@Beta @GwtCompatible @Immutable public final class MediaType extends Object
Represents an Internet Media Type (also known as a MIME Type or Content Type). This class also supports the concept of media ranges defined by HTTP/1.1. As such, the*
character is treated as a wildcard and is used to represent any acceptable type or subtype value. A media type may not have wildcard type with a declared subtype. The*
character has no special meaning as part of a parameter. All values for type, subtype, parameter attributes or parameter values must be valid according to RFCs 2045 and 2046.All portions of the media type that are case-insensitive (type, subtype, parameter attributes) are normalized to lowercase. The value of the
charset
parameter is normalized to lowercase, but all others are left as-is.Note that this specifically does not represent the value of the MIME
Content-Type
header and as such has no support for header-specific considerations such as line folding and comments.For media types that take a charset the predefined constants default to UTF-8 and have a "_UTF_8" suffix. To get a version without a character set, use
withoutParameters()

Method Detail
-
type
public String type()
Returns the top-level media type. For example,"text"
in"text/plain"
.
-
subtype
public String subtype()
Returns the media subtype. For example,"plain"
in"text/plain"
.
-
parameters
public ImmutableListMultimap<String,String> parameters()
Returns a multimap containing the parameters of this media type.
-
charset
public Optional<Charset> charset()
Returns an optional charset for the value of the charset parameter if it is specified.- Throws:
IllegalStateException
- if multiple charset values have been set for this media typeIllegalCharsetNameException
- if a charset value is present, but illegalUnsupportedCharsetException
- if a charset value is present, but no support is available in this instance of the Java virtual machine
-
withoutParameters
public MediaType withoutParameters()
Returns a new instance with the same type and subtype as this instance, but without any parameters.
-
withParameters
public MediaType withParameters(Multimap<String,String> parameters)
Replaces all parameters with the given parameters.- Throws:
IllegalArgumentException
- if any parameter or value is invalid
-
withParameter
public MediaType withParameter(String attribute, String value)
Replaces all parameters with the given attribute with a single parameter with the given value. If multiple parameters with the same attributes are necessary usewithParameters(com.google.common.collect.Multimap<java.lang.String, java.lang.String>)
. PreferwithCharset(java.nio.charset.Charset)
for setting thecharset
parameter when using aCharset
object.- Throws:
IllegalArgumentException
- if eitherattribute
orvalue
is invalid
-
withCharset
public MediaType withCharset(Charset charset)
Returns a new instance with the same type and subtype as this instance, with thecharset
parameter set to thename
of the given charset. Only onecharset
parameter will be present on the new instance regardless of the number set on this one.If a charset must be specified that is not supported on this JVM (and thus is not representable as a
Charset
instance, usewithParameter(java.lang.String, java.lang.String)
.
-
hasWildcard
public boolean hasWildcard()
Returns true if either the type or subtype is the wildcard.
-
is
public boolean is(MediaType mediaTypeRange)
Returnstrue
if this instance falls within the range (as defined by the HTTP Accept header) given by the argument according to three criteria:- The type of the argument is the wildcard or equal to the type of this instance.
- The subtype of the argument is the wildcard or equal to the subtype of this instance.
- All of the parameters present in the argument are present in this instance.
For example:
PLAIN_TEXT_UTF_8.is(PLAIN_TEXT_UTF_8) // true PLAIN_TEXT_UTF_8.is(HTML_UTF_8) // false PLAIN_TEXT_UTF_8.is(ANY_TYPE) // true PLAIN_TEXT_UTF_8.is(ANY_TEXT_TYPE) // true PLAIN_TEXT_UTF_8.is(ANY_IMAGE_TYPE) // false PLAIN_TEXT_UTF_8.is(ANY_TEXT_TYPE.withCharset(UTF_8)) // true PLAIN_TEXT_UTF_8.withoutParameters().is(ANY_TEXT_TYPE.withCharset(UTF_8)) // false PLAIN_TEXT_UTF_8.is(ANY_TEXT_TYPE.withCharset(UTF_16)) // false
Note that while it is possible to have the same parameter declared multiple times within a media type this method does not consider the number of occurrences of a parameter. For example,
"text/plain; charset=UTF-8"
satisfies"text/plain; charset=UTF-8; charset=UTF-8"
.
-
create
public static MediaType create(String type, String subtype)
Creates a new media type with the given type and subtype.- Throws:
IllegalArgumentException
- if type or subtype is invalid or if a wildcard is used for the type, but not the subtype.
-
parse
public static MediaType parse(String input)
Parses a media type from its string representation.- Throws:
IllegalArgumentException
- if the input is not parsable
-
