class AbstractReferenceCollection

abstract class AbstractReferenceCollection<K, V extends Disposable>
    implements Disposable {}

Abstract class for a map of reference-counted disposable objects, with the following features:
- values are not inserted explicitly; instead, acquire() is used to create the value for a given key, or return the previously created value for it. How the value is created for a given key is implementation specific.
- any subsquent acquire() with the same key will bump the reference count on that value. acquire() returns not the value directly but a reference object that holds the value. Calling dispose() on the reference decreases the value's effective reference count.
- a contained value will have its dispose() function called when its reference count reaches zero. The key/value pair will be purged from the collection.
- calling dispose() on the value directly, instead of calling it on the reference returned by acquire(), will automatically dispose all outstanding references to that value and the key/value pair will be purged from the collection.
- supports synchronous and asynchronous implementations. acquire() will return a Promise if the value cannot be created immediately
- functions has|keys|values|get are always synchronous and the result excludes asynchronous additions in flight.
- functions values|get return the value directly and not a reference to the value. Use these functions to obtain a value without bumping its reference count.
- clients can register to be notified when values are added and removed; notification for asynchronous additions happen when the creation completes, not when it's requested.
- keys can be any value/object that can be successfully stringified using JSON.stringify(), sans arguments
- calling dispose() on the collection will dispose all outstanding references to all contained values, which results in the disposal of the values themselves.

class DisposableCollection

class DisposableCollection implements Disposable {}

Utility for tracking a collection of Disposable objects.
This utility provides a number of benefits over just using an array of Disposables:
- the collection is auto-pruned when an element it contains is disposed by any code that has a reference to it - you can register to be notified when all elements in the collection have been disposed [1] - you can conveniently dispose all elements by calling dispose() on the collection
Unlike an array, however, this utility does not give you direct access to its elements.
Being notified when all elements are disposed is simple:
const dc = new DisposableCollection(myDisposables); dc.onDispose(() => { console.log('All elements in the collection have been disposed'); });
[1] The collection will notify only once. It will continue to function in so far as accepting new Disposables and pruning them when they are disposed, but such activity will never result in another notification.

Establish a RPC protocol on top of a given channel. By default the rpc protocol is bi-directional, meaning it is possible to send requests and notifications to the remote side (i.e. acts as client) as well as receiving requests and notifications from the remote side (i.e. acts as a server). Clients can get a promise for a remote request result that will be either resolved or rejected depending on the success of the request. Keeps track of outstanding requests and matches replies to the appropriate request Currently, there is no timeout handling for long running requests implemented. The bi-directional mode can be reconfigured using the RpcProtocolOptions to construct an RPC protocol instance that acts only as client or server instead.

class RpcProxyFactory

class RpcProxyFactory<T extends object> implements ProxyHandler<T> {}

Factory for RPC proxy objects.
A RPC proxy exposes the programmatic interface of an object through Theia's RPC protocol. This allows remote programs to call methods of this objects by sending RPC requests. This takes place over a bi-directional stream, where both ends can expose an object and both can call methods on each other' exposed object.
For example, assuming we have an object of the following type on one end:
class Foo { bar(baz: number): number { return baz + 1 } }
which we want to expose through a RPC interface. We would do:
let target = new Foo() let factory = new RpcProxyFactory('/foo', target) factory.onConnection(connection)
The party at the other end of the connection, in order to remotely call methods on this object would do:
let factory = new RpcProxyFactory('/foo') factory.onConnection(connection) let proxy = factory.createProxy(); let result = proxy.bar(42) // result is equal to 43
One the wire, it would look like this:
--> { "type":"1", "id": 1, "method": "bar", "args": [42]} <-- { "type":"3", "id": 1, "res": 43}
Note that in the code of the caller, we didn't pass a target object to RpcProxyFactory, because we don't want/need to expose an object. If we had passed a target object, the other side could've called methods on it.
Parameter
- The type of the object to expose to RPC.

constructor

constructor(target?: any, rpcProtocolFactory?: RpcProtocolFactory);

Build a new RpcProxyFactory.
Parameter target
The object to expose to RPC methods calls. If this is omitted, the proxy won't be able to handle requests, only send them.

property rpcDeferred

property rpcProtocolFactory

property target

method createProxy

createProxy: () => RpcProxy<T>;

Create a Proxy exposing the interface of an object of type T. This Proxy can be used to do RPC method calls on the remote target object as if it was local.
If T implements RpcServer then a client is used as a target object for a remote target object.

method deserializeError

protected deserializeError: (capturedError: Error, e: any) => any;

method get

get: (target: T, p: PropertyKey, receiver: any) => any;

Get a callable object that executes a RPC method call.
Getting a property on the Proxy object returns a callable that, when called, executes a RPC call. The name of the property defines the method to be called. The callable takes a variable number of arguments, which are passed in the RPC method call.
For example, if you have a Proxy object:
let fooProxyFactory = RpcProxyFactory('/foo') let fooProxy = fooProxyFactory.createProxy()
accessing fooProxy.bar will return a callable that, when called, executes a RPC method call to method bar. Therefore, doing fooProxy.bar() will call the bar method on the remote Foo object.
Parameter target
unused.
Parameter p
The property accessed on the Proxy object.
Parameter receiver
unused.
Returns
A callable that executes the RPC call.

method isNotification

protected isNotification: (p: PropertyKey) => boolean;

Return whether the given property represents a notification.
A property leads to a notification rather than a method call if its name begins with notify or on.
Parameter p
The property being called on the proxy. Whether p represents a notification.

method listen

listen: (channel: Channel) => void;

Connect a Channel to the factory by creating an RpcProtocol on top of it.
This protocol will be used to send/receive RPC requests and responses.

method onNotification

protected onNotification: (method: string, ...args: any[]) => void;

Process an incoming RPC notification.
Same as [[onRequest]], but called on incoming notifications rather than methods calls.

method onRequest

protected onRequest: (method: string, ...args: any[]) => Promise<any>;

Process an incoming RPC method call.
onRequest is called when the RPC connection received a method call request. It calls the corresponding method on [[target]].
The return value is a Promise object that is resolved with the return value of the method call, if it is successful. The promise is rejected if the called method does not exist or if it throws.
Returns
A promise of the method call completion.

protected serializeError: (e: any) => any;

function binarySearch2

binarySearch2: (

Performs a binary search algorithm over a sorted collection. Useful for cases when we need to perform a binary search over something that isn't actually an array, and converting data to an array would defeat the use of binary search in the first place.
Parameter length
The collection length.
Parameter compareToKey
A function that takes an index of an element in the collection and returns zero if the value at this index is equal to the search key, a negative number if the value precedes the search key in the sorting order, or a positive number if the search key precedes the value. A non-negative index of an element, if found. If not found, the result is -(n+1) (or ~n, using bitwise notation), where n is the index where the key should be inserted to maintain the sorting order.
