java.lang.Objectjava.io.InputStream
com.ibm.as400.access.PrintObjectInputStream
The PrintObjectInputStream class is used to read data out of a system spooled file or AFP resource such as an overlay or page segment.
An instance of this class can be created either by using the getInputStream method from the AFPResource class or by using the getInputStream method from the SpooledFile class.
Method Summary | |
---|---|
int |
available()
Returns the number of bytes that can be read without blocking. |
void |
close()
Closes the input stream. |
void |
mark(int readLimit)
Marks the current position in the input stream. |
boolean |
markSupported()
Returns a boolean indicating whether this stream type supports mark/reset. |
int |
read()
Reads the next byte of data from this input stream. |
int |
read(byte[] data)
Reads up to data.length bytes of data from this input stream into data. |
int |
read(byte[] data,
int dataOffset,
int length)
Reads up to length bytes of data from this input stream into data, starting at the array offset dataOffset. |
void |
reset()
Repositions the stream to the last marked position. |
long |
skip(long bytesToSkip)
Skips over the next bytesToSkip bytes in the stream. |
