int |
consumeContent(ContentDecoder decoder)
Reads content from the given
ContentDecoder and stores it in
this buffer. |
boolean |
isEndOfStream() |
int |
read()
Reads one byte from this buffer.
|
int |
read(byte[] b) |
int |
read(byte[] b,
int off,
int len)
Reads up to
len bytes of data from this buffer into
an array of bytes. |
void |
reset()
Resets the buffer by clearing its state and stored content.
|

ContentInputBuffer
len
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, or len
is negative, or
off+len
is greater than the length of the array
b
, 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.
