Detailed Description

This class can be used to define import/export behavior of Pvl structures when used in the PvlFlatMap class.

The include/exclude features are applied to PvlObject and PvlGroup structures.

The keylists apply only to keywords.

Behavior beyond what is provided here is the burden of the programmer.

A complete Pvl structure can be provided in the PvlFlatMap class along with a defined PvlConstraints class containing objects/groups that are included or excluded from import operations. Additionally, users can restrict the contents of all keyword containers to a list of keywords as provided in the keylist in this class. It applies to all PVL keyword containers so ensure the list is comprehensive to include all desired keywords from all containers.

Note if any include containers names are specified, all others are excluded by definition. Likewise, if any containers are excluded, all other keywords containers are included by definition. This behavior is defined to be constrained to the PvlObject and/or PvlGroup levels.

A special mode can be defined by using both the include and exclude feature in combination. Include names are preimenent in this mode including only those PVL structures in the include list and excluding PVL structures in the exclude list. If any keywords exist in the keylist, then they are the only keywords mapped from the PVL stuctures in the include list.

Note that if a PvlGroup/PvlObject is excluded, then every PvlGroup/PvlObject contained within it are also excluded. Similarly, in order for a PvlGroup/PvlObject to be included, then any PvlObject that it is contained in must also be included.

Example PVL:

Object = IsisCube
  Object = Core
    StartByte   = 65537
    Format      = Tile
    TileSamples = 128
    TileLines   = 128
 
    Group = Dimensions
      Samples = 704
      Lines   = 3640
      Bands   = 5
    End_Group
 
    Group = Pixels
      Type       = Real
      ByteOrder  = Lsb
      Base       = 0.0
      Multiplier = 1.0
    End_Group
  End_Object
 
  Group = Instrument
    SpacecraftName            = "LUNAR RECONNAISSANCE ORBITER"
    InstrumentId              = WAC-VIS
    TargetName                = Moon
    StartTime                 = 2009-09-15T07:27:49.230
  End_Group
 
  Group = Archive
    DataSetId            = LRO-L-LROC-2-EDR-V1.0
    ProducerId           = LRO_LROC_TEAM
    ProductId            = M107638937CE
  End_Group
 
  Group = BandBin
    FilterNumber = (3, 4, 5, 6, 7)
    Center       = (415, 566, 604, 643, 689)
  End_Group
 
End_Object

For the example PVL above, we can do the following:

1) Exclude the Pixels group

PvlConstraints constraints;

constraints.addExclude("Pixels");

Isis::PvlConstraints

This class can be used to define import/export behavior of Pvl structures when used in the PvlFlatMap...

Definition PvlFlatMap.h:150

Isis::PvlConstraints::addExclude

void addExclude(const QString &name)

Adds a PvlObject/PvlGroup exclusion constraint.

Definition PvlFlatMap.cpp:134

2) Include the Pixels group.

PvlConstraints constraints; 
constraints.addInclude("IsisCube"); 
constraints.addInclude("Core"); 
constraints.addInclude("Pixels"); 

3) The following will include everything in the Core object (Pixels, Dimensions, and Core keywords).

PvlConstraints constraints; 
constraints.addInclude("IsisCube"); 
constraints.addInclude("Core"); 

4) In some cases we will have a mix of includes/excludes.

PvlConstraints constraints; 
constraints.addInclude("IsisCube"); 
constraints.addInclude("Core"); 
constraints.addExclude("Pixels");

◆ addExclude() [1/2]

void Isis::PvlConstraints::addExclude ( const QString & name )

Adds a PvlObject/PvlGroup exclusion constraint.

By providing the name of a PvlObject or PvlGroup object, the object will be excluded when creating a PvlFlatMap from a Pvl structure.

Note that if this structure is contained within a PvlObject, then excluding the top level object also excludes all subgroups/subobjects contained within.

◆ addInclude() [1/2]

void Isis::PvlConstraints::addInclude ( const QString & name )
