Field Detail

WADL

public static final MediaType WADL

FAST_INFOSET

public static final MediaType FAST_INFOSET

MEDIA_TYPE_COMPARATOR

public static final java.util.Comparator<MediaType> MEDIA_TYPE_COMPARATOR
Comparator for media types.

x/y < x/* < \*\/*

MEDIA_TYPE_LIST_COMPARATOR

public static final java.util.Comparator<java.util.List<? extends MediaType>> MEDIA_TYPE_LIST_COMPARATOR
Comparator for lists of media types.

The least specific content type of each list is obtained and then compared using MEDIA_TYPE_COMPARATOR.

Assumes each list is already ordered according to MEDIA_TYPE_COMPARATOR and therefore the least specific media type is at the end of the list.

GENERAL_MEDIA_TYPE

public static final MediaType GENERAL_MEDIA_TYPE
The general media type corresponding to \*\/*.

GENERAL_MEDIA_TYPE_LIST

public static final java.util.List<MediaType> GENERAL_MEDIA_TYPE_LIST
A singleton list containing the general media type.

GENERAL_ACCEPT_MEDIA_TYPE

public static final AcceptableMediaType GENERAL_ACCEPT_MEDIA_TYPE
The general acceptable media type corresponding to \*\/*.

GENERAL_ACCEPT_MEDIA_TYPE_LIST

public static final java.util.List<AcceptableMediaType> GENERAL_ACCEPT_MEDIA_TYPE_LIST
A singleton list containing the general acceptable media type.

QUALITY_SOURCE_MEDIA_TYPE_COMPARATOR

public static final java.util.Comparator<QualitySourceMediaType> QUALITY_SOURCE_MEDIA_TYPE_COMPARATOR
Comparator for lists of quality source media types.

GENERAL_QUALITY_SOURCE_MEDIA_TYPE_LIST

public static final java.util.List<MediaType> GENERAL_QUALITY_SOURCE_MEDIA_TYPE_LIST
A singleton list containing the general media type.

Method Detail

typeEquals

public static final boolean typeEquals(MediaType m1,
                                       MediaType m2)

intersects

public static final boolean intersects(java.util.List<? extends MediaType> ml1,
                                       java.util.List<? extends MediaType> ml2)

mostSpecific

public static final MediaType mostSpecific(MediaType m1,
                                           MediaType m2)
