Constructor Detail

Component

public Component(T code,
         Visibility visibility,
         StylesheetPackage containingPackage,
         StylesheetPackage declaringPackage)

Create a component

Parameters:

code - the compiled code that implements the component, for example a Template or Function

visibility - the visibility of the component

containingPackage - the package to which this component belongs

declaringPackage - the package in which the original declaration of the component appears

Method Detail

getComponentBindings

public List<ComponentBinding> getComponentBindings()

Get the component's binding vector; that is the list of external references to other components

Returns:

the binding vector, a list of component bindings. These are identified by a binding slot number held with the individual instruction (such as a call-template instruction or a global variable reference) that contains the external component reference.

setComponentBindings

public void setComponentBindings(List<ComponentBinding> bindings)

Set the component's binding vector; that is the list of external references to other components

Parameters:

bindings - the binding vector, a list of component bindings. These are identified by a binding slot number held with the individual instruction (such as a call-template instruction or a global variable reference) that contains the external component reference.

setVisibility

public void setVisibility(Visibility visibility,
                 boolean explicit)

Set the visibility of the component, and say whether it is explicit or defaulted

Parameters:

visibility - the visibility of the component

explicit - set to true if the visibility is an explicit attribute on the component declaration

getVisibility

public Visibility getVisibility()

Get the visibility of the component

Returns:

the component's visibility. In the declaring package this will be the original declared or exposed visibility; in a using package, it will be the visibility of the component within that package.

isVisibilityExplicit

public boolean isVisibilityExplicit()

Ask whether the visibility of the component is due to an explicit visibility attribute on the component declaration

Returns:

true if the visibility was explicitly declared

getCode

public T getCode()

Get the code (for example a compiled template, function, or variable) that is executed when this component is called

Returns:

the code forming the implementation of this component

getDeclaringPackage

public StylesheetPackage getDeclaringPackage()

Get the declaring package of this component

Returns:

the package in which the code of the component was originally declared

getContainingPackage

public StylesheetPackage getContainingPackage()

Get the containing package of this component

Returns:

the package that contains this (version of the) component

getBaseComponent

public Component<? extends T> getBaseComponent()

Get the component from which this one is derived

Returns:

the component from which this one is derived. This is set when the component appears in the package as a result of xsl:use-package; a component C in the used package is modified to create a component D in the using package, and D.getBaseComponent() returns C. The value will be null in the case of a component whose declaring package is the same as its containing package, that is, an "original" component (including an overriding component)

setBaseComponent

public void setBaseComponent(Component<? extends T> original)

Set the component from which this one is derived

Parameters:

original - the component from which this one is derived. This is set when the component appears in the package as a result of xsl:use-package; a component C in the used package is modified to create a component D in the using package, and D.getBaseComponent() returns C. The value will be null in the case of a component whose declaring package is the same as its containing package, that is, an "original" component (including an overriding component)

export

public void export(ExpressionPresenter out,
          Map<Component,Integer> componentIdMap)
            throws XPathException

Throws:

XPathException

listComponentReferences

public String listComponentReferences(Map<Component,Integer> componentIdMap)
