public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

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.

Specified by:

incrementResourceUsers in class ASInputStream

decrementResourceUsers

public void decrementResourceUsers()

Description copied from class: ASInputStream

Method decrements number of resource users.

Specified by:
