The NWDSReadSyntaxDef and NWDSGetSyntaxDef functions use a Syntax_Info_T structure to return information about syntax definitions. The structure uses the following flags to return information about the syntax's matching rules. These flags are ORed together when multiple flags apply to a syntax.
|
Flag |
C Value |
Description |
|---|---|---|
|
DS_STRING |
0x0001 |
Indicates that the syntax can contain string values and therefore attributes with this syntax can be used as naming attributes. |
|
DS_SINGLE_VALUED |
0x0002 |
Indicates that attributes using this syntax can have only one value. |
|
DS_SUPPORTS_ORDER |
0x0004 |
Indicates that attributes using this syntax must be open to comparisons of less than, equal to, and greater than. |
|
DS_SUPPORTS_EQUAL |
0x0008 |
Indicates that attributes using this syntax match for equality when all of the following conditions are met. The attributes' values are identical; the attributes use the same syntax, and the attributes' data type conforms to the syntax. |
|
DS_IGNORE_CASE |
0x0010 |
Indicates that attributes using this syntax ignore case during comparisons. |
|
DS_IGNORE_SPACE |
0x0020 |
Indicates that attributes using this syntax ignore extra space during comparisons. |
|
DS_IGNORE_DASH |
0x0040 |
Indicates that attributes using this syntax ignore dashes during comparisons. |
|
DS_ONLY_DIGITS |
0x0080 |
Indicates that attributes using this syntax must support only digits in their values. |
|
DS_ONLY_PRINTABLE |
0x0100 |
Indicates that attributes using this syntax must support only printable characters in their values. For a list of these characters, see the |
|
DS_SIZEABLE |
0x0200 |
Indicates that attributes using this syntax must set upper and lower limits to their values. |
|
DS_BITWISE_EQUAL |
0x0400 |
Indicates that attributes using this syntax support substring (wildcard) and approximate matching. |
