom implementations and easier testing.
• Connection::getDriverName() — returns the PDO driver name without accessing PDO directly.
• Persistence\ValueConverterInterface — extensible contract for converting PHP values to DB format (the write-side counterpart of TypeCasterInterface).
• Persistence\ValueConverterRegistry — chain-of-responsibility registry for value converters.
• Persistence\BoolValueConverter — converts bool to int (0/1).
• Persistence\EnumValueConverter — converts BackedEnum to its backing value.
• Persistence\DateTimeValueConverter — converts DateTimeInterface to a formatted string (customizable format).
• Persistence\DtoExtractor — extracts column/value pairs from DTO objects via Reflection.
• QueryBuilder\Compiler\SqlCompilerInterface — contract for SQL generation strategies.
• QueryBuilder\Compiler\SelectCompiler — generates SELECT SQL.
• QueryBuilder\Compiler\InsertCompiler — generates INSERT SQL.
• QueryBuilder\Compiler\UpdateCompiler — generates UPDATE SQL.
• QueryBuilder\Compiler\DeleteCompiler — generates DELETE SQL.

Changed

• DataMapper now depends on ConnectionInterface instead of the concrete Connection class.
• DataMapper now delegates DTO extraction to DtoExtractor and value conversion to ValueConverterInterface.
• DataMapper constructor accepts optional DtoExtractor and ValueConverterInterface parameters.
• QueryBuilder now depends on ConnectionInterface instead of the concrete Connection class.
• QueryBuilder::getSQL() delegates to dedicated compiler classes instead of private methods.

Removed

• DataMapper::extractData() — replaced by Persistence\DtoExtractor::extract().
• DataMapper::convertValueForDb() — replaced by Persistence\ValueConverterRegistry.
• QueryBuilder::getSelectSQL(), getInsertSQL(), getUpdateSQL(), getDeleteSQL() — replaced by compiler classes.
