Constructor Detail

Base64FilterInputStream

public Base64FilterInputStream(java.io.InputStream in)

Given some InputStream, create an InputStream that Base64 encodes the input stream. No line breaks are included in the output.

Parameters:

in - an InputStream providing source data for encoding

Base64FilterInputStream

public Base64FilterInputStream(java.io.InputStream in,
                               boolean breakLines)

Given some InputStream, create an InputStream that Base64 encodes the input stream.

Parameters:

in - an InputStream providing source data for encoding

breakLines - if true, add line breaks in the output

Method Detail

read

public int read()
         throws java.io.IOException

Reads the next byte of data from the input stream and returns it. Returns (int) -1 if at EOF.

Overrides:

read in class java.io.FilterInputStream

Throws:

java.io.IOException

read

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

Reads up to len bytes of data from the input stream into an array of bytes. Returns the actual number of bytes written to the array.

Overrides:

read in class java.io.FilterInputStream

Throws:

java.io.IOException

markSupported

public boolean markSupported()

This implementation does not support mark() or reset().

Overrides:

markSupported in class java.io.FilterInputStream

Returns:

false

available

public int available()
              throws java.io.IOException

Return the number of bytes available to read.

Overrides:

available in class java.io.FilterInputStream

Throws:

java.io.IOException

skip

public long skip(long n)
          throws java.io.IOException

Skip over bytes in the input stream.

Overrides:

skip in class java.io.FilterInputStream

Parameters:

n - number of bytes to skip

Returns:

number of bytes skipped

Throws:

java.io.IOException
