Constructor Detail

RuleManager

public RuleManager(NamePool pool)

create a RuleManager and initialise variables

Method Detail

setStandaloneContext

public void setStandaloneContext(StandaloneContext context)

Set the standalone context for XPath expressions and patterns. This is used only for expressions and patterns occurring outside the context of a stylesheet.

getStandaloneContext

public StandaloneContext getStandaloneContext()

Get the standalone context for XPath expressions and patterns. This is used only for expressions and patterns occurring outside the context of a stylesheet.

Returns:

the StandaloneContext associated with this RuleManager. Creates a new one if none has been set explicitly.

resetHandlers

public void resetHandlers()

Set up a new table of handlers.

getMode

public Mode getMode(int modeNameCode)

Get the Mode object for a named mode. If there is not one already registered. a new Mode is created.

Parameters:

modeNameCode - The name code of the mode. Supply -1 to get the default mode.

setHandler

public void setHandler(java.lang.String pattern,
                       NodeHandler eh)
                throws XPathException

Register a handler for a particular pattern. This is a convenience interface that calls setHandler(pattern, eh, mode, precedence) with default mode and precedence.

Parameters:

pattern - A match pattern

eh - The NodeHandler to be used

Throws:

XPathException

NodeHandler, Pattern

setHandler

public void setHandler(Pattern pattern,
                       NodeHandler eh,
                       Mode mode,
                       int precedence)

Register a handler for a particular pattern. The priority of the rule is the default priority for the pattern, which depends on the syntax of the pattern suppllied.

Parameters:

pattern - A match pattern

eh - The ElementHandler to be used

mode - The processing mode

precedence - The import precedence (use 0 by default)

setHandler

public void setHandler(Pattern pattern,
                       NodeHandler eh,
                       Mode mode,
                       int precedence,
                       double priority)

Register a handler for a particular pattern.

Parameters:

pattern - Must be a valid Pattern.

eh - The ElementHandler to be used

mode - The processing mode to which this element handler applies

precedence - The import precedence of this rule

priority - The priority of the rule: if an element matches several patterns, the one with highest priority is used

getHandler

public NodeHandler getHandler(NodeInfo node,
                              Context c)
                       throws TransformerException

Find the handler registered for a particular node in default mode.

Parameters:

node - The NodeInfo for the relevant node

Returns:

The handler that will process this node. Returns the default handler for the type of node if there is no specific one registered.

Throws:

TransformerException

getHandler

public NodeHandler getHandler(NodeInfo node,
                              Mode mode,
                              Context c)
                       throws TransformerException

Find the handler registered for a particular node in a specific mode.

Parameters:

node - The NodeInfo for the relevant node

mode - The processing mode

Returns:

The handler that will process this node Returns null if there is no specific handler registered.

Throws:

TransformerException

getHandler

public NodeHandler getHandler(NodeInfo node,
                              Mode mode,
                              int min,
                              int max,
                              Context c)
                       throws XPathException

Get a handler whose import precedence is in a particular range. This is used to support the xsl:apply-imports function

Throws:

XPathException

getAllModes

public java.util.Enumeration getAllModes()

Get a list of all registered modes

Returns:

an Enumeration of all modes in use, excluding the default (unnamed) mode
