📝 WalkthroughWalkthroughRefactors public types to I-prefixed interfaces across core, parsers, codecs, and SQL visitor modules; classes now implement I* interfaces and public method signatures/return types switched from concrete classes to I* interfaces. Some filter helper utilities were removed and a new isFilters type-guard added. Changes

concrete Query class; change its method signature to accept the interface type
IQuery instead (i.e., update visitQuery to visitQuery(expr: IQuery): R) so
visitors depend on the abstraction not the concrete class, and update any

types and imports).

8-20: Align IFieldVisitor to the interface surface.IField is introduced, but IFieldVisitor still depends on the concrete Field type, which undercuts the interface-based decoupling goal. Consider switching the visitor to IField to keep the public surface fully interface-driven. This aligns with the parallel IFieldsVisitor pattern, which already uses IFields as its parameter type.
♻️ Suggested change

Critical bug: Array.isArray(input) always returns false for ICondition/IFilters objects.
The ICondition and IFilters interfaces are objects with operator and value properties—they are not arrays themselves. The check Array.isArray(input) will always fail, making this type guard non-functional.
To distinguish IFilters from a plain ICondition or IFilter, consider checking for the presence of IFilters-specific properties (like whether value is an array) or methods.
🐛 Proposed fix
export function isFilters(
input: ICondition,
operator?: string,
) : input is IFilters {
- if (!Array.isArray(input)) return false;
+ if (!Array.isArray(input.value)) return false;
if (operator) {
return operator === input.operator;
}
return true;
}Note: This fix assumes IFilters is the only condition type with an array value. If IFilter or other condition types can also have array values, additional discrimination logic may be needed (e.g., checking for 'accept' in input or a dedicated type discriminator property).

The clear() method in packages/core/src/parameter/filters/collection/module.ts has a critical bug in its loop condition.
The loop condition i === 0 should be i >= 0. The current code prevents the loop body from executing when the array has more than one element, making the method ineffective at clearing multi-element arrays.
Buggy code
clear() {
for (let i = this.value.length - 1; i === 0; i--) {
this.value.splice(i, 1);
}
}Change the condition to i >= 0 to properly iterate backward through all elements.
