Retrieves the value of an eight-byte floating-point item (“double” in Java) of a Jolt object attribute. This function is provided to retrieve values from both JoltSessionAttributes and JoltRemoteService object attributes.
Jolt.bdh
JoltGetDouble( in hJolt : number, in sAttribute : string, in fDefault : float, in nOccurrence : number optional): float;
Value of the specified eight-byte floating-point 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 |
fDefault | Floating-point 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
hJolt represents a JoltSessionAttributes object.
