Method Details
-
reset
public void reset()Description copied from interface:ContentInputBuffer
Resets the buffer by clearing its state and stored content.- Specified by:
reset
in interfaceContentInputBuffer
-
consumeContent
Description copied from interface:ContentInputBuffer
Reads content from the givenContentDecoder
and stores it in this buffer.- Specified by:
consumeContent
in interfaceContentInputBuffer
- Parameters:
decoder
- the content decoder.- Returns:
- number of bytes read.
- Throws:
IOException
- in case of an I/O error.
-
isEndOfStream
public boolean isEndOfStream() -
read
Description copied from interface:ContentInputBuffer
Reads one byte from this buffer. If the buffer is empty this method can throw a runtime exception. The exact type of runtime exception thrown by this method depends on implementation. This method returns-1
if the end of content stream has been reached.- Specified by:
read
in interfaceContentInputBuffer
- Returns:
- one byte
- Throws:
IOException
-
read
Description copied from interface:ContentInputBuffer
Reads up tolen
bytes of data from this buffer into an array of bytes. The exact number of bytes read depends how many bytes are stored in the buffer.If
off
is negative, orlen
is negative, oroff+len
is greater than the length of the arrayb
, this method can throw a runtime exception. The exact type of runtime exception thrown by this method depends on implementation. This method returns-1
if the end of content stream has been reached.- Specified by:
read
in interfaceContentInputBuffer
- Parameters:
b
- the buffer into which the data is read.off
- the start offset in arrayb
at which the data is written.len
- the maximum number of bytes to read.- Returns:
- the total number of bytes read into the buffer, or
-1
if there is no more data because the end of the stream has been reached. - Throws:
IOException
- if an I/O error occurs.
