Constructor Detail

CxVarInstance

public CxVarInstance()

Default contstuctor

CxVarInstance

public CxVarInstance(java.lang.String name)

Constructor

Parameters:

name - the name of the var instance

Method Detail

isVarInstance

public boolean isVarInstance()

Determines if the component is a var instance

Overrides:

isVarInstance in class CxComponent

Returns:

true if the component is a var instance, otherwise false

getEditFrame

public com.dat.cx.studio.CxInternalFrame getEditFrame(com.dat.cx.studio.CxStudio studio)

Get at edit frame for editing this component.

Overrides:

getEditFrame in class CxComponent

Returns:

the edit frame

getDisplay

public com.dat.cx.studio.CxCompDisplay getDisplay()

Get the display peer for this var instance. The display peer handles the rendering of the var instance within the studio.

Overrides:

getDisplay in class CxComponent

Returns:

the display peer

importTemplate

public void importTemplate(CxComponent from,
                           boolean copy,
                           boolean inherit,
                           boolean inverse)

Import the definition of a component from another component. For composite components this will result in instantiating new child components for each of the children of the from component and importing their definition recursively. Note: special handing is provided by each subclass, CxPort, CxInterface, CxProperty, CxLibraryComponent, etc.

Overrides:

importTemplate in class CxComponent

Parameters:

from - the component from which to import a definition

copy - indicate that this is a copy 'vs' extends

inherit - indicate that the definition is inherited as part of an extends

inverse - indicate that polarity is to be inversed (see CxPort and CxInterface)

importSpec

public java.util.Vector importSpec(XSet spec)

Import specification from an XML element

Overrides:

importSpec in class CxComponent

Parameters:

spec - the xml element containing the specification

export

public XSet export(XSet doc,
                   CxProject project)

Export the definition of this var instance.

Overrides:

export in class CxComponent

Parameters:

doc - the XSet docuement being constructed. The definition is added to this document.

Returns:

the XSet document relative to the new definition

getIcon

public java.lang.String getIcon()

Get the icon file name for this component

Overrides:

getIcon in class CxComponent

Returns:

the file name for the icon
