java.lang.Object

io.flamingock.internal.common.core.template.TemplateValidator

public class TemplateValidator
extends java.lang.Object

Validates that template-based YAML changes have the correct structure for their template type.

This validator ensures:

• SimpleTemplate: Must have apply, may have rollback, must NOT have steps
• SteppableTemplate: Must have steps, must NOT have apply or rollback at root level

The validator is stateless and used at runtime during pipeline building to catch structural mismatches before any change execution begins.
