## Methods

`void AddVariablesToDefaultCompleterIfEnable(IEnumerable<AutocompleteVariable> variables)` 

Adds the provided variables to the [DefaultAutocompleter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.CodeAutocomplete/DefaultAutocompleter/) when the default autocompleter is available. If the [DefaultAutocompleter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.CodeAutocomplete/DefaultAutocompleter/) is not added, the method does nothing. If it is available but not yet initialized, this method initializes it before adding variables.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `variables` | `IEnumerable<AutocompleteVariable>` | Variables to add to the default autocomplete source. |

`void AddVariablesToDefaultCompleterIfEnable(string varName, Type varType)` 

Adds a variable to the [DefaultAutocompleter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.CodeAutocomplete/DefaultAutocompleter/) when the default autocompleter is available. If the [DefaultAutocompleter](https://api.workflowengine.io/core/OptimaJet.Workflow.Core.Runtime.CodeAutocomplete/DefaultAutocompleter/) is not added, the method does nothing. If it is available but not yet initialized, this method initializes it before adding the variable.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `varName` | `String` | Variable name that should appear in autocomplete results. |
| `varType` | `Type` | Variable runtime type used for completion candidates. |

`HashSet<AutocompleteItem> Get(string pattern, IEnumerable<string> usings, IEnumerable<AutocompleteVariable> variables)` 

Gets completion entries from all autocompleters that are already initialized.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `pattern` | `String` | Text pattern to match, for example `System.Thr`. |
| `usings` | `IEnumerable<String>` | Namespace aliases in scope, such as `System` or `System.Threading`. |
| `variables` | `IEnumerable<AutocompleteVariable>` | Variables that can be suggested during completion. |

### Returns

| Type | Description |
| --- | --- |
| `HashSet<AutocompleteItem>` | A set of matching autocomplete items. |

`void InitCodeAutocomletersThatNoInitialized()` 

Initializes each registered autocompleter that is not yet initialized.

`void RegisterCodeAutocompleters(params ICodeAutocompleter[] completers)` 

Registers additional code autocompleters without initializing them.

### Parameters

| Name | Type | Description |
| --- | --- | --- |
| `completers` | `ICodeAutocompleter[]` | Autocompleter instances to add to the provider collection. |

`void RunInitTask()` 

Starts an asynchronous task that initializes registered autocompleters.
