                int size)
         throws IOException

Specified by:

read in class ASInputStream

Throws:

IOException

read

public int read(byte[] buffer)
         throws IOException

Overrides:

read in class InputStream

Throws:

IOException

skip

public int skip(int size)
         throws IOException

skip in class ASInputStream

Throws:

IOException

closeResource

public void closeResource()
                   throws IOException

Description copied from class: ASInputStream

Closes stream resource. There is a difference between closing stream and closing it's resource. Several streams may have the same resource (e. g. the same file stream) and resource should be closed only after all streams using it are closed.

Specified by:

closeResource in class ASInputStream

Throws:

IOException

reset

public void reset()
           throws IOException

Specified by:

reset in class ASInputStream

Throws:

IOException

close

public void close()
           throws IOException

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Overrides:

close in class ASInputStream

Throws:

IOException

getInputStream

protected ASInputStream getInputStream()

setInputStream

protected void setInputStream(ASInputStream inputStream)

incrementResourceUsers

public void incrementResourceUsers()

Method increments number of resource users. closeResource

Specified by:

incrementResourceUsers in class ASInputStream

decrementResourceUsers

public void decrementResourceUsers()

Description copied from class: ASInputStream

Method decrements number of resource users. closeResource

Specified by:

decrementResourceUsers in class ASInputStream
