Features

• معالجة 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.
