Method Detail

available

public int available()

Returns the number of bytes that can be read without blocking. Since there is no blocking possible here, we simply try to return the number of bytes available at all. In case the length of the stream is indefinite, we return the highest number that can be represented in an integer. If the length if finite, this length is returned, clipped by the maximum that can be represented.
