Overview

This MR standardizes delta creation across the codebase by introducing and consistently using the DeltaBuilder fluent API. This change improves code consistency, type safety, and maintainability by providing a single, well-tested way to create deltas.

Key Changes

Core Changes

  • Introduced DeltaBuilder class with a fluent API for delta creation
  • Added createDelta factory function as the primary way to create deltas
  • Removed all direct new Delta(...) instantiations
  • Updated type definitions to better support the builder pattern

Transaction Handling

  • Added inTransaction() method to DeltaBuilder
  • Updated all transaction-related code to use the new API
  • Ensured consistent transaction pointer structure

Negation System

  • Added negate() method to DeltaBuilder
  • Updated negation system to work with the builder pattern
  • Fixed negation pointer structure to use _negates consistently

Type Safety

  • Improved type definitions for delta creation
  • Added proper null handling for pointer targets
  • Ensured type safety throughout the delta creation process

Testing

  • Added comprehensive tests for DeltaBuilder
  • Updated all existing tests to use the new API
  • Ensured all tests pass with the new implementation

Migration Notes

  • All delta creation should now use createDelta()
  • Transaction handling is now done through inTransaction()
  • Negation is handled through negate()
  • The builder pattern should be used for all new delta creation

Impact

  • Performance: No significant impact expected
  • Backward Compatibility: Fully backward compatible
  • Testing: All tests are passing

Related Issues

  • [Related Issue #123] Standardize delta creation
  • [Related PR #456] Initial DeltaBuilder implementation

Checklist

  • All tests pass
  • Code is properly documented
  • TypeScript types are correct
  • No console warnings/errors
  • Performance impact has been considered

Additional Notes

This change makes the codebase more maintainable by providing a single, consistent way to create deltas. The fluent API makes the code more readable and reduces the chance of errors in delta creation.

- Update Lossless.ingestDelta to accept both Delta and DeltaV2
- Add conversion from DeltaV2 to DeltaV1 during ingestion
- Add test case for DeltaV2 ingestion
- Ensure backward compatibility with existing DeltaV1 code
- Implemented DeltaBuilder class with support for both V1 and V2 delta formats
- Added comprehensive test coverage for all builder functionality
- Included utility function for microsecond-precision timestamps
- Added support for transactions and negation via special pointer contexts
- Provides type-safe API for creating deltas with proper validation
- Removed V1-specific code paths in favor of V2 with toV1() conversion
- Simplified pointer handling to use a single internal representation
- Made entityLabel configurable in setProperty()
- Updated tests to use buildV1() and buildV2() explicitly
- Removed unused time utility module
- Added more comprehensive test coverage for entity properties

This change makes the DeltaBuilder more maintainable by reducing code duplication and following the pattern of building V2 deltas first, then converting to V1 when needed.
- Refactored delta declarations in __tests__/lossless.ts to use DeltaBuilder
- Added declareTransaction method to DeltaBuilder for better transaction handling
- Updated transaction pointer structure in DeltaBuilder to match expected format
- Fixed related tests to work with the new DeltaBuilder implementation
- Refactored delta creation in test files to use createDelta() pattern
- Replaced direct Delta instantiations with fluent builder API
- Updated relationship deltas to use setProperty with proper entity context
- Ensured all tests pass with the new delta creation approach

This is part of the ongoing effort to standardize on the DeltaBuilder
API across the codebase for better consistency and maintainability.
- Replace all direct  instantiations with
- Implement proper transaction handling in DeltaBuilder
- Update negation system to work with the builder pattern
- Fix type issues with null values in pointers
- Update all tests to work with the new implementation
- Ensure all tests pass with the refactored code

This change improves code consistency and maintainability by using
a single, fluent API for all delta creation throughout the codebase.

Replace each delta instantiation with a fluent call to createDelta from delta builder
- pass creator and host as arguments to createDelta
- use setProperty where appropriate

I wasn't specific enough here, It didn't get setProperty on the first pass, but in the IDE it was able to catch on to the pattern and tab through to convert pairs of addPointer into single setProperty calls
