Method Detail

getInputStream

public InputStream getInputStream()

Description copied from interface: Document

An input stream on the byte[] stored in the IContentRepository.

Specified by:

getInputStream in interface Document

getReader

public Reader getReader()
                 throws UnsupportedEncodingException

Description copied from interface: Document

A reader on the byte[] stored in the IContentRepository where bytes are decoded to characters using the encoding identified by DocumentHeader.getContentEncoding().

Specified by:

getReader in interface Document

Throws:

UnsupportedEncodingException

copyStream

public void copyStream(byte[] b,
              int off,
              int len)

Set the content by copying the byte[].

Note: Do NOT use this when the content is character data since the encoding attribute will NOT be set.

Parameters:

b - The content.

off - The offset of the 1st byte to be copied.

len - The #of bytes to be copied.

copyStream

public void copyStream(byte[] b)

Set the content by copying the byte[].

Note: Do NOT use this when the content is character data since the encoding attribute will NOT be set.

Parameters:

b - The content.

copyStream

public void copyStream(InputStream is)
                throws IOException

Set the content by copying the given stream.

Note: Do NOT use this when the content is character data since the encoding attribute will NOT be set.

Parameters:

is -

Throws:

IOException

copyString

public void copyString(String encoding,
              String s)
                throws UnsupportedEncodingException

Set the content by converting characters to into bytes using the specified encoding.

Parameters:

encoding - The encoding that will be used to convert characters to bytes.

s - The string.

Throws:

UnsupportedEncodingException

copyReader

public void copyReader(String encoding,
              Reader r)
                throws IOException
