Retrieves the value of a one-byte item (“byte” in Java) of a Jolt object attribute. This function is provided to retrieve values from both JoltSessionAttributes and JoltRemoteService object attributes.
Jolt.bdh
JoltGetByte( in hJolt : number, in sAttribute : string, in nDefault : number, in nOccurrence : number optional ): number;
Value of the specified one-byte item of the Jolt object attribute.
Parameter | Description |
---|---|
hJolt | Handle to a JoltSessionAttributes or JoltRemoteService object that was created with JoltSessionAttributesNew or JoltRemoteServiceNew, respectively |
sAttribute | Name of the attribute that is to be accessed |
nDefault | Value that the function returns if the specified attribute or item does not exist |
nOccurrence |
Index of the item that is to be retrieved (optional). The index of an attribute’s first item is 1 (not 0). If this parameter is omitted, the attribute’s first item is retrieved. Note: This parameter is ignored if
