## ArgumentType type
|

## buildExpression() function
|
||||
|
||||
Makes it easy to progressively build, update, and traverse an expression AST. You can either start with an empty AST, or provide an expression string, AST, or array of expression function builders to use as initial state.
|
||||
|
||||
<b>Signature:</b>
|
||||
|
||||
```typescript
|
||||
export declare function buildExpression(initialState?: ExpressionAstFunctionBuilder[] | ExpressionAstExpression | string): ExpressionAstExpressionBuilder;
|
||||
```
|
||||
|
||||
## Parameters
|
||||
|
||||
| Parameter | Type | Description |
|
||||
| --- | --- | --- |
|
||||
| initialState | <code>ExpressionAstFunctionBuilder[] | ExpressionAstExpression | string</code> | |
|
||||
|
||||
<b>Returns:</b>
|
||||

|
||||
|
||||
## buildExpressionFunction() function
|
||||
|
||||
Manages an AST for a single expression function. The return value can be provided to `buildExpression` to add this function to an expression.
|
||||
|
||||
Note that to preserve type safety and ensure no args are missing, all required arguments for the specified function must be provided up front. If desired, they can be changed or removed later.

<b>Signature:</b>

|

```typescript
|

export declare function buildExpressionFunction<FnDef extends AnyExpressionFunctionDefinition = AnyExpressionFunctionDefinition>(fnName: InferFunctionDefinition<FnDef>['name'],

Allows to fetch saved objects from ElasticSearch. In browser `getSavedObject` function is provided automatically by the Expressions plugin. On the server the caller of the expression has to provide this context function. The reason is because on the browser we always know the user who tries to fetch a saved object, thus saved object client is scoped automatically to that user. However, on the server we can scope that saved object client to any user, or even not scope it at all and execute it as an "internal" user.
