CWF properties for attribute reference and local attribute Boolean types

The Custom Wire Format properties described here apply to:

Byte alignment

Property Type Meaning
Byte Alignment Enumerated type Specify how the object is aligned from the start of the message. Select one of:
  • 1 Bytes. This is the default value.
  • 2 Bytes
  • 4 Bytes
  • 8 Bytes
  • 16 Bytes
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.
