Member Function Documentation

◆ adjustOids()

void te::qt::widgets::Histogram::adjustOids	(	te::dt::AbstractData *	interval,
		std::vector< te::da::ObjectId *>	valuesOIds
	)

It will populate the IntervalToObjectIdSet with the given interval and it's matching objectIds.

Parameters

interval	The interval that contains the given objectIds.
valuesOIds	The vector containing the ObjectIds related to the given interval

◆ clear()

void te::qt::widgets::Histogram::clear ( )

A function used to clear the contents of the histogram, deleting the pointers contained by the boost containers used to store the histogram's data.

◆ find() [1/3]

te::da::ObjectIdSet* te::qt::widgets::Histogram::find ( te::dt::AbstractData * interval )

It returns an ObjectIdSet containing all the object Ids associeted with the given interval.

Parameters

interval The interval that will be searched.

Note: it can return an empty ObjectIdSet if none ObjectIds were found. (f.e. if the user clicks on an empty area of the chart); The caller will take ownership of the returned pointer

◆ find() [2/3]

te::da::ObjectIdSet* te::qt::widgets::Histogram::find ( std::vector< te::dt::AbstractData *> intervals )

It returns an ObjectIdSet containing all the object Ids associeted with the given interval list.

Parameters

intervals A vector containing all the intervals within the selection box

Returns: An ObjectIdSet containing all the selected object Ids

Note: The caller will take ownership of the returned pointer; It will take ownership of the given pointers

◆ find() [3/3]

const te::dt::AbstractData* te::qt::widgets::Histogram::find ( const te::da::ObjectId * oid )

It returns an AbstractData representing the interval that contains the given ObjectId.

Parameters

oid	The ObjectId that will be searched.

Note: Returns NULL if no matching interval was found

◆ getInterval()

double& te::qt::widgets::Histogram::getInterval ( )

It returns the histogram's interval. Will be invalid if the histogram was created based on string intervals.

Returns: The histogram's interval.

◆ getMinValue()

double& te::qt::widgets::Histogram::getMinValue ( )

It returns the histogram's minimum value. Will be invalid if the histogram was created based on string intervals.

Returns: The histogram's minimum value.

◆ getStringInterval()

std::set<std::string>& te::qt::widgets::Histogram::getStringInterval ( )

It returns the histogram's string set of intervals. Will be invalid if the histogram was created based on numeric (double, float, etc) intervals.

Returns: The histogram's interval.

◆ getStringValues()

std::map<std::string, unsigned int> te::qt::widgets::Histogram::getStringValues ( )

It returns the map containing the histogram String values. The key is a unique string that represents an interval and the unsigned int is the frequency of that interval.

Returns: A map containing the histogram values.

◆ getType()

int& te::qt::widgets::Histogram::getType ( )

It returns the histogram's type.

Returns: An int that represents the histogram's type.

◆ getValues()

std::map<double, unsigned int> te::qt::widgets::Histogram::getValues ( )

It returns the map containing the histogram values. The key is the minimum values of the histogram's interval, and the unsigned int is the frequency of that interval.

Returns: A map containing the histogram values.

◆ insert() [1/4]

void te::qt::widgets::Histogram::insert	(	std::pair< te::dt::AbstractData *, unsigned int >	new_value,
		std::vector< te::da::ObjectId *>	valuesOIds
	)

It adds a new value to the map containing the histogram values.

Parameters

new_value	The value that will be added. The AbstractData represents the interval and the unsigned int represents that interval's frequency.
valuesOIds	A vector containing all the ObjectIds contained by the interval

Note: It will take the ownwership of the given pointers

◆ insert() [2/4]
