## Properties

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

## Procedures

- `CreateInStream(): InStream`: Creates an InStream object with default encoding for the TempBlob. This enables you to read data from the TempBlob.
- `CreateInStream(var InStream: InStream)`: Creates an InStream object with default encoding for the TempBlob. This enables you to read data from the TempBlob.
- `CreateInStream(Encoding: TextEncoding): InStream`: Creates an InStream object with default encoding for the TempBlob. This enables you to read data from the TempBlob.
- `CreateInStream(var InStream: InStream; Encoding: TextEncoding)`: Creates an InStream object with the specified encoding for the TempBlob. This enables you to read data from the TempBlob.
- `CreateOutStream(): OutStream`: Creates an OutStream object with default encoding for the TempBlob. This enables you to write data to the TempBlob.
- `CreateOutStream(var OutStream: OutStream)`: Creates an OutStream object with default encoding for the TempBlob. This enables you to write data to the TempBlob.
- `CreateOutStream(Encoding: TextEncoding): OutStream`: Creates an OutStream object with the specified encoding for the TempBlob. This enables you to write data to the TempBlob.
- `CreateOutStream(var OutStream: OutStream; Encoding: TextEncoding)`: Creates an OutStream object with the specified encoding for the TempBlob. This enables you to write data to the TempBlob.
- `HasValue(): Boolean`: Determines whether the TempBlob has a value.
- `Length(): Integer`: Determines the length of the data stored in the TempBlob.
- `FromRecord(RecordVariant: Variant; FieldNo: Integer)`: Copies the value of the BLOB field on the RecordVariant in the specified field to the TempBlob.
- `FromRecordRef(RecordRef: RecordRef; FieldNo: Integer)`: Copies the value of the BLOB field on the RecordRef in the specified field to the TempBlob.
- `ToRecordRef(var RecordRef: RecordRef; FieldNo: Integer)`: Copies the value of the TempBlob to the specified field on the RecordRef.
- `FromFieldRef(BlobFieldRef: FieldRef)`: Copies the value of the FieldRef to the TempBlob.
- `ToFieldRef(var BlobFieldRef: FieldRef)`: Copies the value of the TempBlob to the specified FieldRef.

## 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.

## 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")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
