Method Detail

transferDataset

public static void transferDataset(NetcdfFile src,
                                   NetcdfDataset target,
                                   ReplaceVariableCheck replaceCheck)

Copy contents of "src" to "target". skip ones that already exist (by name). Dimensions and Variables are replaced with equivalent elements, but unlimited dimensions are turned into regular dimensions. Attribute doesnt have to be replaced because its immutable, so its copied by reference.

Parameters:

src - transfer from here. If src is a NetcdfDataset, transferred variables get reparented to target group.

target - transfer to this NetcdfDataset.

replaceCheck - if null, add if a Variable of the same name doesnt already exist, otherwise replace if replaceCheck.replace( Variable v) is true

transferVariableAttributes

public static void transferVariableAttributes(Variable src,
                                              Variable target)

Copy attributes from src to target, skip ones that already exist (by name)

Parameters:

src - copy from here

target - copy to here

transferGroupAttributes

public static void transferGroupAttributes(Group src,
                                           Group target)

Copy attributes from src to target, skip ones that already exist (by name)

Parameters:

src - copy from here

target - copy to here

findGroup

public static Group findGroup(NetcdfFile newFile,
                              Group oldGroup)

Find the Group in newFile that corresponds (by name) with oldGroup

Parameters:

newFile - look in this NetcdfFile

oldGroup - corresponding (by name) with oldGroup

Returns:

corresponding Group, or null if no match.

getBoundsDimension

public static Dimension getBoundsDimension(NetcdfFile ncfile)
