Field Details

validating

public boolean validating

If set to false, Attributes with no explicit value will not be visited. Explicit value means that the attribute has been present when the model has been created (in source text, SAX event, constructor call), or that it has last been set to a non-null value by attribute.setValue().

Default value of this field is true.

nearestElement

protected E extends TypedElement<E,X> nearestElement

Constructor Details

UntypedVisitor

public UntypedVisitor()

Method Details

getNearestElement

@Opt
public E getNearestElement()

The last entered element.

Returns:

(maybe null) the last entered Element.

action

public void action(TypedDocument<E,X> doc)

To be overridden by the user. This default implementation simply calls descend(TypedDocument)

descend

public void descend(TypedDocument<E,X> doc)

Calls action(TypedElement) for the one top-level element.

match

public void match(TypedSubstantial<X> te)

Distinguishes between action(TypedElement) and action(TypedPCData).

action

public void action(TypedPCData p)

Calls only descend(TypedPCData); can be overridden by the user, if required.

descend

public void descend(TypedPCData p)

Calls descend_precedingEthereals(TypedSubstantial) and descend_followingEthereals(TypedSubstantial).

action

public void action(E el)

Calls only descend(TypedElement); can be overridden by the user, if required.

descend

public void descend(E el)

Calls action/match for preceding and leading Ethereals, than attributes, then contents by descend_contents(TypedElement), then trailing and following Ethereals.

descend_contents

public void descend_contents(E ec)

Calls match(TypedSubstantial) for all contents. (This will in turn call action(TypedElement) or action(TypedPCData).)

descend_leadingEthereals

public void descend_leadingEthereals(TypedEtherealContainer ec)

Calls match(TypedEthereal) for all leading ethereals.

descend_trailingEthereals

public void descend_trailingEthereals(TypedEtherealContainer ec)

Calls match(TypedEthereal) for all trailing ethereals.

descend_precedingEthereals

public void descend_precedingEthereals(TypedSubstantial<?> ec)

Calls match(TypedEthereal) for all preceding ethereals.

descend_followingEthereals

public void descend_followingEthereals(TypedSubstantial<?> ec)

Calls match(TypedEthereal) for all following ethereals.

match

public void match(TypedEthereal te)

Distinguishes between action(TypedComment) and action(TypedProcessingInstruction)

action

public void action(TypedComment c)

No-operation, can be overridden by the user, if required.

action

public void action(TypedProcessingInstruction p)

No-operation, can be overridden by the user, if required.

descend_attributes

public void descend_attributes(TypedElement<E,X> ec)

Calls action(TypedAttribute) for some attributes of the element.
If the global switch validating is true, then all attributes are visited which (a) had been assigned an explicit value when creating the document, or later by TypedAttribute.setValue(V), and (b) all those which have a default value in the DTD.
If the global switch validating is false, then only the attributes from case (a) are visited.

action

public void action(TypedAttribute a)

Calls match(TypedAttribute) for an attribute. May be overridden.

match

public void match(TypedAttribute ta)

Calls one of the overloaded action(X a) methods for the different subtypes of TypedAttribute.

action

public void action(CDataAttribute att)

Does nothing; can be overridden by the user, if required.

action

public void action(IdAttribute att)

Does nothing; can be overridden by the user, if required.

action

public void action(IdRefAttribute att)

Does nothing; can be overridden by the user, if required.

action

public void action(IdRefsAttribute att)

Does nothing; can be overridden by the user, if required.

action

public void action(NmTokenAttribute att)

Does nothing; can be overridden by the user, if required.

action

public void action(NmTokensAttribute att)

Does nothing; can be overridden by the user, if required.

action

public void action(SelectedIntegersAttribute att)

Does nothing; can be overridden by the user, if required.
