com.sun.tools.xjc.reader.gbind.Expression

com.sun.tools.xjc.reader.gbind.Element

Direct Known Subclasses:

SinkNode, SourceNode

public abstract class Element
extends Expression

Expression that represents an alphabet of a regular language.

Since this package is about a regular expression over element declarations, this represents an XML element declaration (hence the name.) Element needs to be interned, meaning one Element per one tag name.

Implements ElementSet to represent a self.

Modifier and Type	Method and Description
void	addNext(Element element) For each element in this set, adds an edge to the given element.
void	buildStronglyConnectedComponents(List<ConnectedComponent> ccs) Builds a set of strongly connected components and puts them all into the given set.
boolean	contains(com.sun.tools.xjc.reader.gbind.ElementSet rhs) Doesn't have to be strict (it's OK for this method to return false when it's actually true) since this is used just for optimization.
boolean	hasSelfLoop()
Iterator<Element>	iterator() Deprecated. if you statically call this method, there's something wrong.

Method Detail

addNext

public void addNext(Element element)

For each element in this set, adds an edge to the given element.

contains

public boolean contains(com.sun.tools.xjc.reader.gbind.ElementSet rhs)

Doesn't have to be strict (it's OK for this method to return false when it's actually true) since this is used just for optimization. (Erring on the other side is NG)

iterator

public Iterator<Element> iterator()

Deprecated. if you statically call this method, there's something wrong.

Just to satisfy the ElementSet contract.

buildStronglyConnectedComponents

public void buildStronglyConnectedComponents(List<ConnectedComponent> ccs)

Builds a set of strongly connected components and puts them all into the given set.

hasSelfLoop

public boolean hasSelfLoop()
