Validation

MetaWeaver validates values against parameter specifications defined in UMetaWeaverMetadataDefinitionSet.

Parameter Types

• Bool, Int, Float, String
• Enum (string list)
  • Values are trimmed, non‑empty, and unique per enum.
  • An enum can be marked Exclusive; when enabled, only listed values are valid.
• Asset Reference
  • Can restrict to an allowed base class.

Default Value Canonicalization

• Default values are canonicalized (trimmed/normalized) to ensure consistent comparison.

Validation Flow

1. Definitions describe required keys and constraints.
2. Editors enforce constraints inline and surface errors on commit.
3. UMetaWeaverValidationSubsystem exposes ValidateAsset() for programmatic checks.

Error Reporting

• Missing required keys
• Invalid format/type
• Exclusive enum value not in list
• Asset reference not assignable to allowed class
