primaryType - primary type

subType - subType

list - ParameterList

ContentType

public ContentType(String s)
            throws ParseException

Parameters:

s - the Content-Type string.

Throws:

ParseException - if the parse fails.

Method Detail

getPrimaryType

public String getPrimaryType()

Return the primary type.

Returns:

the primary type

getSubType

public String getSubType()

Return the subType.

Returns:

the subType

getBaseType

public 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 String getParameter(String name)

Return the specified parameter value. Returns null if this parameter is absent.

Parameters:

name - the parameter name

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(String primaryType)

Set the primary type. Overrides existing primary type.

Parameters:

primaryType - primary type

setSubType

public void setSubType(String subType)

Set the subType. Replaces the existing subType.

Parameters:

subType - the subType

setParameter

public void setParameter(String name,
                         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 String toString()

Retrieve a RFC2045 style string representation of this Content-Type. Returns an empty string if the conversion failed.

Overrides:

toString in class 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:

cType - ContentType to compare this against

Returns:

true if it matches

match

public boolean match(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/*"

Parameters:

s - the content-type string to match

Returns:

true if it matches
