Method Detail

getMIMEType

public static String getMIMEType(String pFileExt)

Returns the default MIME type for the given file extension.

Parameters:

pFileExt - the file extension

Returns:

a String containing the MIME type, or null if there are no known MIME types for the given file extension.

getMIMETypes

public static List<String> getMIMETypes(String pFileExt)

Returns all MIME types for the given file extension.

Parameters:

pFileExt - the file extension

Returns:

a List of Strings containing the MIME types, or an empty list, if there are no known MIME types for the given file extension.

getMIMETypeMappings

public static Map<String,List<String>> getMIMETypeMappings()

Returns an unmodifiabale Map view of the extension to MIME mapping, to use as the default mapping in client applications.

Returns:

an unmodifiabale Map view of the extension to MIME mapping.

getExtension

public static String getExtension(String pMIME)

Returns the default file extension for the given MIME type. Specifying a wildcard type will return null.

Parameters:

pMIME - the MIME type

Returns:

a String containing the file extension, or null if there are no known file extensions for the given MIME type.

getExtensions

public static List<String> getExtensions(String pMIME)

Returns all file extension for the given MIME type. The default extension will be the first in the list. Note that no specific order is given for wildcard types (image/*, */* etc).

Parameters:

pMIME - the MIME type

Returns:

a List of Strings containing the MIME types, or an empty list, if there are no known file extensions for the given MIME type.

getExtensionMappings

public static Map<String,List<String>> getExtensionMappings()

Returns an unmodifiabale Map view of the MIME to extension mapping, to use as the default mapping in client applications.

Returns:

an unmodifiabale Map view of the MIME to extension mapping.

bareMIME

public static String bareMIME(String pMIME)

Removes any charset or extra info from the mime-type string (anything after a semicolon, ;, inclusive).

Parameters:

pMIME - the mime-type string

Returns:

the bare mime-type

main

public static void main(String[] pArgs)

For debugging. Prints all known MIME types and file extensions.

Parameters:

pArgs - command line arguments
