Signature

IPolicyRegistry.sol

function compositePolicyChildIds(uint64 policyId) external view returns (uint64[] memory);

Field	Value
Selector	`0x7c40df74`
Canonical signature	`compositePolicyChildIds(uint64)`

Returns the ordered child-policy ID set of the composite identified by policyId.

Child policies are returned in the order they were last written; the registry preserves caller ordering verbatim without sorting or de-duplicating.
Returns an empty array for simple policies, built-in sentinels (ALWAYS_ALLOW, ALWAYS_BLOCK), unknown IDs, and malformed IDs.
Never reverts.
An empty return unambiguously means “not a composite”.

Name	Type	Description
`policyId`	`uint64`	The composite policy to query.

Type	Description
`uint64[] memory`	Child policy IDs, or an empty array if `policyId` is not a composite.

Read-only. Always callable regardless of whether the PolicyRegistry feature is active.

Usage Example

uint64[] memory children = IPolicyRegistry(registry).compositePolicyChildIds(policyId);
