public class VNsInputElementStack

extends NsInputElementStack

Sub-class of NsInputElementStack that adds basic support for (DTD-based) validation of XML documents.

Field Summary

protected java.util.Map

mElemSpecs Map that contains element specifications from DTD; null for non-validating parsers.

Constructor Summary

VNsInputElementStack(int initialSize, java.lang.String prefixXml, java.lang.String prefixXmlns, boolean normAttrs)

Method Summary

java.lang.String	getAttributeType(int index) Input element stack has to ask validator about this data; validator keeps track of attribute declarations for the current element
int	getIdAttributeIndex() Default implementation just indicates it does not know of such attributes; this because that requires DTD information that only some implementations have.
int	getNotationAttributeIndex() Default implementation just indicates it does not know of such attributes; this because that requires DTD information that only some implementations have.
int	pop() Method called by the stream reader to remove the topmost (start) element from the stack; called when an end element is encountered during parsing.
int	resolveElem(boolean internNsURIs) Method called to update information about top of the stack, with attribute information passed in.
void	setElementSpecs(java.util.Map elemSpecs, SymbolTable symbols, boolean normAttrs, java.util.Map generalEntities) Method called by the validating stream reader if and when it has read internal and/or external DTD subsets, and has thus parsed element specifications.

Field Detail

mElemSpecs

protected java.util.Map mElemSpecs

Map that contains element specifications from DTD; null for non-validating parsers.

Constructor Detail

VNsInputElementStack

public VNsInputElementStack(int initialSize,
                            java.lang.String prefixXml,
                            java.lang.String prefixXmlns,
                            boolean normAttrs)

Method Detail

setElementSpecs

public void setElementSpecs(java.util.Map elemSpecs,
                            SymbolTable symbols,
                            boolean normAttrs,
                            java.util.Map generalEntities)

Method called by the validating stream reader if and when it has read internal and/or external DTD subsets, and has thus parsed element specifications.

Overrides:

setElementSpecs in class InputElementStack

pop

public int pop()
        throws WstxException

Description copied from class: InputElementStack

Method called by the stream reader to remove the topmost (start) element from the stack; called when an end element is encountered during parsing.

Overrides:

pop in class NsInputElementStack

Returns:

Validation state that should be effective for the parent element state

Throws:

WstxException

resolveElem

public int resolveElem(boolean internNsURIs)
                throws WstxException

Method called to update information about top of the stack, with attribute information passed in. Will resolve namespace references, and update namespace stack with information.

Overrides:

resolveElem in class NsInputElementStack

Returns:

Validation state that should be effective for the fully resolved element context

Throws:

WstxException

getAttributeType

public java.lang.String getAttributeType(int index)

Input element stack has to ask validator about this data; validator keeps track of attribute declarations for the current element

Overrides:

getAttributeType in class InputElementStack

getIdAttributeIndex

public int getIdAttributeIndex()

Description copied from class: InputElementStack

Default implementation just indicates it does not know of such attributes; this because that requires DTD information that only some implementations have.

Specified by:

getIdAttributeIndex in interface AttributeInfo

Overrides:

getIdAttributeIndex in class InputElementStack

getNotationAttributeIndex

public int getNotationAttributeIndex()

Description copied from class: InputElementStack

Default implementation just indicates it does not know of such attributes; this because that requires DTD information that only some implementations have.

Specified by:

getNotationAttributeIndex in interface AttributeInfo

Overrides:

getNotationAttributeIndex in class InputElementStack
