This patch allows for registration and recognition of reserved values which are ranges, so they're composed of two values actually to denote the lower and upper bound for the range (stored as an array with exactly two items to define the boundaries). Also, this patch allows for flagging reserved values as named-only which means that such values are not strictly reserved. The strictly reserved values are reserved values as used before this patch. Distinction between strictly-reserved and named-only values is clearly visible with comparisons. Normally, strictly reserved value is not accounted for if we do "greater than" or "lower than" comparisons, for example: 1 2 3 .... | abc - we have "abc" as reserved value for field with value "2" - the value reported for the field is "abc" (or "2", it doesn't matter here) - the selection we're processing is -S 'field < abc' - the result of the selection gives nothing as "abc" is strictly reserved value (bound to "2") and there's no order defined for it and it would only match if we directly compared the value (so -S 'field = abc' would match) With named-only values, the "abc" is named-only value for "2", so selection -S 'field < abc" is the same as using -S 'field < 2'. The "abc" is just an alias for some value so the value or its assigned name can be used equally in selection criteria.

* This file defines reserved names for field values.
|
|
*
|
|
* This is used for registering reserved names with reporting code that
|
|
* uses the exact value defined whenever the reserved name is hit, for
|
|
* example during selection criteria processing.
|
|
*
|
|
* TYPE_RESERVED_VALUE defines reserved value that is not bound to any field,
|
|
* but rather it's bound to a certain type. This can be used as a reserved
|
|
* value for all fields of that type then. When naming type reserved value,
|
|
* please follow this naming scheme:
|
|
* <report type name in lowercase>_<reserved_value_name>
|
|
*
|
|
* FIELD_RESERVED_VALUE defines reserved value bound to a single field.
|
|
* When naming reserved value for the field, please follow this naming scheme:
|
|
* <field_name>_<reserved_value_name>
|
|
*
|
|
* FIELD_BINARY_RESERVED_VALUE is similar to FIELD_RESERVED_VALUE but it
|
|
* is specifically designed for defintion of reserved names for fields
|
|
* with binary values where the reserved names given denote value 1.
|
|
* The first reserved_name given is also used for reporting,
|
|
* others are synonyms which are recognized in addition.
