Method Detail

copy

public void copy(java.io.InputStream from,
                 java.io.OutputStream to)
          throws java.io.IOException

Reads the data from the Input stream and writes to the output stream Buffers each stream. Terminates when a read from the Input stream results in EOF

Throws:

java.io.IOException

readString

public java.lang.String readString(java.io.InputStream from)
                            throws java.io.IOException

reads the entire contents of stream into a String

Throws:

java.io.IOException

getResourceAsStream

public java.io.InputStream getResourceAsStream(java.lang.String name)

Uses ClassLoader which loaded Streams.class to obtain resource

Returns:

an InputStream

Throws:

java.util.MissingResourceException

getResourceAsStream

public java.io.InputStream getResourceAsStream(java.lang.Class aClass,
                                               java.lang.String name)

Convenience method to check for MissingResource (null stream)

Returns:

an InputStream

Throws:

java.util.MissingResourceException

createFileFromResource

public void createFileFromResource(java.lang.String resourceName,
                                   java.io.File file)

Copies a resource to the location specified by the File parameter.

expandResourceJar

public void expandResourceJar(java.io.File outputDir,
                              java.lang.String jarResourceName)

If the jar exists as a resource, the contents of the jar will be expanded on the file system in the location specified by the File parameter. If any files already exist, they will not be over-written.

loadProperties

public java.util.Properties loadProperties(java.lang.String resourceName,
                                           java.io.PrintStream err)
