Constructor Detail

HotDeploymentStrategy

public HotDeploymentStrategy(ClassLoader classLoader,
                             File hotDeployDirectory,
                             boolean enabled)

Parameters:

classLoader - The parent classloader of the hot deployment classloader

hotDeployDirectory - The directory in which hot deployable Seam components are placed

Method Detail

available

public boolean available()

It is both enabled and the classpath was detected. Admittedly, this seems like a redundant confirmation.

isEnabled

public boolean isEnabled()

isHotDeployClassLoaderEnabled

public boolean isHotDeployClassLoaderEnabled()

getDeploymentHandlersKey

protected String getDeploymentHandlersKey()

Specified by:

getDeploymentHandlersKey in class DeploymentStrategy

getHotDeploymentPaths

public File[] getHotDeploymentPaths()

Get all hot deployable paths

isFromHotDeployClassLoader

public boolean isFromHotDeployClassLoader(Class componentClass)

Return true if the component is from a hot deployment classloader

createInstance

public static HotDeploymentStrategy createInstance(String className,
                                                   ClassLoader classLoader,
                                                   File hotDeployDirectory,
                                                   boolean enabled)

Dynamically instantiate a HotDeploymentStrategy Needed to prevent dependency on optional librarires

Parameters:

className - The strategy to use

classLoader - The classloader to use with this strategy

hotDeployDirectory - The directory which contains hot deployable Seam components
