Interface Netcdf

All Known Implementing Classes:

AbstractNetcdf, NetcdfFile, NetcdfWrapper, RemoteNetcdf, VisADAdapter

public interface Netcdf

This is the interface for Netcdf objects. A Netcdf is seen as a set of Variables, the DimensionSet which is the union of the Dimensions used by the Variables, and any global Attributes. The Variable interface has data i/o (get/set) functionality.

This set, the associated DimensionSet and AttributeSet are immutable.

The portions of this interface which do not have to do with i/o capable Variables are available in Schema.

Method Summary

boolean	contains(java.lang.Object oo) Tests if the argument is in this set.
boolean	contains(java.lang.String name) Tests if the Variable identified by name is in this set.
Variable	get(java.lang.String name) Retrieve the variable associated with the specified name.
Attribute	getAttribute(java.lang.String name) Convenience function; look up global Attribute by name.
AttributeSet	getAttributes() Returns the set of attributes associated with this, also know as the "global" attributes.
DimensionSet	getDimensions() Returns the set of dimensions associated with this, the union of those used by each of the variables.
VariableIterator	iterator() Returns VariableIterator for the elements.
int	size() Returns the number of variables

Parameters:

name - String which identifies the desired variable

Returns:

the variable, or null if not found

contains

boolean contains(java.lang.String name)

Tests if the Variable identified by name is in this set.

Parameters:

name - String which identifies the desired variable

Returns:

true if and only if this set contains the named variable.

contains

boolean contains(java.lang.Object oo)

Tests if the argument is in this set.

Parameters:

oo - some Object

Returns:

true if and only if this set contains oo

getDimensions

DimensionSet getDimensions()

Returns the set of dimensions associated with this, the union of those used by each of the variables.

Returns:

DimensionSet containing dimensions used by any of the variables. May be empty. Won't be null.

getAttributes

AttributeSet getAttributes()

Returns the set of attributes associated with this, also know as the "global" attributes.

Returns:

AttributeSet. May be empty. Won't be null.

getAttribute

Attribute getAttribute(java.lang.String name)

Convenience function; look up global Attribute by name.

Parameters:

name - the name of the attribute

Returns:

the attribute, or null if not found
