NetcdfFile (cdm-core 5.3.2 API)

java.lang.Object
- ucar.nc2.NetcdfFile

All Implemented Interfaces:: Closeable, AutoCloseable, FileCacheable

Direct Known Subclasses:: CdmRemote, NetcdfDataset, NetcdfFileSubclass

public class NetcdfFile
extends Object
implements FileCacheable, Closeable

Read-only scientific datasets that are accessible through the netCDF API. Immutable after setImmutable() is called. Reading data is not thread-safe because of the use of RandomAccessFile.

Using this class's Builder scheme to create a NetcdfFile object could, for example, be accomplished as follows, using a try/finally block to ensure that the NetcdfFile is closed when done.

 NetcdfFile ncfile = null;
 try {
   ncfile = NetcdfFile.builder().setLocation(fileName).build();
   // do stuff
 } finally {
   if (ncfile != null) {
     ncfile.close();
   }
 }

More conveniently, a NetcdfFile object may be created using one of the static methods in NetcdfFiles:

 NetcdfFile ncfile = null;
 try {
   ncfile = NetcdfFiles.open(fileName);
   // do stuff
 } finally {
   if (ncfile != null) {
     ncfile.close();
   }
 }
 
 Or better yet, use try-with-resources:
 

  try (NetcdfFile ncfile = NetcdfFiles.open(fileName)) {
   // do stuff
 }
 

 Naming
 Each object has a name (aka "full name") that is unique within the entire netcdf file, and
 a "short name" that is unique within the parent group.
 These coincide for objects in the root group, and so are backwards compatible with version
 3 files.
 
 Variable: group1/group2/varname
 
Structure member Variable: group1/group2/varname.s1.s2
 
Group Attribute: group1/group2@attName
 
Variable Attribute: group1/group2/varName@attName

    Open an existing file (read only), with option of cancelling, setting the RandomAccessFile buffer size for efficiency, with an optional special object for the iosp.
    Parameters:
    location - location of file. This may be a
    
    local netcdf-3 filename (with a file: prefix or no prefix)
    remote netcdf-3 filename (with an http: prefix)

It will look for the uncompressed file before it does any of that. Generally it prefers to place the uncompressed file in the same directory as the original file. If it does not have write permission on that directory, it will use the directory defined by ucar.nc2.util.DiskCache class.
    buffer_size - RandomAccessFile buffer size, if <= 0, use default size

  - findVariable
```
@Nullable
public Variable findVariable(String fullNameEscaped)
```
    Find a Variable, with the specified (escaped full) name. It may possibly be nested in multiple groups and/or structures. An embedded "." is interpreted as structure.member. An embedded "/" is interpreted as group/variable. If the name actually has a ".", you must escape it (call NetcdfFiles.makeValidPathName(varname)) Any other chars may also be escaped, as they are removed before testing.
    
    Parameters:
    
    fullNameEscaped - eg "/group/subgroup/name1.name2.name".

    Look in the given Group and in its nested Groups for a Variable with a String valued Attribute with the given name and value.
    
    Parameters:
    
    g - start with this Group, null for the root Group.
    
    attName - look for an Attribuite with this name.
    
    attValue - look for an Attribuite with this value.

    the first Variable that matches, or null if none match.
  - findDimension
```
@Nullable
public Dimension findDimension(String fullName)
```
    Finds a Dimension with the specified full name. It may be nested in multiple groups. An embedded "/" is interpreted as a group separator. A leading slash indicates the root group. That slash may be omitted, but the fullName will be treated as if it were there. In other words, the first name token in fullName is treated as the short name of a Group or Dimension, relative to the root group.
    
    Parameters:
    
    fullName - Dimension full name, e.g. "/group/subgroup/dim".
    
    Returns:
    
    the Dimension or null if it wasn't found.

    Returns:
    
    the unlimited Dimension, or null if none.
  - getDimensions
```
public List<Dimension> getDimensions()
```
    Get the shared Dimensions used in this file. This is part of "version 3 compatibility" interface.
    If the dimensions are in a group, the dimension name will have the group name, in order to disambiguate the dimensions. This means that a Variable's dimensions will not match Dimensions in this list. Therefore it is better to get the shared Dimensions directly from the Groups.
    
    Returns:
    
    List of type Dimension.
  - getVariables
```
public List<Variable> getVariables()

  - findAttribute
```
@Nullable
public Attribute findAttribute(String fullNameEscaped)
```
    Find an attribute, with the specified (escaped full) name. It may possibly be nested in multiple groups and/or structures. An embedded "." is interpreted as structure.member. An embedded "/" is interpreted as group/group or group/variable. An embedded "@" is interpreted as variable@attribute If the name actually has a ".", you must escape it (call NetcdfFiles.makeValidPathName(varname)) Any other chars may also be escaped, as they are removed before testing.
    
    Parameters:
    
    fullNameEscaped - eg "@attName", "/group/subgroup/@attName" or "/group/subgroup/varname.name2.name@attName"
