Field Detail

data

protected DataSource data

The signature data.

mimeType

protected String mimeType

characterEncoding

protected String characterEncoding

The character encoding of the data if appropriate, or null if not.

Constructor Detail

SignatureDataImpl

public SignatureDataImpl(DataSource data,
                         String mime_type)

Constructor that fills the SignatureData.

The charactor encoding is set to null, so this constructor is primarily for signature data that has no character encoding (e.g. binary data).

Parameters:

data - The signature data.

mime_type - The mime type of the data.

SignatureDataImpl

public SignatureDataImpl(DataSource data,
                         String mime_type,
                         String character_encoding)

Method Detail

getDataSource

public DataSource getDataSource()

Description copied from interface: SignatureData

Returns the DataSource that provides the data for this SignatureData.

Specified by:

getDataSource in interface SignatureData

Returns:

Returns the DataSource.

See Also:

SignatureData.getDataSource()

getMimeType

public String getMimeType()

Description copied from interface: SignatureData

Returns the mime type of the data.

E.g. "text/plain" for text data or "application/pdf" for a PDF.

Specified by:

getMimeType in interface SignatureData

Returns:

Returns the mime type of the data.

SignatureData.getMimeType()

getCharacterEncoding

public String getCharacterEncoding()

Description copied from interface: SignatureData

Returns the character encoding (charset) of the data if appropriate.

This is only appropriate if the mime type suggests that the data contained in here is textually encoded. Usually text/plain or similar data types will have a character encoding present.

If no character encoding is present, null is returned here.

E.g. "UTF-8" is the most common encoding for textual data.

Specified by:

getCharacterEncoding in interface SignatureData

Returns:

Returns the character encoding (charset) of the data if appropriate.
