public void addDecimalFormatting(QName name,
                                 DecimalFormatting symbols)

getKey

public Key getKey(QName name)

addKey

public void addKey(QName name,
                   Key key)

addStylesheet

public Stylesheet addStylesheet(QName name,
                                Stylesheet node)

lookupStylesheet

public Stylesheet lookupStylesheet(QName name)

addTemplate

public Template addTemplate(Template template)

lookupTemplate

public Template lookupTemplate(QName name)

addVariable

public Variable addVariable(Variable variable)

addParam

public Param addParam(Param parameter)

lookupVariable

public Variable lookupVariable(QName qname)

lookupParam

public Param lookupParam(QName qname)

lookupName

public SyntaxTreeNode lookupName(QName qname)

addAttributeSet

public AttributeSet addAttributeSet(AttributeSet atts)

lookupAttributeSet

public AttributeSet lookupAttributeSet(QName name)

addPrimop

public void addPrimop(java.lang.String name,
                      MethodType mtype)

Add a primitive operator or function to the symbol table. To avoid name clashes with user-defined names, the prefix PrimopPrefix is prepended.

lookupPrimop

public java.util.Vector lookupPrimop(java.lang.String name)

Lookup a primitive operator or function in the symbol table by prepending the prefix PrimopPrefix.

generateNamespacePrefix

public java.lang.String generateNamespacePrefix()

setCurrentNode

public void setCurrentNode(SyntaxTreeNode node)

lookupNamespace

public java.lang.String lookupNamespace(java.lang.String prefix)

addPrefixAlias

public void addPrefixAlias(java.lang.String prefix,
                           java.lang.String alias)

Adds an alias for a namespace prefix

lookupPrefixAlias

public java.lang.String lookupPrefixAlias(java.lang.String prefix)

Retrieves any alias for a given namespace prefix

excludeURI

public void excludeURI(java.lang.String uri)

Register a namespace URI so that it will not be declared in the output unless it is actually referenced in the output.

excludeNamespaces

public void excludeNamespaces(java.lang.String prefixes)

Exclude a series of namespaces given by a list of whitespace separated namespace prefixes.

isExcludedNamespace

public boolean isExcludedNamespace(java.lang.String uri)

Check if a namespace should not be declared in the output (unless used)

unExcludeNamespaces

public void unExcludeNamespaces(java.lang.String prefixes)

Turn of namespace declaration exclusion

pushExcludedNamespacesContext

public void pushExcludedNamespacesContext()

Exclusion of namespaces by a stylesheet does not extend to any stylesheet imported or included by the stylesheet. Upon entering the context of a new stylesheet, a call to this method is needed to clear the current set of excluded namespaces temporarily. Every call to this method requires a corresponding call to popExcludedNamespacesContext().

popExcludedNamespacesContext

public void popExcludedNamespacesContext()

Exclusion of namespaces by a stylesheet does not extend to any stylesheet imported or included by the stylesheet. Upon exiting the context of a stylesheet, a call to this method is needed to restore the set of excluded namespaces that was in effect prior to entering the context of the current stylesheet.
