Constructor Detail

AttributeSet

public AttributeSet()

Create an empty attribute set

Method Detail

setName

public void setName(StructuredQName attributeSetName)

Set the name of the attribute-set

Parameters:

attributeSetName - the name of the attribute-set

setUseAttributeSets

public void setUseAttributeSets(AttributeSet[] useAttributeSets)

Set the attribute sets used by this attribute set

Parameters:

useAttributeSets - the set of attribute sets used by this attribute set

setStackFrameMap

public void setStackFrameMap(SlotManager stackFrameMap)

Set the stack frame map which allocates slots to variables declared in this attribute set

Overrides:

setStackFrameMap in class Procedure

Parameters:

stackFrameMap - the stack frame map

getFocusDependencies

public int getFocusDependencies()

Determine whether the attribute set has any dependencies on the focus

Returns:

the dependencies

expand

public void expand(XPathContext context)
            throws XPathException

Evaluate an attribute set

Parameters:

context - the dynamic context

Throws:

XPathException - if any failure occurs

getConstructType

public int getConstructType()

Get the type of construct. This will either be the fingerprint of a standard XSLT instruction name (values in StandardNames: all less than 1024) or it will be a constant in class Location.

Returns:

an integer identifying the kind of construct

getObjectName

public StructuredQName getObjectName()

Get a name identifying the object of the expression, for example a function name, template name, variable name, key name, element name, etc. This is used only where the name is known statically.

Returns:

the QName of the object declared or manipulated by this instruction or expression

expand

public static void expand(AttributeSet[] asets,
                          XPathContext context)
                   throws XPathException

Expand (evaluate) an array of attribute sets

Parameters:

asets - the attribute sets to be evaluated

context - the run-time context to use

Throws:

XPathException - if evaluation of any attribute-set fails with a dynamic error
