Variable (NetCDF-Java All API v5.7.0)

java.lang.Object
- ucar.nc2.CDMNode
- - ucar.nc2.Variable

All Implemented Interfaces:

java.lang.Comparable<VariableSimpleIF>, java.lang.Iterable<Attribute>, AttributeContainer, ProxyReader, VariableSimpleIF

Direct Known Subclasses:

DODSVariable, Structure, VariableDS
```
public class Variable
extends CDMNode
implements VariableSimpleIF, ProxyReader, AttributeContainer
```
A Variable is a logical container for data. It has a dataType, a set of Dimensions that define its array shape, and optionally a set of Attributes.
The data is a multidimensional array of primitive types, Strings, or Structures. Data access is done through the read() methods, which return a memory resident Array.
Immutable if setImmutable() was called. TODO Variable will be immutable in 6. TODO Variable will not implement AttributeContainer in 6, use Variable.attributes(). TODO Variable will not extend CDMNode in 6.

```
    Read a section of the data for this Variable and return a memory resident Array. The Array has the same element type as the Variable, and the requested shape. Note that this does not do rank reduction, so the returned Array has the same rank as the Variable. Use Array.reduce() for rank reduction.
    assert(origin[ii] + shape[ii]*stride[ii] <= Variable.shape[ii]);
    
    Parameters:
    
    origin - int array specifying the starting index. If null, assume all zeroes.
    
    shape - int array specifying the extents in each dimension. This becomes the shape of the returned Array.
    
    Returns:

    Parameters:
    
    sectionSpec - specification string, eg "1:2,10,:,1:100:10". May optionally have ().

    Read a section of the data for this Variable from the netcdf file and return a memory resident Array.
    
    Parameters:
    
    ranges - list of Range specifying the section of data to read.
    
    Returns:
    
    the requested data in a memory-resident Array
    
    Throws:

public Array read(Section section)
           throws java.io.IOException,
                  InvalidRangeException
```
    Read a section of the data for this Variable from the netcdf file and return a memory resident Array. The Array has the same element type as the Variable, and the requested shape. Note that this does not do rank reduction, so the returned Array has the same rank as the Variable. Use Array.reduce() for rank reduction.
    If the Variable is a member of an array of Structures, this returns only the variable's data in the first Structure, so that the Array shape is the same as the Variable. To read the data in all structures, use ncfile.readSectionSpec().
    Note this only allows you to specify a subset of this variable. If the variable is nested in an array of structures and you want to subset that, use NetcdfFile.read(String sectionSpec, boolean flatten);
    
    Parameters:
    
    section - list of Range specifying the section of data to read. Must be null or same rank as variable. If list is null, assume all data. Each Range corresponds to a Dimension. If the Range object is null, it means use the entire dimension.
    
    Returns:
    
    the requested data in a memory-resident Array
    
    Throws:
    
    java.io.IOException - if error
    
    InvalidRangeException - if section is invalid
  - read
```
public Array read()
           throws java.io.IOException

    Read all the data for this Variable and return a memory resident Array. The Array has the same element type and shape as the Variable.
    If the Variable is a member of an array of Structures, this returns only the variable's data in the first Structure, so that the Array shape is the same as the Variable. To read the data in all structures, use ncfile.readSection().
    
    Returns:

public void setDimensions(java.util.List<Dimension> dims)
```
    Deprecated. Use Variable.builder()
