Method Details

select

public Structure select(List<String> memberNames)

Description copied from class: Structure

Create a subset of the Structure consisting only of the given member variables

Overrides:

select in class Structure

Parameters:

memberNames - list of Variable names, already a member

Returns:

Structure containing just those members

getOriginalVariable

public Variable getOriginalVariable()

A StructureDS may wrap another Structure.

Specified by:

getOriginalVariable in interface VariableEnhanced

Returns:

original Structure or null

getOriginalDataType

public DataType getOriginalDataType()

When this wraps another Variable, get the original Variable's DataType.

Returns:

original Variable's DataType

getOriginalName

public String getOriginalName()

When this wraps another Variable, get the original Variable's DataType.

Specified by:

getOriginalName in interface VariableEnhanced

Returns:

original Variable's DataType

reallyRead

public Array reallyRead(Variable client,
 CancelTask cancelTask)
                 throws IOException

Description copied from class: Variable

public by accident, do not call directly.

Specified by:

reallyRead in interface ProxyReader

Overrides:

reallyRead in class Variable

Parameters:

client - the client Variable

cancelTask - user may cancel

Returns:

Array

Throws:

IOException - on error

reallyRead

public Array reallyRead(Variable client,
 Section section,
 CancelTask cancelTask)
                 throws IOException,
InvalidRangeException

Description copied from class: Variable

public by accident, do not call directly.

Specified by:

reallyRead in interface ProxyReader

Overrides:

reallyRead in class Variable

Parameters:

client - the client Variable

section - the section of data to read.

cancelTask - user may cancel

Returns:

Array

Throws:

IOException - on error

InvalidRangeException - if section has incorrect rank or illegal shape.

getCoordinateSystems

public com.google.common.collect.ImmutableList<CoordinateSystem> getCoordinateSystems()

Description copied from interface: Enhancements

Get the list of Coordinate Systems for this Variable.

Specified by:

getCoordinateSystems in interface ucar.nc2.dataset.Enhancements

Returns:

list of type CoordinateSystem; may be empty but not null.

getDescription

public String getDescription()

Description copied from class: Variable

Get the description of the Variable. Default is to use CDM.LONG_NAME attribute value. If not exist, look for "description", "title", or "standard_name" attribute value (in that order).

Specified by:

getDescription in interface ucar.nc2.dataset.Enhancements

Specified by:

getDescription in interface VariableSimpleIF

Overrides:

getDescription in class Variable

Returns:

description, or null if not found.

getUnitsString

public String getUnitsString()

Description copied from class: Variable

Get the Unit String for the Variable. Looks for the CDM.UNITS attribute value

Specified by:

getUnitsString in interface ucar.nc2.dataset.Enhancements

Specified by:

getUnitsString in interface VariableSimpleIF

Overrides:

getUnitsString in class Variable

Returns:

unit string, or null if not found.

toBuilder

public StructureDS.Builder<?> toBuilder()

Description copied from class: Structure

Turn into a mutable Builder. Can use toBuilder().build() to copy.

Overrides:

toBuilder in class Structure

builder

public static StructureDS.Builder<?> builder()
