Detailed Description

Member Function Documentation

add()

virtual void inviwo::Column::add ( std::string_view value )

pure virtual

Implemented in inviwo::TemplateColumn< T >, inviwo::TemplateColumn< std::uint32_t >, and inviwo::TemplateColumn< uint32_t >.

append()

virtual void inviwo::Column::append ( const Column & col )

pure virtual

Appends all rows from column col

Parameters

col

Implemented in inviwo::CategoricalColumn, inviwo::TemplateColumn< T >, inviwo::TemplateColumn< std::uint32_t >, and inviwo::TemplateColumn< uint32_t >.

getAsDouble()

virtual double inviwo::Column::getAsDouble ( size_t idx ) const

pure virtual

Implemented in inviwo::CategoricalColumn.

getAsString()

virtual std::string inviwo::Column::getAsString ( size_t idx ) const

pure virtual

Implemented in inviwo::CategoricalColumn.

getBuffer() [1/2]

virtual std::shared_ptr< const BufferBase > inviwo::Column::getBuffer ( ) const

pure virtual

Implemented in inviwo::CategoricalColumn.

getBuffer() [2/2]

virtual std::shared_ptr< BufferBase > inviwo::Column::getBuffer ( )

pure virtual

Implemented in inviwo::CategoricalColumn.

getCustomRange()

virtual std::optional< dvec2 > inviwo::Column::getCustomRange ( ) const

pure virtual

Returns the custom column range. If no range has been set previously, the return value will be std::nullopt.

Implemented in inviwo::CategoricalColumn, inviwo::TemplateColumn< T >, inviwo::TemplateColumn< std::uint32_t >, and inviwo::TemplateColumn< uint32_t >.

getDataRange()

virtual dvec2 inviwo::Column::getDataRange ( ) const

pure virtual

Returns the range (i.e. the min/max) of the data, ignoring any custom range

Implemented in inviwo::CategoricalColumn, inviwo::TemplateColumn< T >, inviwo::TemplateColumn< std::uint32_t >, and inviwo::TemplateColumn< uint32_t >.

getRange()

virtual dvec2 inviwo::Column::getRange ( ) const

pure virtual

Returns the custom range if set or else the range (i.e. the min/max) of the data

Implemented in inviwo::CategoricalColumn, inviwo::TemplateColumn< T >, inviwo::TemplateColumn< std::uint32_t >, and inviwo::TemplateColumn< uint32_t >.

setCustomRange()

virtual void inviwo::Column::setCustomRange ( std::optional< dvec2 > )

pure virtual

Set a custom range for the column which can be used for normalization, plotting, color mapping, etc.

Implemented in inviwo::CategoricalColumn, inviwo::TemplateColumn< T >, inviwo::TemplateColumn< std::uint32_t >, and inviwo::TemplateColumn< uint32_t >.
