Method Detail

isValidNASA

public static boolean isValidNASA(java.lang.String varName)

Determine if the input variable name is a valid NASA product

Parameters:

varName - Variable name to validate.

Returns:

true if varName passes checks.

isValidSet

public static boolean isValidSet(java.util.List fileList)

Determine if the set if filenames constitutes contiguous SNPP granules of the same geographic coverage.

Parameters:

fileList - List of files to validate.

Returns:

true if fileList passes checks.

replaceLast

public static java.lang.String replaceLast(java.lang.String string,
                                           java.lang.String substring,
                                           java.lang.String replacestr)

Replace last substring within input string which matches the input with the provided replacement string.

Parameters:

string -

substring -

replacestr -

Returns:

hasCommonGeo

public static boolean hasCommonGeo(java.util.List fileList,
                                   java.io.File directory)

Determine if a set if filenames which constitutes contiguous SNPP granules of various products all share the same geolocation data type.

Parameters:

fileList - List of files to validate.

directory - Used when "GEO" is not embedded within one of fileList.

Returns:

true if fileList passes checks.
