Parameters:
type - the MimeType object to compare with
Returns:
true if they match

match

public boolean match(String rawdata)
              throws MimeTypeParseException

Determine if the primary and sub type of this object is the same as the content type described in rawdata.

Parameters:
rawdata - the MIME type string to compare with
Returns:

Throws:
MimeTypeParseException

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

The object implements the writeExternal method to save its contents by calling the methods of DataOutput for its primitive values or calling the writeObject method of ObjectOutput for objects, strings and arrays.

Specified by:
writeExternal in interface Externalizable
Parameters:
out - the ObjectOutput object to write to
Throws:
IOException - Includes any I/O exceptions that may occur

readExternal

public void readExternal(ObjectInput in)
                  throws IOException,
                         ClassNotFoundException

The object implements the readExternal method to restore its contents by calling the methods of DataInput for primitive types and readObject for objects, strings and arrays. The readExternal method must read the values in the same sequence and with the same types as were written by writeExternal.

Specified by:
