public Template()

Method Detail

init

public void init(int templateFingerprint,
                 int precedence,
                 int minImportPrecedence)

setBody

public void setBody(Expression body)

Overrides:

setBody in class Procedure

getFingerprint

public int getFingerprint()

Get the namepool fingerprint of the name of the template (if it is named)

Returns:

the fingerprint of the template name, or -1 if unnamed

getPrecedence

public int getPrecedence()

getMinImportPrecedence

public int getMinImportPrecedence()

setHasRequiredParams

public void setHasRequiredParams(boolean has)

hasRequiredParams

public boolean hasRequiredParams()

apply

public void apply(XPathContext context,
                  Rule rule)
           throws XPathException

Process the template, without returning any tail calls

Parameters:

context - The dynamic context, giving access to the current node,

rule -

Throws:

XPathException

applyLeavingTail

public TailCall applyLeavingTail(XPathContext context,
                                 Rule rule)
                          throws XPathException

Process this template, with the possibility of returning a tail call package if the template contains any tail calls that are to be performed by the caller.

Throws:

XPathException

expand

public TailCall expand(XPathContext context)
                throws XPathException

Expand the template. Called when the template is invoked using xsl:call-template. Invoking a template by this method does not change the current template.

Throws:

XPathException

getInstructionInfo

public InstructionInfo getInstructionInfo()

Get the InstructionInfo details about the construct. This information isn't used for tracing, but it is available when inspecting the context stack.

Specified by:

getInstructionInfo in interface InstructionInfoProvider

hasBadParentPointer

public boolean hasBadParentPointer()

Diagnostic method

Returns:

true if the template contains an expression with a bad parent pointer
