The system employs convention-based member matching, flattening-based property projection, and recursive ty

AutoMapper is a strongly typed object-to-object mapper for .NET. It provides utilities for copying data between different object representations using convention-based property matching to eliminate manual assignment code. The library automates the transformation of data models by matching source and destination properties based on shared names and types. It supports the conversion of internal domain models into data transfer objects, facilitating data movement between presentation, business, and data access layers. The system employs reflection-based type discovery and recursive object grap

MJExtension is a JSON serialization library and model mapping framework used to convert data between JSON strings and structured model objects. It functions as an object data mapper that handles the encoding and decoding of complex object hierarchies for network transmission and storage.

This approach allows for data transformation without requiring base class inheritance, decorators, or extensions to the underlying model classes. The system supports recurs

Mapper is a MyBatis-specific library that provides annotation-driven object-relational mapping, enabling single-table CRUD operations without writing SQL or XML. It uses Java reflection and field-level annotations to map entity fields to database columns, configure primary key generation strategies, and generate mapper interfaces and model classes from database schemas. The library distinguishes itself through several practical capabilities. It includes a safe operation guard that blocks delete and update calls lacking query conditions, preventing accidental full-table modifications. Its exam

This library is a YAML encoder and decoder for native Go data structures. It provides the tools necessary to transform internal data into YAML formatted text and convert YAML input streams back into structured data. The parser includes built-in protections against resource exhaustion attacks by enforcing limits on document depth and alias resolution. It also ensures deterministic output by employing consistent key sorting for maps. The project covers serialization and deserialization workflows, including struct mapping and custom marshaling interfaces. It also handles input encoding detectio

Goja is a JavaScript engine and ECMAScript compliant interpreter implemented entirely in Go. It serves as an embedded scripting engine that allows Go applications to execute JavaScript code and integrate a programmable scripting layer without relying on Cgo or external native dependencies. The project functions as a bridge between Go and JavaScript, enabling bidirectional data exchange and function invocation. It allows Go hosts to expose native structs, slices, and maps as JavaScript objects and arrays, while providing mechanisms to export script values and functions back into native Go type

js-yaml is a JavaScript library providing a programmatic interface for parsing and dumping YAML data. It functions as a parser and serializer that converts YAML strings into JavaScript objects and transforms JavaScript objects back into YAML format. The library includes a command-line interface for parsing or dumping YAML data via direct input or data pipes. It also features an abstract syntax tree transformer to modify the structure of data during serialization. The project provides capabilities for multi-document processing and the definition of custom schemas and tags to handle specialize

NPOI is a pure .NET library for reading and writing Microsoft Office files in both legacy binary (.xls) and modern OpenXML (.xlsx, .docx) formats, operating entirely without requiring Microsoft Office or COM interop. It runs on Windows and Linux under .NET Standard and .NET Framework runtimes, using only managed code to parse and generate Office documents. The library provides comprehensive spreadsheet capabilities, including creating, editing, and reading Excel workbooks in both .xls and .xlsx formats, with support for cell formatting, styles, and formulas. It includes a streaming row-by-row

Mapster ist ein .NET-Objekt-zu-Objekt-Mapper und eine hochperformante Mapping-Engine zur Transformation von Daten zwischen verschiedenen Objektmodellen. Sie fungiert als typsicheres Datentransfer-Tool und LINQ-Abfrageprojektionstool, um Daten zwischen interner Logik und externen Datenstrukturen zu bewegen. Die Engine nutzt kompilierte Mapping-Ausdrücke und Maschinencode, um den Overhead während der Objektkonvertierung zu reduzieren. Sie ermöglicht insbesondere die Projektion abfragbarer Datenquellen direkt in Zieltypen, um den Datenbankabruf zu optimieren. Das Toolset deckt die Generierung von Data Transfer Objects, die Transformation unveränderlicher Daten und die Projektion von Abfrageergebnissen ab. Es enthält Funktionen für das Mapping unveränderlicher Sammlungen, die Wahrung von Objektreferenzen und das Injizieren von Laufzeitparametern in den Transformationsprozess.

Rhino ist eine Java-basierte JavaScript-Engine, die eine ECMAScript-Kompatibilitätsschicht für die Ausführung innerhalb einer Java Virtual Machine implementiert.
