collectAllInstances

Full name: taxi.stdlib.collectAllInstances

​

Signature

declare extension function <T> collectAllInstances(collection: lang.taxi.Type<T>): T

​

Description

Collects and merges all instances of a type from the current data context, bypassing ambiguity checks.

Without this function, a search for T[] will return null when multiple separate collections of T exist (the result is considered ambiguous). collectAllInstances disables that check and concatenates all found instances into a single collection.

// Merge homeAddresses and workAddresses into one list
find { person: Person } as {
   allAddresses: collectAllInstances(Address)
}

​

Examples

Merges all Address collections on a Person into a single flat list, even though they live in separate fields.
