Constructor Detail

MediaType

public MediaType(java.lang.String type,
                 java.lang.String subtype,
                 java.util.Map<java.lang.String,java.lang.String> parameters)
Creates a new instance of MediaType with the supplied type, subtype and parameters.

Parameters:
type - the primary type, null is equivalent to MEDIA_TYPE_WILDCARD.
subtype - the subtype, null is equivalent to MEDIA_TYPE_WILDCARD.
parameters - a map of media type parameters, null is the same as an empty map.

MediaType

public MediaType(java.lang.String type,
                 java.lang.String subtype)
Creates a new instance of MediaType with the supplied type and subtype.

Parameters:
type - the primary type, null is equivalent to MEDIA_TYPE_WILDCARD
subtype - the subtype, null is equivalent to MEDIA_TYPE_WILDCARD

MediaType

public MediaType()
Creates a new instance of MediaType, both type and subtype are wildcards. Consider using the constant WILDCARD_TYPE instead.

Method Detail

valueOf

public static MediaType valueOf(java.lang.String type)
                         throws java.lang.IllegalArgumentException
Creates a new instance of MediaType by parsing the supplied string.

Parameters:
type - the media type string
Returns:
the newly created MediaType
Throws:
IllegalArgumentException - if the supplied string cannot be parsed or is null

getType

public java.lang.String getType()
Getter for primary type.

Returns:
value of primary type.

isWildcardType

public boolean isWildcardType()
Checks if the primary type is a wildcard.

Returns:
true if the primary type is a wildcard

getSubtype

public java.lang.String getSubtype()
Getter for subtype.

Returns:
value of subtype.

isWildcardSubtype

public boolean isWildcardSubtype()
Checks if the subtype is a wildcard

Returns:
true if the subtype is a wildcard

getParameters

public java.util.Map<java.lang.String,java.lang.String> getParameters()
Getter for a read-only parameter map. Keys are case-insensitive.

Returns:
an immutable map of parameters.

isCompatible

public boolean isCompatible(MediaType other)
Check if this media type is compatible with another media type. E.g. image/* is compatible with image/jpeg, image/png, etc. Media type parameters are ignored. The function is commutative.

Parameters:
other - the media type to compare with
Returns:
true if the types are compatible, false otherwise.

equals

public boolean equals(java.lang.Object obj)
Compares obj to this media type to see if they are the same by comparing type, subtype and parameters. Note that the case-sensitivity of parameter values is dependent on the semantics of the parameter name, see HTTP/1.1. This method assumes that values are case-sensitive.

Overrides:
equals in class java.lang.Object
Parameters:
obj - the object to compare to
Returns:
true if the two media types are the same, false otherwise.

hashCode

public int hashCode()
Generate a hashcode from the type, subtype and parameters.

Overrides:
hashCode in class java.lang.Object
Returns:
a hashcode

toString

public java.lang.String toString()
Convert the media type to a string suitable for use as the value of a corresponding HTTP header.

Overrides:
toString in class java.lang.Object
