# Function: createWrapperFunction()
|
|
|
|
> **createWrapperFunction**(`analyzer`, `name`, `node`): `string` \| `undefined`
|
|
|
|
Analyzes an AST node to determine if it's a function call or a function
|
|
declaration. Based on that, it then creates a new JavaScript function as
|
|
a string. This new function acts as a wrapper, taking a single 'input'
|
|
argument and forwarding it to the original function call.
|
|
|
|
Currently can handle:
|
|
- `CallExpression`: Creates a wrapper that invokes the function being called in the expression.
|
|
- `VariableDeclarator` with a `FunctionExpression`: Creates a wrapper that calls the declared function.
|
|
|
|
## Parameters
|
|
|
|
• **analyzer**: [`JsAnalyzer`](../../Types/classes/JsAnalyzer.md)
|
|
|
|
The `JSAnalyzer` instance, used to resolve context like declared variables.
|
|
|
|
• **name**: `string`
|
|
|
|
The name for the new wrapper function to be created.
|
|
|
|
• **node**: `Node`
|
|
|
|
The ESTree node.
|
|
|
|
## Returns
|
|
|
|
`string` \| `undefined`
|
|
|
|
## Todo
|
|
|
|
Look for edge cases.
