public class PlatformDependency
extends InstallNode
This is a sample of a product dependency that depends on the runtime platform of the wizard.

PlatformDependency is a generic InstallNode that you can insert into a product tree to affect what is visible below it. Calling upon the refresh() method with a target of "nodeIsActive" will make the dependency enforce its rules by checking its dependency, and turning on or off its children.

Variable Index

o invert
A flag indicating this dependency should be inverted (equivelent to the boolean operation 'not') Deprecated.
o platform
The platform this dependency is configured with.

Constructor Index

o PlatformDependency()
Constructs a new PlatformDependency with no configured platforms.
o PlatformDependency(Platform, boolean)
Constructs a new platform dependency with required information, including inversion.

Method Index

o addRuntimeResources(Vector)
Add the required resources when this object is used in the Product Tree.
o getInvert()
Gets the invert state of this InstallComponent
o initialize(WizardState)
Initialize this object.
o refresh(Vector, String)
Update this dependency.
o setInvert(boolean)
Sets the invert state of this InstallComponent

Variables

o invert 
 protected boolean invert
Note: invert is deprecated. use set/getInvert()

A flag indicating this dependency should be inverted (equivelent to the boolean operation 'not')

o platform 
 protected Platform platform
The platform this dependency is configured with. This determines whether the children of this dependency participate in tree operations or not.

Constructors

o PlatformDependency 
 public PlatformDependency()
Constructs a new PlatformDependency with no configured platforms.

o PlatformDependency 
 public PlatformDependency(Platform platform,
                           boolean inverted)
Constructs a new platform dependency with required information, including inversion.

Parameters:
platform - The platform this dependency depends on. Children of this node will not be allowed to participate in installs if this platform is not the runtime platform, unless inverted is true.
inverted - A flag indicating this dependency should invert its results. If this is false, the dependency does not allow participation of its children if the runtime platform does not match the supplied platform

Methods

o getInvert 
 public boolean getInvert()
Gets the invert state of this InstallComponent

Returns:
The invert state of this component
o setInvert 
 public void setInvert(boolean invert)
Sets the invert state of this InstallComponent

Parameters:
invert - The new invert state
o refresh 
 public boolean refresh(Vector targets,
                        String sharedPoolKey)
Update this dependency. For example, if we are on a Windows-based platform and this InstallComponent has some children that should only be installed on SPARC-based platforms, this would omit the inactive InstallComponent's information (Destination table, whether it will install or not). In effect, it halts any data-gathering operation that might otherwise be passed down to its children. For a SoftwareComponent, this method searches for it being "selected" by the user, and turns itself "off" if it is not selected.

Parameters:
targets - The target properties (set via setProperty()) to update.
sharedPoolKey - the key used to access the list of already-visited shared components.
Returns:
true if the refresh was sucessful, falseotherwise.
Overrides:
refresh in class InstallNode
o addRuntimeResources 
 public void addRuntimeResources(Vector resourceVector)
Add the required resources when this object is used in the Product Tree.

Parameters:
resourceVector - The vector containing all of the required resources for this class
Overrides:
addRuntimeResources in class InstallNode
o initialize 
 public boolean initialize(WizardState state)
Initialize this object. For Platform Dependencies, all we have to do is check the dependency in order to initialize.

Parameters:
state - The WizardState this object belongs to.
Returns:
Whether the initialization was successful or not.
Overrides:
initialize in class InstallNode
