Package de.gebit.integrity.runner.providers

Class InMemoryTestResourceProvider

java.lang.Object

de.gebit.integrity.runner.providers.InMemoryTestResourceProvider

All Implemented Interfaces:

TestResourceProvider

public class InMemoryTestResourceProvider
extends Object
implements TestResourceProvider

This test resource provider holds the entire resources in memory and returns them from memory on demand. It is intended to be used to create fully self-sufficient clones of other resource providers (that typically just enumerate resources from external sources and load them on demand) which can then be transferred over the remoting connection to forks.

Constructor Detail

InMemoryTestResourceProvider

public InMemoryTestResourceProvider()

Default constructor for serialization.

InMemoryTestResourceProvider

public InMemoryTestResourceProvider(TestResourceProvider aSourceProvider,
                                    String aNamePrefix)
                             throws IOException

Creates a new instance that acts as an in-memory copy of the given resource provider.

Parameters:

aSourceProvider - the provider that is to be copied

aNamePrefix - a prefix to be added to all resource names on copy (if null, nothing is added)

Throws:

IOException

Method Detail

setClassLoader

public void setClassLoader(ClassLoader aClassLoader)

getClassLoader

public ClassLoader getClassLoader()

Description copied from interface: TestResourceProvider

Returns the classloader to use for all dynamic class resolving needs.

Specified by:

getClassLoader in interface TestResourceProvider

Returns:

the classloader to use

getResourceNames

public TestResource[] getResourceNames()

Description copied from interface: TestResourceProvider

Returns all known resource names.

Specified by:

getResourceNames in interface TestResourceProvider

Returns:

openResource

public InputStream openResource(TestResource aResourceName)
                         throws IOException

Description copied from interface: TestResourceProvider

Opens a specific named resource. This should return an InputStream at the start of the data of the respective resources, and it is only expected to work if the resource is one of those enumerated by a call to TestResourceProvider.getResourceNames().

Specified by:

openResource in interface TestResourceProvider

Parameters:

aResourceName - the resource to be opened

Returns:

an InputStream to read the resource

Throws:

IOException

closeResource

public void closeResource(TestResource aResourceName,
                          InputStream aResourceStream)
                   throws IOException

Description copied from interface: TestResourceProvider

Closes a specified resources' stream (and all the stuff opened for this stream in the background).

Specified by:

closeResource in interface TestResourceProvider

Parameters:

aResourceName - the resource to be closed

aResourceStream - the resource stream to close

Throws:

IOException
