Method Detail

findNetcdfFormatType

public static NetcdfFileFormat findNetcdfFormatType(RandomAccessFile raf)
                                             throws IOException

Figure out what kind of netcdf-related file we have. Constraint: leave raf read pointer to point just after the magic number.

Parameters:

raf - to test type

Returns:

NetcdfFileFormat that matches constants in netcdf-c/include/netcdf.h, or INVALID if not a netcdf file.

Throws:

IOException

formatName

public String formatName()

isExtendedModel

public boolean isExtendedModel()

isNetdf3format

public boolean isNetdf3format()

isNetdf4format

public boolean isNetdf4format()

isValidNetcdfObjectName

public static boolean isValidNetcdfObjectName(String name)

Determine if the given name can be used for a NetCDF object, i.e. a Dimension, Attribute, or Variable. The allowed name syntax (in RE form) is:

 ([a-zA-Z0-9_]|{UTF8})([^\x00-\x1F\x7F/]|{UTF8})*
 

where UTF8 represents a multi-byte UTF-8 encoding. Also, no trailing spaces are permitted in names. We do not allow '/' because HDF5 does not permit slashes in names as slash is used as a group separator. If UTF-8 is supported, then a multi-byte UTF-8 character can occur anywhere within an identifier.

Parameters:

name - the name to validate.

Returns:

true if the name is valid.

makeValidNetcdfObjectName

public static String makeValidNetcdfObjectName(String name)

Convert a name to a legal netcdf-3 name.

Parameters:

name - the name to convert.

Returns:

the converted name.

isValidNetcdfObjectName(String)

memequal

public static boolean memequal(byte[] b1,
                               byte[] b2,
                               int len)

valueOf

public static NetcdfFileFormat valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

values

public static NetcdfFileFormat[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (NetcdfFileFormat c : NetcdfFileFormat.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

version

public int version()
