## Properties

| Property | Value |
|---|---|
| Caption | JSON 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 | Entry No. | Integer | — | DataClassification SystemMetadata |
| 2 | Depth | Integer | — | DataClassification SystemMetadata |
| 3 | Token type | Option | — | OptionCaption: None,Start Object,Start Array,Start Constructor,Property Name,Comment,Raw,Integer,Decimal,String,Boolean,Null,Undefined,End Object,End Array,End Constructor,Date,Bytes; DataClassification SystemMetadata |
| 4 | Value | Text[250] | — | DataClassification SystemMetadata |
| 5 | Value Type | Text[50] | — | DataClassification SystemMetadata |
| 6 | Path | Text[250] | — | DataClassification SystemMetadata |
| 7 | Value BLOB | BLOB | — | DataClassification SystemMetadata |

## Keys

- Key1: Entry No. (clustered)

## Procedures

- `ReadFromBlob(BlobFieldRef: FieldRef)`
- `ReadFromText(JSONText: Text)`
- `FindArray(var TempJSONBuffer: Record "JSON Buffer" temporary; ArrayName: Text): Boolean`
- `GetPropertyValue(var PropertyValue: Text; PropertyName: Text): Boolean`
- `GetPropertyValueAtPath(var PropertyValue: Text; PropertyName: Text; PropertyPath: Text): Boolean`
- `GetBooleanPropertyValue(var BooleanValue: Boolean; PropertyName: Text): Boolean`
- `GetIntegerPropertyValue(var IntegerValue: Integer; PropertyName: Text): Boolean`
- `GetDatePropertyValue(var DateValue: Date; PropertyName: Text): Boolean`
- `GetDecimalPropertyValue(var DecimalValue: Decimal; PropertyName: Text): Boolean`
- `GetValue(): Text`
- `SetValue(NewValue: Text)`
- `SetValueWithoutModifying(NewValue: Text)`

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 10 "Type Helper"](../codeunit/10.md) (4 calls: `GetValue → LFSeparator`, `GetValue → ReadAsTextWithSeparator`, `ReadFromBlob → CRLFSeparator`, …)
- [Codeunit 4100 "Temp Blob"](../codeunit/4100.md) (2 calls: `ReadFromBlob → CreateInStream`, `ReadFromBlob → FromRecordRef`)

## Across versions

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

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: "JSON Buffer")`, then `bcatlas_get_procedure_body` or `bcatlas_get_neighbors` on the returned id.
