Extractor Factory

The ExtractorFactory is responsible for creating and managing extractor instances based on entity types.

Overview

The ExtractorFactory serves as the central point for:

• Determining which extractor class to use for a given entity type
• Creating properly configured extractor instances
• Providing information about supported entity types

Key features:

• Uses metadata configuration to map entity types to extractor classes
• Leverages EspoCRM's dependency injection system
• Provides validation before extractor creation

Typical usage scenarios:

• Checking if an entity type has an associated extractor
• Retrieving all supported entity types
• Creating a configured extractor instance

• Dependencies:
• Metadata
• InjectableFactory
• Key Methods:
• isExtractor(string|Entity $entityTypeOrEntity): bool
• Checks if an extractor exists for the given entity
• getClassName(string|Entity $entityTypeOrEntity): ?string
• Returns the extractor class name for an entity type
• getExtractTargetEntityTypes(): array
• Returns all entity types with extractors

Metadata Configuration

The factory reads extractor mappings from:

['app', 'aiParsing', 'extractorClassNameMap']

Where keys are entity types and values are corresponding extractor class names.
