Class Detail

pvc.data.Datum

The Datum class represents a "row" of data in a data set.

Field Detail

{object} atoms

Gets the atoms map of the complex value. The map's keys are dimension names and the values are the corresponding Atom.

Borrowed from:: Complex

{number} id

Gets the unique, sequential identifier of the complex value.

Borrowed from:: Complex

{string} key

Gets the key of the complex.

The key is a unique string representation of complex value and is used to index complexes in dictionaries.

For datums, if the complex type has any key dimensions, as per pvc.options.DimensionType#isKey, its key is composed by the keys of the atoms of the key dimensions. Otherwise, their key is the #id.

For data sets, the key is a combination of the Atom#keys of contained #atoms.

Borrowed from:: Complex

{any} label

Gets the label of the complex.

When a complex contains a single atom, its label is the label of that atom. Otherwise, the "label" of the complex is determined by combining the the Atom#labels of contained #atoms.

Borrowed from:: Complex

{pvc.data.Data} owner

The owner data set of the complex value. The owner data set is the root data set that holds the whole extent of datums.

Borrowed from:: Complex

{any} value

Gets the value of the complex.

When a complex contains a single atom, its value will be the typed value of that atom. Otherwise, the "value" of a complex is its #key.

Borrowed from:: Complex

{boolean} isSelected

Gets a value that indicates if the datum is in a selected state.

{boolean} isVisible

Gets a value that indicates if the datum is in a visible state.

{string} interpDimName

Gets the name of the interpolated dimension of this datum.

{pvc.options.varia.NullInterpolationMode} interpolation

Gets the type of interpolation that generated this datum.

{boolean} isInterpolated

Gets a value that indicates if the datum was generated by an interpolation operation and is not part of the data source.

See:: #interpolation

{boolean} isNull

Gets a value that indicates if the datum considered to be null. A datum is considered null if the atoms of all of its dimensions that are considered "measures" have a null value.

{boolean} isTrend

Gets a value that indicates if the datum was generated by a trending operation and is not part of the data source.

See:: #trend

{boolean} isVirtual

Gets a value that indicates if the datum was generated by an interpolation or trending operation and is not part of the data source.

See:: #isTrend; #isInterpolated

{pvc.options.varia.PlotTrending} trend

Gets information about the trending operation that generated this datum.

See:: #isTrend
