org.apache.axiom.attachments.BoundaryPushbackInputStream
- All Implemented Interfaces:
- java.io.Closeable
public class BoundaryPushbackInputStream
- extends java.io.InputStream
An InputStream that reads bytes up to a boundary.
The boundary is not logically part of the bytes to read.
The wrapped PushbackInputStream is set to to the byte after
the boundary once the bytes are read.
The boundary is not logically returned.
There are two forms that are supported, where . is a byte
.......................boundary
and
..................../r/nboundary
In both cases, only the bytes (.) are returned.

public int read(byte[] b,
int off,
int len)
throws java.io.IOException

- Overrides:
read
in class java.io.InputStream
