Detailed Description

BLOB extraction class.

This class provides access and processing of HiRISE data as stored in an ISIS BLOB (Table).

Note that the file provided must be a HiRISE ISIS cube file that is freshly converted from a PDS compatable EDR (hi2isis). It must contain an ISIS Table named "HiRISE Calibration Image". From that table, data is extracted from the "Calibration" field.

Member Typedef Documentation

◆ BlobBuf

typedef TNT::Array2D<double> Isis::Blobber::BlobBuf

protectedinherited

Internal buffer uses TNT.

Constructor & Destructor Documentation

◆ HiBlob() [1/2]

Isis::HiBlob::HiBlob ( )

inline

Default, mostly useless constructor.

◆ HiBlob() [2/2]

Isis::HiBlob::HiBlob	(	Cube &	cube,
		const QString &	tblname,
		const QString &	field,
		const QString &	name = `"HiBlob"`
	)

inline

Constructor providing interface to an ISIS Cube object.

◆ ~HiBlob()

virtual Isis::HiBlob::~HiBlob ( )

inlinevirtual

Destructor.

Member Function Documentation

◆ buffer()

const HiMatrix& Isis::HiBlob::buffer ( ) const

inline

Return a reference to the data.

References Isis::Blobber::ref().

Referenced by Isis::HiCalData::load().

◆ deepcopy()

Blobber Isis::Blobber::deepcopy ( ) const

inherited

Create a unique copy of this blob.

This method creates a fully new copy of this object. The default copy constructors/methods create a reference to the data read from the Table object. For example, the following code fragment will result in two Blobbers that refer to the same memory location that stores the BLOB data:

Blobber myblob = yourblob;

To ensure you have two unique storage areas of the BLOB data so they can change independantly, use:

Blobber myblob = yourblob.deepcopy();

Returns: (Blobber) Returns a completely new copy, including data, to caller.

◆ getBlobName()

QString Isis::Blobber::getBlobName ( ) const

inlineinherited

Retrieves the name of the Table object.

Returns: (string) Name of the Table

Referenced by Isis::Blobber::load().

◆ getFieldName()

QString Isis::Blobber::getFieldName ( ) const

inlineinherited

Retreive the name of the field in the Tabel object BLOB.

Returns: (string) Name of the BLOB field

Referenced by Isis::Blobber::load().

◆ getName()

QString Isis::Blobber::getName ( ) const

inlineinherited

Returns the name of the BLOB given to refer to this instantiation.

Returns: Name of BLOB instance

◆ Lines()

int Isis::Blobber::Lines ( ) const

inlineinherited

Number of rows or lines in the BLOB.

Returns: The lines or rows

Referenced by Isis::Blobber::size().

◆ load() [1/2]

void Isis::Blobber::load ( const QString & filename )

inherited

Loads the contents of a BLOB from a cube file.

Provides the I/O interface for ISIS cube files.

Parameters

[in] filename (string&) Name of ISIS cube file to read

References Isis::Cube::open().

Referenced by Isis::Blobber::Blobber().

◆ load() [2/2]

void Isis::Blobber::load ( Cube & cube )

inherited

Loads the contents of a BLOB from a Cube object.

Provides the I/O interface for the Cube object. One thing to note here is that it creates a CubeInfo object from the Cube object and then calls the CubeInfo load method. Hence, this method is required as an intermediary method that cascades to the actual method that does the real work.

Parameters

[in] cube (Cube&) Reference to an ISIS cube file that has been opened or created in the Cube object.

References _FILEINFO_, Isis::Blobber::getBlobName(), Isis::Blobber::getFieldName(), Isis::TableField::isDouble(), Isis::TableField::isInteger(), Isis::IException::Programmer, and Isis::Cube::read().

◆ operator[]() [1/2]

double* Isis::Blobber::operator[] ( int i )

inlineinherited

Returns the ith row/line in the BLOB that can be further referenced into samples.

To access the 2nd sample in the 10th line use:

double sample = blobber[9][1];

Parameters

i Index

Returns: Pointer to the ith row in the BLOB

◆ operator[]() [2/2]

double const* Isis::Blobber::operator[] ( int i ) const

inlineinherited

Returns the ith row/line in the BLOB that can be further referenced into samples.

This method provides const access to the data in row matrix form. To access the 2nd sample in the 10th line use:

double sample = blobber[9][1];

Parameters

i Index

Returns: Const pointer to the ith row in the BLOB

◆ ref()

const BlobBuf& Isis::Blobber::ref ( ) const

inlineprotectedinherited

Returns a const reference to the internal buffer for ease of use to derived objects.

Returns: Const reference to BLOB buffer

Referenced by buffer().

◆ Samples()

int Isis::Blobber::Samples ( ) const

inlineinherited

Number of columns or samples in the BLOB.

Returns: The number of samples or columns

Referenced by Isis::Blobber::size().

◆ setBlobName()

void Isis::Blobber::setBlobName ( const QString & bname )

inlineinherited

Sets the name of the ISIS BLOB object that contains the data.

This is name of a ISIS Table object that contains one or more fields that make up the BLOB. This is the value of the [i]Name[/i] keyword in the Table object.

Parameters

bname Blobber name

◆ setFieldName()

void Isis::Blobber::setFieldName ( const QString & fname )

inlineinherited

Sets field name in the ISIS BLOB object that contains data.

This method sets the name of the field contained within the Table object BLOB from which the data is extracted.

Parameters

fname Field name

◆ setName()

void Isis::Blobber::setName ( const QString & name )

inlineinherited

Specifies the name of this class instantiation.

This is just an additional name that can be used to identify instantiations of this class. It provides a way to uniquely identify each object.

Parameters

name	Unique name

◆ size()

int Isis::Blobber::size ( ) const

inlineinherited

Returns the total number of elements (rows * columns) in blob.

Returns: The product of rows and columns
