KeyView 23.4

# KVMetadataType

DEPRECATED: The `KVMetadataType` enum is deprecated in KeyView 23.2.0 and later. OpenText recommends that you access metadata using the metadata API described in Use the Metadata API.

This enum is still available for existing implementations, but it might be incompatible with new functionality and might be removed in future.

This enumerated type defines the data type of metadata that can be extracted from a subfile in a mail message or mail store. If a metadata field has a corresponding KeyView type in `KVMetadataType`, the metadata is converted to the KVMetadataElem structure, and the structure member `isDataValid` is `1`. This enumerated type is defined in `kvtypes.h`.

## Definition

    typedef enum
    {
      KVMetadata_Unknown       = 0,
      KVMetadata_Bool          = 1,
      KVMetadata_Binary        = 2,
      KVMetadata_Int4          = 3,
      KVMetadata_UInt4         = 4,
      KVMetadata_Int8          = 5,
      KVMetadata_UInt8         = 6,
      KVMetadata_String        = 7,
      KVMetadata_Unicode       = 8,
      KVMetadata_DateTime      = 9,
      KVMetadata_Float         = 10,
      KVMetadata_Double        = 11,
      KVMetadata_Last
    }
    KVMetadataType;

## Enumerators

`KVMetadata_Unknown` | The value in the property is of an unknown type.
`KVMetadata_Bool` | The value in the property is a Boolean value. The corresponding MAPI type is `PT_BOOLEAN`.
`KVMetadata_Binary` | The value in ``the property is a byte array. The corresponding MAPI type is `PT_BINARY`.
`KVMetadata_Int4` | The value in the property is a signed 4-byte integer. The corresponding MAPI types are `PT_I2`, `PT_SHORT`, `PT_I4`, and `PT_LONG`.
`KVMetadata_UInt4` | The value in the property is an unsigned 4-byte integer. This type is not currently supported.
`KVMetadata_Int8` | The value in the property is a signed 8-byte integer. This type is not currently supported.
`KVMetadata_UInt8` | The value in the property is an unsigned 8-byte integer. This type is not currently supported.
`KVMetadata_String` | The value in the property is a string. The corresponding MAPI type is `PT_STRING8`.
`KVMetadata_Unicode` | The value in the property is a Unicode string. The corresponding MAPI type is `PT_UNICODE`.
`KVMetadata_DateTime` | The value in the property is a date and time. The corresponding MAPI type is `PT_SYSTIME`.
`KVMetadata_Float` | The value in the property is a 4-byte float. The corresponding MAPI type is `PT_FLOAT`.
`KVMetadata_Double` | The value in the property is an 8-byte double. The corresponding MAPI type is `PT_DOUBLE`.

## Discussion

New types might be added to this enumerated type. When you use this type, your code should ensure binary compatibility with future releases. See Programming Guidelines.
