Data scratch - file reference

[jan-goral]

Plan

According to the specification described in epic #1727
add abstraction and implementation for the following part of the data layer:

Abstraction

ftl/data/FileReference.kt

package ftl.data

val downloadFileReference: FileReference.Download get() = TODO()
val uploadFileReference: FileReference.Download get() = TODO()
val existFileReference: FileReference.Exist get() = TODO()

data class FileReference(
    val local: String = "",
    val remote: String = ""
) {
    interface Download : (FileReference) -> FileReference
    interface Upload : (FileReference) -> FileReference
    interface Exist : (FileReference) -> Boolean
}

Target

• FileReference.kt

Adapter

ftl/adapter/GoogleFileReference.kt

Note

Consider reuse or expand RemoteStorage implementation.
