Json Schema Validator
Această bibliotecă este un instrument bazat pe Java pentru impunerea constrângerilor structurilor de date și verificarea formatelor tehnice în raport cu specificațiile de schemă definite. Funcționează ca un utilitar de procesare care parsează structuri de date complexe în timp ce gestionează referințele externe de schemă și dependențele circulare.
Motorul se distinge printr-un design de procesor imuabil care permite validarea concurentă, thread-safe, fără a necesita sincronizare externă. Utilizează aritmetica cu precizie arbitrară pentru a evalua constrângerile numerice, prevenind erorile comune de rotunjire în virgulă mobilă, și utilizează procesarea la nivel de caracter pentru a asigura validarea string-urilor conștientă de Unicode pentru simboluri complexe. Dezvoltatorii pot extinde pipeline-ul de bază prin înregistrarea de cuvinte cheie personalizate și handler-e de format pentru a implementa logica de business specializată.
Proiectul oferă o gestionare cuprinzătoare a schemelor, inclusiv verificarea conformității structurale în raport cu meta-schemele, rezoluția dependențelor bazată pe URI și încărcarea configurabilă a schemelor. Suportă raportarea detaliată a erorilor care continuă validarea pe elementele copil chiar și după eșecurile părinților și include o interfață de linie de comandă pentru verificarea datelor din terminal.
Features
- Procesare JSON - Provides a robust engine for parsing, transforming, and validating complex data structures against defined schema specifications.
- JSON Schema Validation - Validates JSON data against schema specifications with support for version switching and high-precision numeric values.
- Java Validation Libraries - Provides a Java-based tool for enforcing data structure constraints and technical formats using standard schema definitions.
- Schema Reference Resolution - Fetches and processes external schema definitions using various URI schemes while managing custom handlers and detecting circular dependencies.
- Immutable Processors - Performs validation using immutable processors that allow a single instance to be shared safely across multiple concurrent application threads.
- Date and Time Libraries - Verifies date and time strings against international standards with support for variable precision and time zones.
- Numeric Precision Constraints - Enforces numeric precision constraints using arbitrary-precision arithmetic to avoid floating-point inaccuracies.
- Networked Schema Resolvers - Resolves and loads external schema definitions across network protocols while managing URI namespaces.
- High Precision Mathematics - Verifies numeric and string data against strict constraints to prevent rounding errors and encoding issues.
- Unicode Length Validations - Evaluates string constraints using character-level processing to correctly handle complex Unicode symbols.
- Custom Validation Rules - Supports custom validation rules by allowing registration of unique keywords and format attributes.
- Schema Keyword Functions - Allows developers to inject custom logic by registering new keywords and format handlers into the validation pipeline.
- Domain-Specific Validation Rules - Enforces specialized business rules by extending standard validation logic with custom keywords and formats.
- URI Namespace Redirectors - Controls how schemas are retrieved by preloading files, redirecting URI namespaces, and registering custom downloaders for various network protocols.
- Validation Error Reporters - Supports detailed error reporting that continues validation across child elements even after parent failures to ensure comprehensive compliance tracking.
- Arbitrary-Precision Arithmetic - Uses arbitrary-precision arithmetic to evaluate numeric constraints and prevent floating-point rounding errors.
- Constraint-Based JSON Validators - Provides a standalone command-line interface for validating JSON documents against schema requirements.
- Multi-Threaded Batch Processing - Executes thread-safe validation tasks concurrently to maintain high performance during heavy data processing.
- Recursive Schema Resolvers - Resolves external schema dependencies via URI and detects circular references to prevent infinite processing loops.
- Regular Expression Validations - Applies regular expressions to ensure uniform string validation across different computing environments.
- Meta-Schema Validations - Verifies that schema definitions are structurally correct and fully compliant with the requirements of the core meta-schema.
- Immutable State Patterns - Encapsulates validation logic in immutable, thread-safe objects to enable concurrent execution without external synchronization.
- String Format Validators - Validates string values against technical standards including base64, cryptographic hashes, and URI templates.
