Constructor Detail

EboStreamHelper

public EboStreamHelper()

Method Detail

readFully

public static byte[] readFully(File f)
                        throws IOException

Returns the contents of the file as a byte array

readFully

public static byte[] readFully(InputStream in)
                        throws Exception

Returns the contents of the InputStream as a byte array. Does not close the InputStream.

getInputStream

public static InputStream getInputStream(String s)

Create an InputStream for the given String.

Parameters:

s - The string used as input to a stream.

Returns:

An InputStream object

copyOut

public static void copyOut(InputStream in,
                           OutputStream out)
                    throws IOException

Copy the contents of the InputStream to the OutputStream

Parameters:

in - source InputStream of copy request

out - destination OutputStream of copy request

Throws:

com.sssw.fw.util.IOException -

copyOut

public static void copyOut(Reader in,
                           Writer out)
                    throws IOException

Copy the contents of the Reader to the Writer

Parameters:

in - source Reader of copy request

out - destination Writer of copy request

Throws:

com.sssw.fw.util.IOException -

getString

public static String getString(InputStream in)
                        throws IOException

Read the contents of the InputStream and return it as a String

Parameters:

in - source InputStream of copy request

Returns:

String value of input content, or null if empty input stream

Throws:

com.sssw.fw.util.IOException -

shouldBuffer

public static boolean shouldBuffer(InputStream is)

Determine whether or not it will help to wrap the specified InputStream in a BufferedInputStream. For the present, we don't buffer streams that are already bufferred, or streams from ByteBuffers, or streams from Strings.

Parameters:

is - Input stream

Returns:

True iff we think it will help performance to add a buffer

shouldBuffer

public static boolean shouldBuffer(OutputStream is)

Determine whether or not it will help to wrap the specified OutputStream in a BufferedOutputStream. For the present, we don't buffer streams that are already bufferred, or streams from EboByteBuffers, or streams from Strings.

Parameters:

is - Output stream

Returns:

True iff we think it will help performance to add a buffer
