org.das2.dataset.DataSet

General interface for objects encapsulating a data set


PROPERTY_CACHE_TAG

CacheTag object describing the start, end, and resolution of the dataset.


PROPERTY_X_CACHE_RNG

DatumRange describing the range of a dataset in the X dimension


PROPERTY_X_CACHE_RES

Datum providing the resolution in the X dimension


PROPERTY_Y_CACHE_RNG

DatumRange describing the range of a dataset in the X dimension


PROPERTY_Y_CACHE_RES

Datum providing the resolution in the X dimension


PROPERTY_SIZE_BYTES

Long estimating the size of the dataset in memory. For example, if a dataset is backed by a local file, then zero for this indicates no penalty for storing this dataset.


PROPERTY_X_TAG_WIDTH

Datum which is the nominal distance between successive xTags. This is used for example to prevent interpolation between distant measurements


PROPERTY_Y_TAG_WIDTH

Datum, see xTagWidth


PROPERTY_X_RANGE

DatumRange useful for setting scales


PROPERTY_X_VALID_MIN

Double, used to indicate minimum valid X value


PROPERTY_X_VALID_MAX

Double, used to indicate maximum valid X value


PROPERTY_Y_RANGE

Datum, useful for setting scales


PROPERTY_Y_VALID_MIN

Double, used to indicate minimum valid X value


PROPERTY_Y_VALID_MAX

Double, used to indicate maximum valid X value


PROPERTY_Z_RANGE

DatumRange useful for setting scales


PROPERTY_Z_VALID_MIN

Double, used to indicate minimum valid X value


PROPERTY_Z_VALID_MAX

Double, used to indicate maximum valid X value


PROPERTY_Y_FILL

Double: Raw value used to indicate fill data.


PROPERTY_Z_FILL

Raw value used to indicate fill data. Since yscan's are rectangular it's handy to have a fill value to indicate gaps in the rectangle


PROPERTY_RENDERER

suggest render method to use. These are canonical: spectrogram symbolLine stackedHistogram


PROPERTY_Y_SCALETYPE

String "log" or "linear"


PROPERTY_Z_SCALETYPE

String "log" or "linear"


PROPERTY_X_LABEL


PROPERTY_Y_LABEL


PROPERTY_Z_LABEL


PROPERTY_X_SUMMARY

A brief description of the x direction values


PROPERTY_Y_SUMMARY

A brief description of the y direction values


PROPERTY_Z_SUMMARY

A brief description of the z direction values


PROPERTY_SUMMARY

A brief description for the entire stream


PROPERTY_X_FORMAT

The format for printing X, Y and Z items, see the Das 2.2.2 (or higher) ICD for a list of valid foramt strings


PROPERTY_Y_FORMAT


PROPERTY_Z_FORMAT


PROPERTY_TITLE

finally, this data model is done with the addition of title.


PROPERTY_X_MONOTONIC

Boolean assuring that the dataset is monotonic in X. This allows some optimizations to be made.


PROPERTY_Y_MONOTONIC

Boolean assuring that the dataset is monotonic in Y. This allows some optimizations to be made.


PROPERTY_PLANE_PEAKS

dataset containing the peaks when available


PROPERTY_SOURCE

Indicator that dataset is not intrinsic but was derived from some other dataset


PROPERTY_OPERATION

Indicator of which operation was performed on the input source


PROPERTY_PLANE_WEIGHTS

dataset containing the weights when available


PROPERTY_FORMATTER

DatumFormatter for formatting data in the dataset.


getPlanarView

getPlanarView( String planeID ) → org.das2.dataset.DataSet

Returns a DataSet with the specified view as the primary view.

Parameters

planeID - the String id of the requested plane.

Returns:

the specified view, as a DataSet
