The Custom Wire Format properties described here apply to:
Property | Type | Meaning |
---|---|---|
Byte Alignment | Enumerated type | Specify how the object is aligned from the start of
the message. Select one of:
|
Leading Skip Count | Integer | Specify the number of bytes to skip before reading or
writing this object. The default is 0,
the minimum value is 0,
and the maximum value is 999999.
You can use this value to ignore unwanted fields in a structure, or to model
a field defined by C or COBOL data which requires alignment on a 2, 4, 8 or
16 byte boundary. Specify the number of bytes to skip before reading or writing
this object. When an output message is written, Skip Count bytes are assigned
the value of the message set Byte Alignment Pad property. For repeating objects, this property is applied to the first instance only. |
Trailing Skip Count | Integer | Specify the number of bytes to skip after reading or
writing this object. The default is 0,
the minimum value is 0,
and the maximum value is 999999.
You can use this value to ignore unwanted fields in a structure, or to model
a repeating structure containing fields which require alignment on a 2, 4,
8 or 16 byte boundary. When an output message is written, Skip Count bytes
are assigned the value of the message set Byte Alignment Pad property. For repeating objects, this property is applied to all instances. |
Property | Type | Meaning |
---|---|---|
Repeat Reference | Enumerated type | Use this property if the object occurs multiple times, and the number
of occurrences is given dynamically by a field earlier in the message. Select an integer object from the drop-down list of integer objects that occur before this object in the structure of the message. The value of the selected integer specifies the number of occurrences of this object. If no objects are listed, there are no integer objects prior to this one in the message structure. If a Repeat Reference is specified, it overrides any setting for the Max Occurs logical property when parsing and writing the message, but not for validation of the message. |
