Method Detail

getCharset

public static java.lang.String getCharset(java.lang.String mediatype)

isMatch

public static boolean isMatch(java.lang.String a,
                              java.lang.String b)

Returns true if media type a matches media type b

isMatch

public static boolean isMatch(javax.activation.MimeType a,
                              javax.activation.MimeType b)

isMatch

public static boolean isMatch(javax.activation.MimeType a,
                              javax.activation.MimeType b,
                              boolean includeparams)

Returns true if media type a matches media type b

isApp

public static boolean isApp(java.lang.String a)

Returns true if media type a matches application/atomsrv+xml

isAtom

public static boolean isAtom(java.lang.String a)

Returns true if media type a matches application/atom+xml

isEntry

public static boolean isEntry(java.lang.String a)

Returns true if media type a specifically identifies an Atom entry document

isFeed

public static boolean isFeed(java.lang.String a)

Returns true if media type a explicitly identifies an Atom feed document

isXml

public static boolean isXml(java.lang.String a)

Returns true if media type a matches application/xml, text/xml or application/*+xml

isText

public static boolean isText(java.lang.String a)

Returns true if media type a matches text/*

isMimeType

public static boolean isMimeType(java.lang.String a)

Returns true if this is a valid media type

getMimeType

public static <T extends Base> java.lang.String getMimeType(T base)

Returns the appropriate media type for the given Abdera base

condense

public static java.lang.String[] condense(java.lang.String... types)

This will take an array of media types and will condense them based on wildcards, etc. For instance, condense("image/png", "image/jpg", "image/*") condenses to [image/*] condense("application/atom", "application/*", "image/png", "image/*") condenses to [application/*, image/*]

getComparator

public static java.util.Comparator<java.lang.String> getComparator()

Returns a Comparator that can be used to compare and sort MIME media types according to their level of specificity (e.g. text/* is less specific than text/plain and would appear first in a sorted list)

compare

public static int compare(javax.activation.MimeType mt1,
                          javax.activation.MimeType mt2)

Compare two media types according to their relative level of specificity

compare

public static int compare(java.lang.String t1,
                          java.lang.String t2)

Compare two media types according to their relative level of specificity

isMultipart

public static boolean isMultipart(java.lang.String a)

Returns true if media type is a multiparted file.
