MimeRegistry

public static final MimeRegistry MimeRegistry

Constructor Detail

MimeType

protected MimeType(java.lang.String name,
        FileType category)

A mime type name must have the form <media type> "/" <subtype>.

Parameters:

name - a valid mime type name

category - parent type

Method Detail

getMediaType

public java.lang.String getMediaType()

Returns the first part of the mime type name, the media type.

Returns:

media type

getSubType

public java.lang.String getSubType()

Returns the second part of the mime type name, the subtype.

Returns:

subtype

setExtensions

public void setExtensions(java.util.List<java.lang.String> extensionList)

Sets the extension for this mime type.

Parameters:

extensionList - extensions to be used

addExtension

public void addExtension(java.lang.String fileExtension)

Adds an entry to the list of associated file extensions. File extensions should be specified with a leading dot, but a plain extension is accepted also.

Parameters:

fileExtension - with, or without leading dot.

removeExtension

public void removeExtension(java.lang.String fileExtension)

Removes a previously associated file extension. File extensions should be specified with a leading dot, but a plain extension is accepted also.

Parameters:

fileExtension - with, or without leading dot.

listFileExtensions

public java.util.List<java.lang.String> listFileExtensions()

Returns the list of file extensions associated with this mime type. File extensions are returned with leading dot.

Returns:

list of associated file extensions, possibly empty.

matchExtension

public boolean matchExtension(java.lang.String fileExtension)

Returns true if the specified file extension is in the list of extensions associated with this mime type. File extensions should be specified with a leading dot, but a plain extension is accepted also.

Parameters:

fileExtension - with, or without leading dot.

Returns:

true if extension is associated with this mime type

isValidMimeIdentifier

public static boolean isValidMimeIdentifier(java.lang.String mime)

Returns true if the specified mime type name is valid, i.e. if it matches the pattern "[a-z]+/[[a-z][0-9]\\-\\.\\+]+".

Parameters:

mime - to be tested

Returns:

true if valid mime type name

numberOfMimeTypes
