## Properties

| Property | Value |
|---|---|
| Access | Public |

## Procedures

- `Exists(Index: Integer): Boolean`: Check if an element with the given index exists.
- `Count(): Integer`: Returns the number of elements in the list.
- `Get(Index: Integer; var TempBlob: Codeunit "Temp Blob")`: Get an element from the list at any given position.
- `Set(Index: Integer; TempBlob: Codeunit "Temp Blob"): Boolean`: Set an element at the given index from the parameter TempBlob.
- `RemoveAt(Index: Integer): Boolean`: Remove the element at a specified location from a non-empty list.
- `RemoveRange(Index: Integer; ElementCount: Integer): Boolean`: Remove a number of elements starting from a specified location from a non-empty list.
- `IsEmpty(): Boolean`: Return true if the list is empty, otherwise return false.
- `Add(TempBlob: Codeunit "Temp Blob"): Boolean`: Adds a TempBlob to the end of the list.
- `AddRange(TempBlobList: Codeunit "Temp Blob List"): Boolean`: Adds the elements of the specified TempBlobList to the end of the current TempBlobList object.
- `GetRange(Index: Integer; ElemCount: Integer; var TempBlobListOut: Codeunit "Temp Blob List")`: Get a copy of a range of elements in the list starting from index,

## Calls

From the extracted call graph of BC29 (graphify-al on the snapshot checkout): calls whose target is known from a declared type or an `Object::"Name"` argument. Interface dispatch and calls through events are not counted, so the list is not complete.

- [Codeunit 4109 "Temp Blob List Impl."](../codeunit/4109.md) (10 calls: `Add → Add`, `AddRange → AddRange`, `Count → (object)`, …)

## Called by

- [Codeunit 8800 "Custom Layout Reporting"](../codeunit/8800.md) (5 calls: `GetRequestParametersText → Get`, `GetViewFromParameters → Get`, `StoreRequestParameters → (object)`, …)
- [Codeunit 884 "ReadSoft OCR Master Data Sync"](../codeunit/884.md) (5 calls: `AddToBuffer → Add`, `GetMasterDataEntitiesXml → (object)`, `GetMasterDataEntitiesXml → Get`, …)
- [Codeunit 4109 "Temp Blob List Impl."](../codeunit/4109.md) (4 calls: `AddRange → (object)`, `AddRange → Get`, `AddRange → IsEmpty`, …)
- [Codeunit 9520 "Mail Management"](../codeunit/9520.md) (4 calls: `DownloadPdfAttachment → (object)`, `DownloadPdfAttachment → Get`, `SendViaEmailModule → (object)`, …)
- [Codeunit 260 "Document-Mailing"](../codeunit/260.md) (2 calls: `EmailFileInternal → (object)`, `EmailFileInternal → Get`)

Source: AL metadata extracted from the code (names, ids, signatures, properties); no code bodies (D10).

## Ask your agent

Procedure bodies are not stored here (D10). The call sections above are our own, per object, from the BC29 call graph. For a procedure body or the calls of one procedure, ask bc-code-atlas (external, by Stefan Maron, MIT; default corpus w1-28), which the bc-observatory plugin connects: `bcatlas_resolve_node(object_type: "codeunit", object_name: "Temp Blob List")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
