Detailed Description

Store on/off settings for data arrays, etc.

vtkDataArraySelection is intended to be used by algorithms that want to expose a API that allow the user to enable/disable a collection of entities, such as arrays. Readers, for example, can use vtkDataArraySelection to let the user choose which array to read from the file.

Originally intended for selecting data arrays (hence the name), this class can be used for letting users choose other items too, for example, vtkIOSSReader uses vtkDataArraySelection to let users choose which blocks to read.

Unlike most other vtkObject subclasses, vtkDataArraySelection has public API that need not modify the MTime for the object. These M-Time non-modifying methods are typically intended for use within the algorithm or reader to populate the vtkDataArraySelection instance with available array names and their default values.

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObjectBase.

◆ New()

static vtkDataArraySelection * vtkDataArraySelection::New ( )
static

◆ EnableArray()

void vtkDataArraySelection::EnableArray ( const char *  name)

Enable the array with the given name.

Creates a new entry if none exists.

This method will call this->Modified() if the enable state for the array changed.

◆ DisableArray()

void vtkDataArraySelection::DisableArray ( const char *  name)

Disable the array with the given name.

Creates a new entry if none exists.

This method will call this->Modified() if the enable state for the array changed.

◆ ArrayIsEnabled()

int vtkDataArraySelection::ArrayIsEnabled ( const char *  name) const

Return whether the array with the given name is enabled.

If there is no entry, the array is assumed to be disabled.

◆ ArrayExists()

int vtkDataArraySelection::ArrayExists ( const char *  name) const

Return whether the array with the given name exists.

◆ EnableAllArrays()

void vtkDataArraySelection::EnableAllArrays ( )

Enable all arrays that currently have an entry.

This method will call this->Modified() if the enable state for any of the known arrays is changed.

◆ DisableAllArrays()

void vtkDataArraySelection::DisableAllArrays ( )

Disable all arrays that currently have an entry.

This method will call this->Modified() if the enable state for any of the known arrays is changed.

◆ GetNumberOfArrays()

int vtkDataArraySelection::GetNumberOfArrays ( ) const

Get the number of arrays that currently have an entry.

◆ GetNumberOfArraysEnabled()

int vtkDataArraySelection::GetNumberOfArraysEnabled ( ) const

Get the number of arrays that are enabled.

◆ GetArrayName()

const char * vtkDataArraySelection::GetArrayName ( int  index) const

Get the name of the array entry at the given index.

◆ GetArrayIndex()

int vtkDataArraySelection::GetArrayIndex ( const char *  name) const

Get an index of the array with the given name.

◆ GetEnabledArrayIndex()

int vtkDataArraySelection::GetEnabledArrayIndex ( const char *  name) const

Get the index of an array with the given name among those that are enabled.

Returns -1 if the array is not enabled.

◆ GetArraySetting() [1/2]

int vtkDataArraySelection::GetArraySetting ( int  index) const

Get whether the array at the given index is enabled.

◆ GetArraySetting() [2/2]

int vtkDataArraySelection::GetArraySetting ( const char *  name) const
inline

Get whether the array is enabled/disable using its name.

Definition at line 122 of file vtkDataArraySelection.h.

◆ SetArraySetting()

void vtkDataArraySelection::SetArraySetting ( const char *  name,
int  setting 
)

Set array setting given the name.

If the array doesn't exist, it will be added.

This method will call this->Modified() if the enable state for the array changed.

◆ RemoveAllArrays()

void vtkDataArraySelection::RemoveAllArrays ( )

Remove all array entries.

This method will call this->Modified() if the arrays were cleared.

◆ AddArray()

int vtkDataArraySelection::AddArray ( const char *  name,
bool  state = true 
)

Add to the list of arrays that have entries.

For arrays that already have entries, the settings are untouched. For arrays that don't already have an entry, they are assumed to be enabled by default. The state can also be passed as the second argument. This method should be called only by the filter owning this object.

This method does not call this->Modified().

Also note for arrays already known to this instance (i.e. this->ArrayExists(name) == true, this method has no effect.

◆ RemoveArrayByIndex()

void vtkDataArraySelection::RemoveArrayByIndex ( int  index)

Remove an array setting given its index.

This method does not call this->Modified().

◆ RemoveArrayByName()

void vtkDataArraySelection::RemoveArrayByName ( const char *  name)

Remove an array setting given its name.

This method does not call this->Modified().

◆ SetArrays()

void vtkDataArraySelection::SetArrays ( const char *const *  names,
int  numArrays 
)

Set the list of arrays that have entries.

For arrays that already have entries, the settings are copied. For arrays that don't already have an entry, they are assigned the given default status. If no default status is given, it is assumed to be on. There will be no more entries than the names given. This method should be called only by the filter owning this object. The signature with the default must have a different name due to a bug in the Borland C++ 5.5 compiler.

This method does not call this->Modified().

◆ SetArraysWithDefault()

void vtkDataArraySelection::SetArraysWithDefault ( const char *const *  names,
int  numArrays,
int  defaultStatus 
)

Set the list of arrays that have entries.

For arrays that already have entries, the settings are copied. For arrays that don't already have an entry, they are assigned the given default status. If no default status is given, it is assumed to be on. There will be no more entries than the names given. This method should be called only by the filter owning this object. The signature with the default must have a different name due to a bug in the Borland C++ 5.5 compiler.

This method does not call this->Modified().

◆ CopySelections()

void vtkDataArraySelection::CopySelections ( vtkDataArraySelection selections)

Copy the selections from the given vtkDataArraySelection instance.

This method will call this->Modified() if the array selections changed.

◆ Union() [1/2]

void vtkDataArraySelection::Union ( vtkDataArraySelection other)
inline

Update this to include values from other.

For arrays that don't exist in this but exist in other, they will get added to this with the same array setting as in other. Array settings for arrays already in this are left unchanged.

This method will call this->Modified() if the array selections changed unless skipModified is set to true (default is false).

Definition at line 203 of file vtkDataArraySelection.h.

◆ Union() [2/2]

void vtkDataArraySelection::Union ( vtkDataArraySelection other,
bool  skipModified 
)

Update this to include values from other.

For arrays that don't exist in this but exist in other, they will get added to this with the same array setting as in other. Array settings for arrays already in this are left unchanged.

This method will call this->Modified() if the array selections changed unless skipModified is set to true (default is false).

◆ SetUnknownArraySetting()

virtual void vtkDataArraySelection::SetUnknownArraySetting ( int  )
virtual

Get/Set enabled state for any unknown arrays.

Default is 0 i.e. not enabled. When set to 1, ArrayIsEnabled will return 1 for any array not explicitly specified.

◆ GetUnknownArraySetting()

virtual int vtkDataArraySelection::GetUnknownArraySetting ( )
virtual

Get/Set enabled state for any unknown arrays.

Default is 0 i.e. not enabled. When set to 1, ArrayIsEnabled will return 1 for any array not explicitly specified.
