Method Detail

setLibraryNameAndPath

public static void setLibraryNameAndPath(@Nullable
                                         java.lang.String jna_path,
                                         @Nullable
                                         java.lang.String lib_name)

Set the path and name of the netcdf c library. Must be called before load() is called.

Parameters:

jna_path - path to shared libraries, may be null. If null, will look for system property "jna.library.path", then environment variable "JNA_PATH". If set, will set the environment variable "JNA_PATH".

lib_name - library name, may be null. If null, will use "netcdf".

isLibraryPresent

public static boolean isLibraryPresent()

Test if the netcdf C library is present and loaded

Returns:

true if present

getForeignFunctionInterface

public static Nc4prototypes getForeignFunctionInterface()

Get the interface to the Nectdf C library.

getVersion

@Nullable
public static java.lang.String getVersion()

Get the version of the loaded Nectdf C library. Call isClibraryPresent() first.

setLogLevel

public static int setLogLevel(int level)

Set the log level for Netcdf C library. This calls the Netcdf C library nc_set_log_level() method. If the system property "jna.library.loglevel" is set, that is the default, this method overrides it.

Returns:

the previous level, as returned from nc_set_log_level().
