java.lang.ClassLoader

com.rational.test.ft.RationalFtClassLoader

public class RationalFtClassLoader
extends java.lang.ClassLoader

This class loader is given a path when constructed, and it knows to load classes on that path. We'll use it to load our classes when we infest the SUT, giving it the path to where Functional Tester jar is installed. This will allow us to load our classes into the SUT without being on the CLASSPATH.

Constructor Detail

RationalFtClassLoader

public RationalFtClassLoader(java.lang.String[] path)

Construct an FtClassLoader, and give it the path it should use for loading our classes.

Parameters:

path - The directories and jars (separated by the path.separator

See Also:

File.pathSeparator

RationalFtClassLoader

public RationalFtClassLoader(java.lang.String[] path,
                     java.lang.ClassLoader parentClassLoader)

Construct an FtClassLoader, and give it the path it should use for loading our classes.

Parameters:

path - The directories and jars (separated by the path.separator

See Also:

File.pathSeparator

Method Detail

loadClass

protected java.lang.Class loadClass(java.lang.String name,
                        boolean resolve)
                             throws java.lang.ClassNotFoundException

This overrides ClassLoader.loadClass(). The loadClass method loads a single class on our path.

Overrides:

loadClass in class java.lang.ClassLoader

Throws:

java.lang.ClassNotFoundException

readFile

public byte[] readFile(java.lang.String fileName)

This is our readFile(), overriding the one in ClassLoader. Return the byte contents of the given file, looking on our classpath.

Parameters:

fileName - The file name

Returns:

!null - the bytes

null - not found.

getResourceAsStream

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

Overrides the same-named method in ClassLoader.

Returns an input stream for reading the specified resource.

Overrides:

getResourceAsStream in class java.lang.ClassLoader

Parameters:

name - the resource name

Returns:

an input stream for reading the resource, or null if the resource could not be found

Since:

JDK1.1

getResource

public java.net.URL getResource(java.lang.String name)

Overrides the same-named method in ClassLoader. Finds the resource with the given name. A resource is some data (images, audio, text, etc) that can be accessed by class code in a way that is independent of the location of the code.

The name of a resource is a "/"-separated path name that identifies the resource.

Overrides:

getResource in class java.lang.ClassLoader

Parameters:

name - resource name

Returns:

a URL for reading the resource, or null if the resource could not be found or the caller doesn't have adequate privileges to get the resource.

Since:

JDK1.1

See Also:

findResource(String)

findResource

protected java.net.URL findResource(java.lang.String name)

Overrides the same-named method in ClassLoader. Finds the resource with the given name.

Overrides:

findResource in class java.lang.ClassLoader

Parameters:

name - the resource name

Returns:

a URL for reading the resource, or null if the resource could not be found

Since:

JDK1.2

append

public void append(java.lang.String[] path)

Append the specified directories and jars to the existing path

Parameters:

path - The directories and jars (separated by the path.separator

See Also:

File.pathSeparator

prepend

public void prepend(java.lang.String[] path)

Prepend the specified directories and jars to the existing path

Parameters:

path - The directories and jars (separated by the path.separator
