Method Detail

asByteArray

public static byte[] asByteArray(java.io.InputStream in)
                          throws java.lang.IllegalArgumentException

Obtains the contents of the specified stream as a byte array

Parameters:

in -

Returns:

the byte[] for the given InputStream

Throws:

java.lang.IllegalArgumentException - If the stream was not specified

asUTF8String

public static java.lang.String asUTF8String(java.io.InputStream in)

Obtains the contents of the specified stream as a String in UTF-8 charset.

Parameters:

in -

Throws:

java.lang.IllegalArgumentException - If the stream was not specified

copy

public static void copy(java.io.InputStream input,
                        java.io.OutputStream output)
                 throws java.io.IOException

Copies the contents from an InputStream to an OutputStream. It is the responsibility of the caller to close the streams passed in when done, though the OutputStream will be fully flushed.

Parameters:

input -

output -

Throws:

java.io.IOException - If a problem occurred during any I/O operations

copy

public static int copy(java.io.InputStream input,
                       java.io.OutputStream output,
                       int len)
                throws java.io.IOException

Copies the specified number of bytes from an InputStream to an OutputStream. It is the responsibility of the caller to close the streams passed in when done, though the OutputStream will be fully flushed.

Parameters:

input -

output -

len - the number of bytes to copy

Returns:

number of bytes copied

Throws:

java.io.IOException - If a problem occurred during any I/O operations

bufferedWriteWithFlush

public static void bufferedWriteWithFlush(java.io.OutputStream output,
                                          byte[] content)
                                   throws java.io.IOException

Writing the specified contents to the specified OutputStream using an internal buffer. Flushing the stream when completed. Caller is responsible for opening and closing the specified stream.

Parameters:

output - The OutputStream

content - The content to write to the specified stream

Throws:

java.io.IOException - If a problem occured during any I/O operations

copyWithClose

public static void copyWithClose(java.io.InputStream input,
                                 java.io.OutputStream output)
                          throws java.io.IOException

Copies the contents from an InputStream to an OutputStream and closes both streams.

Parameters:

input -

output -

Throws:

java.io.IOException - If a problem occurred during any I/O operations during the copy, but on closing the streams these will be ignored and logged at Level.FINER
