Detailed Description

The VTK pipeline relies on algorithms providing information about their input and output and responding to requests.

Those metadata are provided through a vtkInformation object, that acts as a dictionary of information. This is a list of keys that information objects use and what each key should be used for.

Information keys usually fall under one of those categories:

data description. Stored in vtkDataObject::GetInformation, those keys are set inside vtkDataObject subclasses when depending on data type only, or in vtkAlgorithm REQUEST_DATA pass to described the data produced.
pipeline available data. Provided during the REQUEST_INFORMATION pass, some keys described the data variants that could be produced like a list of available timesteps or the ability to produce only a subextent of data.
pipeline update request. Provided when updating an algorithm. They can be seen as a generic way to configure the algorithm, for instance to produce a specific timestep or subextent.
pipeline flow control. Those are more internal keys to control the pipeline execution. They are usually not used directly but through dedicated API (for instance UpdateInformation create a request with the REQUEST_INFORMATION key)

There are more use cases not covered here. In fact, arbitrary classes can define new keys for their own purposes.

Function Documentation

◆ GUI_HIDE()

vtkInformationIntegerKey * vtkAbstractArray::GUI_HIDE ( )

static

This key is a hint to end user interface that this array is internal and should not be shown to the end user.

◆ PER_COMPONENT()

vtkInformationInformationVectorKey * vtkAbstractArray::PER_COMPONENT ( )

static

This key is used to hold a vector of COMPONENT_VALUES (and, for vtkDataArray subclasses, COMPONENT_RANGE) keys – one for each component of the array.

You may add additional per-component key-value pairs to information objects in this vector. However if you do so, you must be sure to either (1) set COMPONENT_VALUES to an invalid variant and set COMPONENT_RANGE to {VTK_DOUBLE_MAX, VTK_DOUBLE_MIN} or (2) call ComputeUniqueValues(component) and ComputeRange(component) before modifying the information object. Otherwise it is possible for modifications to the array to take place without the bounds on the component being updated.

◆ PER_FINITE_COMPONENT()

vtkInformationInformationVectorKey * vtkAbstractArray::PER_FINITE_COMPONENT ( )

static

This key is used to hold a vector of COMPONENT_VALUES (and, for vtkDataArray subclasses, COMPONENT_RANGE) keys – one for each component of the array.

You may add additional per-component key-value pairs to information objects in this vector. However if you do so, you must be sure to either (1) set COMPONENT_VALUES to an invalid variant and set COMPONENT_RANGE to {VTK_DOUBLE_MAX, VTK_DOUBLE_MIN} or (2) call ComputeUniqueValues(component) and ComputeFiniteRange(component) before modifying the information object. Otherwise it is possible for modifications to the array to take place without the bounds on the component being updated.

◆ DISCRETE_VALUES()

vtkInformationVariantVectorKey * vtkAbstractArray::DISCRETE_VALUES ( )

static

A key used to hold discrete values taken on either by the tuples of the array (when present in this->GetInformation()) or individual components (when present in one entry of the PER_COMPONENT() information vector).

◆ DISCRETE_VALUE_SAMPLE_PARAMETERS()

vtkInformationDoubleVectorKey * vtkAbstractArray::DISCRETE_VALUE_SAMPLE_PARAMETERS ( )

static

A key used to hold conditions under which cached discrete values were generated; the value is a 2-vector of doubles.

The first entry corresponds to the maximum uncertainty that prominent values exist but have not been detected. The second entry corresponds to the smallest relative frequency a value is allowed to have and still appear on the list.

◆ COMPONENT_RANGE()

vtkInformationDoubleVectorKey * vtkDataArray::COMPONENT_RANGE ( )

static

This key is used to hold tight bounds on the range of one component over all tuples of the array.

Two values (a minimum and maximum) are stored for each component. When GetRange() is called when no tuples are present in the array this value is set to { VTK_DOUBLE_MAX, VTK_DOUBLE_MIN }.

◆ L2_NORM_RANGE()

vtkInformationDoubleVectorKey * vtkDataArray::L2_NORM_RANGE ( )

static

This key is used to hold tight bounds on the $L_2$ norm of tuples in the array.

Two values (a minimum and maximum) are stored for each component. When GetRange() is called when no tuples are present in the array this value is set to { VTK_DOUBLE_MAX, VTK_DOUBLE_MIN }.

◆ L2_NORM_FINITE_RANGE()

vtkInformationDoubleVectorKey * vtkDataArray::L2_NORM_FINITE_RANGE ( )

static

This key is used to hold tight bounds on the $L_2$ norm of tuples in the array.
