java.lang.Object
  
org.eclipse.jdt.launching.AbstractVMInstallType

All Implemented Interfaces:

IExecutableExtension, IVMInstallType

---

public abstract class AbstractVMInstallType
extends 
Object
implements 
IVMInstallType, 
IExecutableExtension

Abstract implementation of a VM install type. Subclasses should implement

• IVMInstall doCreateVMInstall(String id)
• String getName()
• IStatus validateInstallLocation(File installLocation)

Clients implementing VM install types should subclass this class.

Constructor Detail

AbstractVMInstallType

protected AbstractVMInstallType()

Constructs a new VM install type.

Method Detail

getVMInstalls

public 
IVMInstall[] getVMInstalls()

Description copied from interface: IVMInstallType

Returns all VM instances managed by this VM type.

Specified by:

getVMInstalls in interface IVMInstallType

Returns:

the list of VM instances managed by this VM type

---

disposeVMInstall

public void disposeVMInstall(
String id)

Description copied from interface: IVMInstallType

Remove the VM associated with the given id from the set of VMs managed by this VM type. Has no effect if a VM with the given id is not currently managed by this type. A VM install that is disposed may not be used anymore.

Specified by:

disposeVMInstall in interface IVMInstallType

Parameters:

id - the id of the VM to be disposed.

---

findVMInstall

public 
IVMInstall findVMInstall(
String id)

Description copied from interface: IVMInstallType

Finds the VM with the given id.

Specified by:

findVMInstall in interface IVMInstallType

Parameters:

id - the VM id

Returns:

a VM instance, or null if not found

---

createVMInstall

public 
IVMInstall createVMInstall(
String id)
                           throws 
IllegalArgumentException

Description copied from interface: IVMInstallType

Creates a new instance of this VM Install type. The newly created IVMInstall is managed by this IVMInstallType.

Specified by:

createVMInstall in interface IVMInstallType

Parameters:

id - An id String that must be unique within this IVMInstallType.

Returns:

the newly created VM instance

Throws:

IllegalArgumentException - If the id exists already.

---

doCreateVMInstall

protected abstract 
IVMInstall doCreateVMInstall(
String id)

Subclasses should return a new instance of the appropriate IVMInstall subclass from this method.

Parameters:

id - The vm's id. The IVMInstall instance that is created must return id from its getId() method. Must not be null.

Returns:

the newly created IVMInstall instance. Must not return null.

---

setInitializationData

public void setInitializationData(
IConfigurationElement config,
                                  
String propertyName,
                                  
Object data)

Initializes the id parameter from the "id" attribute in the configuration markup. Subclasses should not override this method.

Specified by:

setInitializationData in interface IExecutableExtension

Parameters:

config - the configuration element used to trigger this execution. It can be queried by the executable extension for specific configuration properties

propertyName - the name of an attribute of the configuration element used on the createExecutableExtension(String) call. This argument can be used in the cases where a single configuration element is used to define multiple executable extensions.

data - adapter data in the form of a String, a Hashtable, or null.

See Also:

IExecutableExtension.setInitializationData(org.eclipse.core.runtime.IConfigurationElement, java.lang.String, java.lang.Object)

---

getId

public 
String getId()

Description copied from interface: IVMInstallType

Returns the globally unique id of this VM type. Clients are responsible for providing a unique id.

Specified by:

getId in interface IVMInstallType

Returns:

the id of this IVMInstallType

---

findVMInstallByName

public 
IVMInstall findVMInstallByName(
String name)

Description copied from interface: IVMInstallType

Finds the VM with the given name.

Specified by:

findVMInstallByName in interface IVMInstallType

Parameters:

name - the VM name

Returns:

a VM instance, or null if not found

---

getDefaultJavadocLocation

public 
URL getDefaultJavadocLocation(
File installLocation)

Returns a URL for the default javadoc location of a VM installed at the given home location, or null if none. The default implementation returns null, subclasses must override as appropriate.

Note, this method would ideally be added to IVMInstallType, but it would have been a breaking API change between 2.0 and 2.1. Thus, it has been added to the abstract base class that VM install types should subclass.

Parameters:

installLocation - home location

Returns:

default javadoc location or null

Since:

2.1

---

getDefaultVMArguments

public 
String getDefaultVMArguments(
File installLocation)

Returns a string of default VM arguments for a VM installed at the given home location, or null if none. The default implementation returns null, subclasses must override as appropriate.

Note, this method would ideally be added to IVMInstallType, but it would have been a breaking API change between 2.0 and 3.4. Thus, it has been added to the abstract base class that VM install types should subclass.

Parameters:

installLocation - home location

Returns:

default VM arguments or null if none

Since:

3.4
