Constructor Detail

Base64

public Base64()

Instantiate a Base64 object.

Base64

public Base64(java.lang.String content)

Instantiate a Base64 object with encoded content.

Parameters:

content - Encoded content

Base64

public Base64(java.io.InputStream stream)

Instantiate a Base64 object with a content stream. Objects instantiated with this constructor must not attempt to add content to the list returned by the getContent() method.

Parameters:

stream - Input stream

Method Detail

getContent

public java.util.List getContent()

Get content model.

Specified by:

getContent in interface MetsSerializable

Returns:

Null

add

public void add(java.lang.String content)

Add additional Base64-encoded content.

Parameters:

content - Encoded content

decode

public void decode(MetsWriter w)
            throws MetsException

De-serialize this element and its content model as Base64. Reference XML Schema Datatype description for base64Binary. Note that any whitespace characters ('\t','\r','\n',' ') are replaced with a space and subsequently any continuous whitespace characters are collapsed into a single space, per the XML Schema Datatype definition of the base64Binary type.

Parameters:

w - Writer

Throws:

MetsException

encode

public void encode(MetsWriter w)
            throws MetsException

Serialize this element and its content model as Base64.

Parameters:

w - Writer

Throws:

MetsException

reader

public static Base64 reader(MetsReader r)
                     throws MetsException

Instantiate a Base64 object de-serialized from the input stream.

Parameters:

r - Reader

Returns:

Base64 object

Throws:

MetsException - De-serializing exception

read

public void read(MetsReader r)
          throws MetsException

De-serialize this element and its content model.

Specified by:

read in interface MetsSerializable

Parameters:

r - Reader

Throws:

MetsException

write

public void write(MetsWriter w)
           throws MetsException

Serialize this element and its content model. Calls encode().

Specified by:

write in interface MetsSerializable

Parameters:

w - Writer

Throws:

MetsException
