getFileExtensionFromMime

public String getFileExtensionFromMime(String mime)

Description copied from interface: MimeService

Gets the file extension from provided mime or null if it cannot be found in configuration properties. List of all configured mime types and corresponding file extensions can be found in advanced.properties file (look for keys starting from media.customextension).

Specified by:

getFileExtensionFromMime in interface MimeService

Parameters:

mime - the mime to check

Returns:

the file extension from mime

getBestExtensionFromMime

public String getBestExtensionFromMime(String mime)

Description copied from interface: MimeService

Gets the best matching extension from mime. This method first tries to look into configured file extensions in advanced.properties file and if cannot be found default bin file extension is returned

Specified by:

getBestExtensionFromMime in interface MimeService

Parameters:

mime - the mime to check

Returns:

the best extension from mime

getMimeFromFileExtension

public String getMimeFromFileExtension(String fileName)

Description copied from interface: MimeService

Gets the mime from file extension or null if it cannot be found in configuration properties. List of all configured mime types and corresponding file extensions can be found in advanced.properties file (look for keys starting from mediatype.by.fileextension).

Specified by:

getMimeFromFileExtension in interface MimeService

Parameters:

fileName - the file name to check

Returns:

the mime from file extension

getConfigParameter

protected String getConfigParameter(String configKey)

getBestMime

public String getBestMime(String fileName,
                          byte[] firstBytes,
                          String overrideMime)

Description copied from interface: MimeService

Gets the best mime. This method first tries to determine from fileName extension. If it cannot be determined provided firstBytes of data are used to dermine mime. If it fail then overrideMime may be used if it is on list of supported mime types (look for media.customextension keys in advanced.properties file for supported mime types and file extensions). Finally if it fail than default mime is returned which is always application/octet-stream.

Specified by:

getBestMime in interface MimeService

Parameters:

fileName - the file name to check

firstBytes - the first bytes of data

overrideMime - the override mime

Returns:

the best mime

getMimeFromFirstBytes

public String getMimeFromFirstBytes(byte[] firstBytes)

Description copied from interface: MimeService

Gets the mime from first bytes of data or null if it cannot be determined.

Specified by:

getMimeFromFirstBytes in interface MimeService

Parameters:

firstBytes - the first bytes of data

Returns:

the mime from first bytes

isZipRelatedMime
