Class MediaType
public final class MediaType extends Object
*
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 Details
-
type
Returns the top-level media type. For example,"text"
in"text/plain"
. -
subtype
Returns the media subtype. For example,"plain"
in"text/plain"
. -
parameters
Returns a multimap containing the parameters of this media type. -
charset
Returns aCharset
for the value of the charset parameter if it is specified.- Returns:
- the
Charset
, ornull
if the charset parameter is not 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
-
charset
Returns aCharset
for the value of the charset parameter if it is specified.- Returns:
- the
Charset
, ordefaultCharset
if the charset parameter is not 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
Returns a new instance with the same type and subtype as this instance, but without any parameters. -
withParameters
Replaces all parameters with the given parameters.- Throws:
IllegalArgumentException
- if any parameter or value is invalid
-
withParameters
Replaces all parameters with the given attribute with parameters using the given values. If there are no values, any existing parameters with the given attribute are removed.- Throws:
IllegalArgumentException
- if eitherattribute
orvalues
is invalid
-
withParameter
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(String, Iterable)
. PreferwithCharset(java.nio.charset.Charset)
for setting thecharset
parameter when using aCharset
object.- Throws:
IllegalArgumentException
- if eitherattribute
orvalue
is invalid
-
withCharset
Returns a new instance with the same type and subtype as this instance, with thecharset
parameter set to the name 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()Returnstrue
if either the type or subtype is the wildcard. -
numWildcards
public int numWildcards()Returns the number of wildcards of thisMediaType
. -
is
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"
. -
belongsTo
Returnstrue
if thisMediaType
belongs to the givenMediaType
. Similar to whatis(MediaType)
does except that this one compares the parameters case-insensitively and excludes 'q' parameter. -
qualityFactor
public float qualityFactor(float defaultValueIfNotSpecified)Returns the quality factor of thisMediaType
. If it is not specified,defaultValueIfNotSpecified
will be returned. -
qualityFactor
public float qualityFactor()Returns the quality factor of thisMediaType
. If it is not specified,1.0f
will be returned. -
nameWithoutParameters
Returns a name of thisMediaType
only consisting of the type and the sub type. -
create
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
Parses a media type from its string representation.- Throws:
IllegalArgumentException
- if the input is not parsable
-
equals
-
hashCode
public int hashCode() -
toString
Returns the string representation of this media type in the format described in RFC 2045.
