PushBackInputStream(java.io.InputStream input,
int size)
Constructor.
|
Modifier and Type | Method and Description |
---|---|
void |
fillBuffer()
This is a method used to fix PDFBox issue 974661, the PDF parsing code needs
to know if there is at least x amount of data left in the stream, but the available()
method returns how much data will be available without blocking.
|
int |
getOffset()
Returns the current byte offset in the file.
|
boolean |
isEOF()
A simple test to see if we are at the end of the stream.
|
int |
peek()
This will peek at the next byte.
|
int |
read() |
int |
read(byte[] b) |
int |
read(byte[] b,
int off,
int len) |
byte[] |
readFully(int length)
Reads a given number of bytes from the underlying stream.
|
void |
unread(byte[] b) |
void |
unread(byte[] b,
int off,
int len) |
void |
unread(int b) |
