## Properties

| Property | Value |
|---|---|
| Caption | CSV Buffer |
| DataClassification | CustomerContent |

## Fields

Explanation: the field's ToolTip in the code; without one, the ToolTip of a page control bound to the field (marked via the page); without that, its Caption (marked caption) when that differs from the name.

| No. | Name | Type | Explanation | Notes |
|---|---|---|---|---|
| 1 | Line No. | Integer | — | DataClassification SystemMetadata |
| 2 | Field No. | Integer | — | DataClassification SystemMetadata |
| 3 | Value | Text[250] | — | DataClassification SystemMetadata |

## Keys

- Key1: Line No., Field No. (clustered)

## Procedures

- `InsertEntry(LineNo: Integer; FieldNo: Integer; FieldValue: Text[250])`: Inserts an entry to the record.
- `LoadData(CSVFileName: Text; CSVFieldSeparator: Text[1]; CSVCharactersToTrim: Text)`: Loads data from a file.
- `LoadData(CSVFileName: Text; CSVFieldSeparator: Text[1])`: Loads data from a file.
- `LoadDataFromStream(CSVInStream: InStream; CSVFieldSeparator: Text[1]; CSVCharactersToTrim: Text)`: Loads data from a stream.
- `LoadDataFromStream(CSVInStream: InStream; CSVFieldSeparator: Text[1])`: Loads data from a stream.
- `SaveData(CSVFileName: Text; CSVFieldSeparator: Text[1])`: Saves the data stored in the record to a file.
- `SaveDataToBlob(var TempBlob: Codeunit "Temp Blob"; CSVFieldSeparator: Text[1])`: Saves the data stored in the record to a BLOB.
- `InitializeReader(CSVFileName: Text; CSVFieldSeparator: Text[1])`: Initializes the CSV buffer.
- `InitializeReader(CSVFileName: Text; CSVFieldSeparator: Text[1]; CSVCharactersToTrim: Text)`: Initializes the CSV buffer.
- `InitializeReader(CSVFileName: Text; CSVFieldSeparator: Text[1]; CSVCharactersToTrim: Text; Encoding: DotNet Encoding)`: Initializes the CSV buffer.
- `InitializeReaderFromStream(CSVInStream: InStream; CSVFieldSeparator: Text[1]; CSVCharactersToTrim: Text)`: Initializes the CSV buffer.
- `InitializeReaderFromStream(CSVInStream: InStream; CSVFieldSeparator: Text[1])`: Initializes the CSV buffer.
- `LoadDataFromStream(CSVInStream: InStream; CSVFieldSeparator: Text[1]; EncodingCodePage: Integer)`: Loads data from a stream.
- `LoadDataFromStream(CSVInStream: InStream; CSVFieldSeparator: Text[1]; CSVCharactersToTrim: Text; EncodingCodePage: Integer)`: Loads data from a stream.
- `InitializeReaderFromStream(CSVInStream: InStream; CSVFieldSeparator: Text[1]; CSVCharactersToTrim: Text; EncodingCodePage: Integer)`: Initializes the CSV buffer.
- `ReadLines(NumberOfLines: Integer): Boolean`: Populated the CSV buffer with entries.
- `ResetFilters()`: Resets the filters on the record.
- `GetValue(LineNo: Integer; FieldNo: Integer): Text[250]`: Gets a value from the record.
- `GetCSVLinesWhere(FilterFieldNo: Integer; FilterValue: Text; var TempResultCSVBuffer: Record "CSV Buffer" temporary)`: Gets all the lines that contain a specific value on a specific field/position.
- `GetValueOfLineAt(FieldNo: Integer): Text[250]`: Gets the value on the current line with a specific field number (or position).
- `GetValueOfLineAt(FieldNo: Integer; AcceptNonExisting: Boolean): Text[250]`: Gets the value on the current line with a specific field number (or position).
- `GetNumberOfColumns(): Integer`: Gets the number of columns store in the record.
- `GetNumberOfLines(): Integer`: Gets the number of lines stored in the record.

Plus 1 local procedures.

## 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 4100 "Temp Blob"](../codeunit/4100.md) (1 call: `SaveDataToBlob → CreateOutStream`)
- [Codeunit 419 "File Management"](../codeunit/419.md) (1 call: `SaveData → IsAllowedPath`)

## Across versions

- Present in: BC23-30
- Changed (declaration) in: BC24-25

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: "table", object_name: "CSV Buffer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
