SchemaElement

public SchemaElement()

getStructureType

public abstract short getStructureType()

Returns the type of this Schema Structure

Returns:

the type of this Schema Structure. Uses the codes defined by static constants in this module, for example ELEMENT or WILDCARD_ATTRIBUTE.

getSystemId

public java.lang.String getSystemId()

Get the system identifier (URI) of the schema module (XML document) containing the definition of this component.

Specified by:

getSystemId in interface javax.xml.transform.SourceLocator

Returns:

the URI of the containing module.

getPublicId

public java.lang.String getPublicId()

Get the public ID of the containing module, if known.

Specified by:

getPublicId in interface javax.xml.transform.SourceLocator

Returns:

This information is not currently maintained, the method always returns null.

getLineNumber

public int getLineNumber()

Get the line number of the element defining this schema component, within its module. This will be as delivered by the SAX2 parser: that is, the line number of an element is generally the line number on which its start tag ends.

Specified by:

getLineNumber in interface javax.xml.transform.SourceLocator

Returns:

the line number where the relevant element can be found.

getColumnNumber

public int getColumnNumber()

Get the column number of the element defining this schema component.

Specified by:

getColumnNumber in interface javax.xml.transform.SourceLocator

Returns:

-1: this information is not maintained.

setLocator

public void setLocator(javax.xml.transform.SourceLocator locator)

Set the location information for this schema component. For internal use.

Parameters:

locator - the location information.
