Properties

dependencies

open override val dependencies: Map<String, DependencyInfo>

Dependencies of the validation. Mapping of keys to the paths this validation depends on. Keys can be used within a ValidationContext to access the value of the dependencies.

dependsOnDescendants

Whether the form manager should reevaluate this validation whenever a descendant of the value being validated changes. This is false by default.

externalContextDependencies

open override val externalContextDependencies: Set<String>

Set of external context dependencies of the validation.

Functions

toString

open override fun toString(): String

validate

override fun ValidationContext.validate(): Flow<ValidationIssue>

Runs the validation within a ValidationContext containing the value being validated and the value of all declared dependencies. Returns a flow over all found issues.

abstract fun validate(context: ValidationContext, issues: MutableList<ValidationIssue>): CompletionStage<Unit>?

Asynchronous implementation of ValidationContext.validate returning a completion stage. Validation issues should be added to issues (which is a synchronized list).
