The Custom Wire Format properties described here apply to:
Property | Type | Meaning |
---|---|---|
Physical Type | Enumerated Type | Select one of the following from the drop-down list:
The representation of numeric elements can be affected by the Encoding and CodedCharSetId attributes that are set for the WebSphere MQ queue manager:
|
Length Count | Integer | Enter
the number of bytes to specify the element length:
|
Length Units | Enumerated Type | Subject to the Physical
Type that has been set, select one of the following from the
drop-down list:
The default is bytes. |
Signed | Boolean | Select (the default) or deselect this property. This property is used in conjunction with Sign Orientation. |
Sign Orientation | Enumerated Type | If you have set Physical
Type to External Decimal and
you have selected Signed,
choose from the following options that represent the COBOL options for displaying
numeric data:
|
Virtual Decimal Point | Integer | Specify the number of places to the left (for a positive value) or right (for a negative value) that a decimal point should be moved from its assumed position. For example, a decimal element containing 1234 with a Virtual Decimal value of 3 is 1.234. This is equivalent to 'V' or 'P' in a COBOL picture clause. There is no C equivalent |
String Justification | Enumerated Type | If you have set the Physical Type property to External Decimal, select Left Justify or Right Justify (the default value) from the drop-down list. If you have selected another value for Physical Type, this is property is inactive. |
Padding Character | String | The
padding character is used to fill out the remaining character positions when
the string length is less than the specified string size. If you have set
the Physical Type property
to Extended
Decimal, and the String
Justification property is either Left
Justify or Right Justify,
set this character in one of the following ways:
|
Property | Type | Meaning |
---|---|---|
Encoding Null | Enumerated Type | Select
one of the following options from the drop-down list:
|
Encoding Null Value | String | The use of this property depends on the Encoding Null property, described above. The default value is zero. |
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 Count | Button and Integer | If you have selected the Repeat Count property, enter the number of occurrences for this object. The minimum value is 0 (zero and one mean that a single occurrence is expected), the maximum value is 2147483647. |
Repeat Reference | Button and Enumerated Type | If you have selected the Repeat
Reference property, select the name of the integer object the
value of which specifies the number of occurrences of this object from the
drop-down list of integer objects that are defined as siblings of the current
object, and occur before it in the structure of the message. For information about reordering elements, see Reordering objects. |
