6You are in 'detached HEAD' state. You can look around, make experimental

7changes and commit them, and you can discard any commits you make in this

8state without impacting any branches by switching back to a branch.

10If you want to create a new branch to retain commits you create, you may

11do so (now or later) by using -c with the switch command. Example:

13 git switch -c <new-branch-name>

15Or undo this operation with:

17 git switch -

19Turn off this advice by setting config variable advice.detachedHead to false

330[info] BindingExample:

331[info] com.thoughtworks.binding

332[info] Binding

333[info] Var

334[info] + Source variable of data binding expression.

335[info] + You can manually change the value:

336[info] + Then, any data binding expressions that depend on this [[Var]] will be changed automatically.

337[info] Rx

338[info] Observable

339[info] + A [[Binding]] that can be terminated.

340[info] + Once the value turned into a [[scala.None]], this [[Observable]] would be considered as terminated, and any

341[info] future changes of this [[Observable]] will be ignored by any [[Rx]] operators derived from this [[Observable]],

342[info] even if this [[Observable]] turns into a [[scala.Some]] value again.

343[info] - @note

344[info] Even though an [[Observable]] is technically a [[Binding]], an [[Observable]] created from a [[Rx]] operator

345[info] does not actually indicates data-binding.

346[info] + For example, given an [[Observable]] created from [[Rx.concat]],

347[info] + when a source value gets changed,

348[info] + and the source value is changed back to the original value,

349[info] + then the value of the derived observable might not be the original value.

350[info] + In contrast, if the `concat` operator is implemented by ordinary [[Binding.bind]] macros, the derived Binding is

351[info] indeed a data-binding, i.e. it always perform the same calculation for the same values of source [[Binding]]s.

352[info] concat

353[info] + Emit the emissions from two or more [[Observable]]s without interleaving them.

354[info] - @example

355[info] Given a sequence of [[Observable]]s,

356[info] + when concatenate them together,

357[info] + the concatenated value should be the first [[scala.Some]] value in the sequence of observables;

358[info] + when the current observable becomes `None`,

359[info] + the concatenated value should be the next [[scala.Some]] value in the sequence of observables,

360[info] + even when the next [[scala.Some]] value is derived from another [[Binding]];

361[info] + when the value of the upstream [[Binding]] is changed to another [[scala.Some]] value,

362[info] + the concatenated value should be changed accordingly;

363[info] + when multiple observables become [[scala.None]] at once,

364[info] + they all should be skipped when calculate the concatenated value;

365[info] + when the last observable in the sequence becomes [[scala.None]],

366[info] + the concatenated value should become [[scala.None]] permanently,

367[info] + even when some observables in the sequence become [[scala.Some]] again.

368[info] defer

369[info] + do not create the Observable until the observer subscribes

370[info] - @example

371[info] Circular referenced [[Observable]]s can be created with the help of [[defer]]

372[info] + Initially, `observable1` did not subscribe `observable2` because `source` is `init`,

373[info] + therefore observable2 should be `None`,

374[info] + when `source` changed,

375[info] + `observable1` should subscribe `observable2`, and there should be `Some` values.

376[info] + Even though circular referenced [[Observable]]s can be created in this way, their calculation must not be

377[info] mutually dependent.

378[info] merge

379[info] + Combine multiple [[Observable]]s into one by merging their emissions.

380[info] - @example

381[info] Given a sequence of [[Observable]]s,

382[info] + when merge them together,

383[info] + the merged value should be the first [[scala.Some]] value in the sequence of observables;

384[info] + when the some but not all of the observable becomes `None`,

385[info] + the merged value should be unchanged,

386[info] + when any of the observable becomes `Some` value,

387[info] + the merged value should be the new value,

388[info] + even when a previous `None` observable becomes `Some` value,,

389[info] + the merged value should be the new value of the previous `None` observable,

390[info] + when multiple observables are changed at once,

391[info] + the merged value should be the value of the last derived observable

392[info] + when all the observables become `None`,

393[info] toBindingSeq

394[info] + convert an Observable into a [[BindingSeq]].

395[info] - @example

396[info] Given a source observable,

397[info] + when converting it into a [[BindingSeq]],

398[info] + and flat-mapping to the result,

399[info] + then result should have the values corresponding to the source observable,

400[info] + when the source observable changes,

401[info] + then the corresponding new value should be appended to the result,

402[info] + when the source observable terminates,

403[info] + then the result should be empty

404[info] Binding

405[info] + A data binding expression that represents a value that automatically recalculates when its dependencies change.

406[info] - @example

407[info] You may create a data binding expression via `Binding { ??? }` block annotation.

408[info] + A data binding expression may depend on other binding expressions via [[bind]] method:
