Constructor Detail

ContentType

public ContentType()
No-arg Constructor.

ContentType

public ContentType(java.lang.String primaryType,
                   java.lang.String subType,
                   ParameterList list)
Constructor.
Parameters:
primaryType - primary type
subType - subType
list - ParameterList

ContentType

public ContentType(java.lang.String s)
            throws ParseException
Constructor that takes a Content-Type string. The String is parsed into its constituents: primaryType, subType and parameters. A ParseException is thrown if the parse fails.
Parameters:
s - the Content-Type string.
Throws:
ParseException - if the parse fails.
Method Detail

getPrimaryType

public java.lang.String getPrimaryType()
Return the primary type.
Returns:
the primary type

getSubType

public java.lang.String getSubType()
Return the subType.
Returns:
the subType

getBaseType

public java.lang.String getBaseType()
Return the MIME type string, without the parameters. The returned value is basically the concatenation of the primaryType, the '/' character and the secondaryType.
Returns:
the type

getParameter

public java.lang.String getParameter(java.lang.String name)
Return the specified parameter value. Returns null if this parameter is absent.
Returns:
parameter value

getParameterList

public ParameterList getParameterList()
Return a ParameterList object that holds all the available parameters. Returns null if no parameters are available.
Returns:
ParameterList

setPrimaryType

public void setPrimaryType(java.lang.String primaryType)
Set the primary type. Overrides existing primary type.
Parameters:
primaryType - primary type

setSubType

public void setSubType(java.lang.String subType)
Set the subType. Overrides existing subType
Parameters:
type - subType

setParameter

public void setParameter(java.lang.String name,
                         java.lang.String value)
Set the specified parameter. If this parameter already exists, it is replaced by this new value.
Parameters:
name - parameter name
value - parameter value

setParameterList

public void setParameterList(ParameterList list)
Set a new ParameterList.
Parameters:
list - ParameterList

toString

public java.lang.String toString()
Retrieve a RFC2045 style string representation of this Content-Type. Returns null if the conversion failed.
Overrides:
toString in class java.lang.Object
Returns:
RFC2045 style string

match

public boolean match(ContentType cType)
Match with the specified ContentType object. This method compares only the primaryType and subType . The parameters of both operands are ignored.

For example, this method will return true when comparing the ContentTypes for "text/plain" and "text/plain; charset=foobar". If the subType of either operand is the special character '*', then the subtype is ignored during the match. For example, this method will return true when comparing the ContentTypes for "text/plain" and "text/*"

Parameters:
ContentType - to compare this against

match

public boolean match(java.lang.String s)
Match with the specified content-type string. This method compares only the primaryType and subType . The parameters of both operands are ignored.

For example, this method will return true when comparing the ContentType for "text/plain" with "text/plain; charset=foobar". If the subType of either operand is the special character '*', then the subtype is ignored during the match. For example, this method will return true when comparing the ContentType for "text/plain" with "text/*"
