Class AbstractBoot

java.lang.Object
  extended by org.jfree.base.AbstractBoot
All Implemented Interfaces:
org.jfree.base.modules.SubSystem
Direct Known Subclasses:
BaseBoot

public abstract class AbstractBoot
extends java.lang.Object
implements org.jfree.base.modules.SubSystem

The common base for all Boot classes.

This initializes the subsystem and all dependent subsystems. Implementors of this class have to provide a public static getInstance() method which returns a singleton instance of the booter implementation.

Further creation of Boot object should be prevented using protected or private constructors in that class, or proper initialzation cannot be guaranteed.

Constructor Detail

AbstractBoot

protected AbstractBoot()
Default constructor.

Method Detail

getPackageManager

public org.jfree.base.modules.PackageManager getPackageManager()
Returns the packageManager instance of the package manager.

Specified by:
getPackageManager in interface org.jfree.base.modules.SubSystem
Returns:
The package manager.

getGlobalConfig

public Configuration getGlobalConfig()
Returns the global configuration.

Specified by:
getGlobalConfig in interface org.jfree.base.modules.SubSystem
Returns:
The global configuration.

isBootInProgress

public final boolean isBootInProgress()
Checks, whether the booting is in progress.

Returns:
true, if the booting is in progress, false otherwise.

isBootDone

public final boolean isBootDone()
Checks, whether the booting is complete.

Returns:
true, if the booting is complete, false otherwise.

loadConfiguration

protected abstract Configuration loadConfiguration()
Loads the configuration. This will be called exactly once.

Returns:
The configuration.

start

public final void start()
Starts the boot process.


performBoot

protected abstract void performBoot()
Performs the boot.


getProjectInfo

protected abstract BootableProjectInfo getProjectInfo()
Returns the project info.

Returns:
The project info.

loadBooter

protected AbstractBoot loadBooter(java.lang.String classname)
Loads the specified booter implementation.

Parameters:
classname - the class name.
Returns:
The boot class.

createDefaultHierarchicalConfiguration

protected Configuration createDefaultHierarchicalConfiguration(java.lang.String staticConfig,
                                                               java.lang.String userConfig,
                                                               boolean addSysProps)
Creates a default configuration setup, which loads its settings from the static configuration (defaults provided by the developers of the library) and the user configuration (settings provided by the deployer). The deployer's settings override the developer's settings. If the parameter addSysProps is set to true, the system properties will be added as third configuration layer. The system properties configuration allows to override all other settings.

Parameters:
staticConfig - the resource name of the developers configuration
userConfig - the resource name of the deployers configuration
addSysProps - a flag defining whether to include the system properties into the configuration.
Returns:
the configured Configuration instance.

createDefaultHierarchicalConfiguration

protected Configuration createDefaultHierarchicalConfiguration(java.lang.String staticConfig,
                                                               java.lang.String userConfig,
                                                               boolean addSysProps,
                                                               java.lang.Class source)
Creates a default hierarchical configuration.

Parameters:
staticConfig - the static configuration.
userConfig - the user configuration.
addSysProps - additional system properties.
source - the source.
Returns:
The configuration.

getExtendedConfig

public ExtendedConfiguration getExtendedConfig()
Returns the global configuration as extended configuration.

Specified by:
getExtendedConfig in interface org.jfree.base.modules.SubSystem
Returns:
the extended configuration.
