public interface CommonDMIMapper<S>
A common mapping interface for converting raw dmidecode output into strongly typed Java objects.

Provides default methods to parse structured DMI text data and map it into either:

  • a single Optional entity
  • a List of entities when multiple DMI blocks are present

The mapping process works by:

  1. Parsing key–value pairs from the raw DMI text
  2. Normalizing single-line and multi-line values
  3. Converting the extracted data into JSON internally
  4. Deserializing the JSON into the requested entity class using Jackson

    • mapToEntity

      @FragileMethod(type=INTERFACE_DEFAULT_METHOD, reason="Parsing formatted human readable dmidecode output is always error-prone and subject to change without notice", requiresReplacement=true, replacementNote="Consider using --json flag of dmidecode if available") default @NonNull Optional<S> mapToEntity(@Nullable String rawDMIData, @NonNull Class<S> mappableEntityClass)
      Maps raw dmidecode output into a single entity of type <S>.

      If multiple DMI blocks are present in the input, the last parsed entity is returned.

      Multi-line values (for example, lists under keys like Flags: or Characteristics:) are automatically aggregated into lists.

      Example schema:

       # dmidecode 3.6
 Getting SMBIOS data from sysfs.
 SMBIOS 3.3.0 present.

 Processor Information
     Socket Designation: FP6
     Type: Central Processor
     Family: Zen
     Flags:
         FPU (Floating-point unit on-chip)
         VME (Virtual mode extension)
     Version: AMD Ryzen 3 5300U with Radeon Graphics
     Characteristics:
         64-bit capable
         Multi-Core
      Parameters:
      rawDMIData - the raw dmidecode output
      mappableEntityClass - the target entity class
      Returns:
      an Optional containing the mapped entity, or empty if no mappable data is found

    • mapToList

      @FragileMethod(type=INTERFACE_DEFAULT_METHOD, reason="Parsing formatted human readable dmidecode output is always error-prone and subject to change without notice", requiresReplacement=true, replacementNote="Consider using --json flag of dmidecode if available") default @NonNull @Unmodifiable List<S> mapToList(@Nullable String rawDMIData, @NonNull Class<S> mappableEntityClass)
      Maps raw dmidecode output into a list of entities of type <S>.

      Each DMI block separated by a blank line is treated as an independent entity. Empty or non-mappable blocks are ignored.

      This method is useful for DMI structures that naturally occur multiple times, such as cache information, memory devices, or processor entries.

      Example schema:

       # dmidecode 3.6
 Getting SMBIOS data from sysfs.
 SMBIOS 3.3.0 present.
