Properties

dependenciesInfo

val dependenciesInfo: DependenciesValueInfo

Value information for each dependency of the computation. Mapping of keys as declared in the computation dependencies to their respective value information.

externalContexts

val externalContexts: ExternalContexts

val path: AbsolutePath

Path at which the computation is occurring.

val schemaPath: AbsolutePath

Path of the schema at which the computation is occurring.

Functions

fun <T> dependency(dependencyKey: String): T

Returns the value of the dependency with key dependencyKey.

fun <T> dependencyInfo(dependencyKey: String): ValueInfo<T>

Obtains the value information of the dependency with key dependencyKey.

dependencyInfoOrNull

fun <T> dependencyInfoOrNull(dependencyKey: String): ValueInfo<T>?

Obtains the value information of the dependency with key dependencyKey or null if the dependency could not be found in the form.

dependencyOrNull

fun <T> dependencyOrNull(dependencyKey: String): T?

Returns the value of the dependency with key dependencyKey or null if the dependency could not be found in the form.

fun dependencyPath(dependencyKey: String): AbsolutePath

Returns the path of the dependency with key dependencyKey.

dependencyPathOrNull

fun dependencyPathOrNull(dependencyKey: String): AbsolutePath?

Returns the path of the dependency with key dependencyKey or null if the dependency could not be found in the form.

dependencySchema

fun <T> dependencySchema(dependencyKey: String): Schema<T>

Returns the schema of the dependency with key dependencyKey.

dependencySchemaOrNull

fun <T> dependencySchemaOrNull(dependencyKey: String): Schema<T>?

Returns the schema of the dependency with key dependencyKey or null if the dependency could not be found in the form.

externalContext

fun <T> externalContext(externalContextName: String): T

Returns the external context with name externalContextName available to the computation.

externalContextOrNull

fun <T> externalContextOrNull(externalContextName: String): T?

Returns the external context with name externalContextName available to the computation or null if the external context could not be found.

fun <T> schema(): Schema<T>

Schema at which the computation is occurring.
