Methods Summary
public java.lang.StringgetBaseSystemId()
Returns the base system identifier of the currently scanned entity, or null if none is available.

        return (fCurrentEntity != null && fCurrentEntity.entityLocation != null) ? fCurrentEntity.entityLocation.getExpandedSystemId() : null;
    
public intgetColumnNumber()
Return the column number where the current document event ends.

Warning: The return value from the method is intended only as an approximation for the sake of error reporting; it is not intended to provide sufficient information to edit the character content of the original XML document.

The return value is an approximation of the column number in the document entity or external parsed entity where the markup triggering the event appears.

If possible, the SAX driver should provide the line position of the first character after the text associated with the document event.

If possible, the SAX driver should provide the line position of the first character after the text associated with the document event. The first column in each line is column 1.

return
The column number, or -1 if none is available.

        if (fCurrentEntity != null) {
            if (fCurrentEntity.isExternal()) {
                return fCurrentEntity.columnNumber;
            }
            else {
                // ask current entity to find appropriate column number
                return fCurrentEntity.getColumnNumber();
            }
        }

        return -1;
    
public java.lang.StringgetEncoding()
Returns the encoding of the current entity. Note that, for a given entity, this value can only be considered final once the encoding declaration has been read (or once it has been determined that there is no such declaration) since, no encoding having been specified on the XMLInputSource, the parser will make an initial "guess" which could be in error.

        if (fCurrentEntity != null) {
            if (fCurrentEntity.isExternal()) {
                return fCurrentEntity.encoding;
            }
            else {
                // ask current entity to find appropriate column number
                return fCurrentEntity.getEncoding();
            }
        }

        return null;
    
public java.lang.StringgetExpandedSystemId()
Return the expanded system identifier for the current document event.

The return value is the expanded system identifier of the document entity or of the external parsed entity in which the markup triggering the event appears.

If the system identifier is a URL, the parser must resolve it fully before passing it to the application.

return
A string containing the expanded system identifier, or null if none is available.

        if (fCurrentEntity != null) {
            if (fCurrentEntity.entityLocation != null &&
                    fCurrentEntity.entityLocation.getExpandedSystemId() != null ) {
                return fCurrentEntity.entityLocation.getExpandedSystemId();
            }
            else {
                // get the current entity to return something appropriate:
                return fCurrentEntity.getExpandedSystemId();
            }
        }
        return null;
    
public intgetLineNumber()
Return the line number where the current document event ends.

Warning: The return value from the method is intended only as an approximation for the sake of error reporting; it is not intended to provide sufficient information to edit the character content of the original XML document.

The return value is an approximation of the line number in the document entity or external parsed entity where the markup triggering the event appears.

If possible, the SAX driver should provide the line position of the first character after the text associated with the document event. The first line in the document is line 1.

return
The line number, or -1 if none is available.

        if (fCurrentEntity != null) {
            if (fCurrentEntity.isExternal()) {
                return fCurrentEntity.lineNumber;
            }
            else {
                // ask the current entity to return something appropriate:
                return fCurrentEntity.getLineNumber();
            }
        }

        return -1;

    
public java.lang.StringgetLiteralSystemId()
Return the literal system identifier for the current document event.

The return value is the literal system identifier of the document entity or of the external parsed entity in which the markup triggering the event appears.

return
A string containing the literal system identifier, or null if none is available.

        if (fCurrentEntity != null) {
            if (fCurrentEntity.entityLocation != null &&
                    fCurrentEntity.entityLocation.getLiteralSystemId() != null ) {

                return fCurrentEntity.getLiteralSystemId();
            }
        }
        return null;
    
public java.lang.StringgetPublicId()
Return the public identifier for the current document event.

The return value is the public identifier of the document entity or of the external parsed entity in which the markup triggering the event appears.

return
A string containing the public identifier, or null if none is available.

        return (fCurrentEntity != null && fCurrentEntity.entityLocation != null) ? fCurrentEntity.entityLocation.getPublicId() : null;
    
public booleanisExternal()
Returns true if the current entity being scanned is external.

        return fCurrentEntity.isExternal();
    
final booleanload(int offset, boolean changeEntity)
Loads a chunk of text.

param
offset The offset into the character buffer to read the next batch of characters.
param
changeEntity True if the load should change entities at the end of the entity, otherwise leave the current entity in place and the entity boundary will be signaled by the return value.

Returns true if the entity changed as a result of this load operation.

Scans a range of parsed character data, setting the fields of the XMLString structure, appropriately.

Returns the next character on the input, if known. This value may be -1 but this does note designate end of file.

public booleanscanData(java.lang.String delimiter, com.sun.org.apache.xerces.internal.util.XMLStringBuffer buffer)
Scans a range of character data up to the specified delimiter, setting the fields of the XMLString structure, appropriately.

Note: The characters are consumed.

Note: This assumes that the internal buffer is at least the same size, or bigger, than the length of the delimiter and that the delimiter contains at least one character.

Note: This method does not guarantee to return the longest run of character data. This method may return before the delimiter due to reaching the end of the input buffer or any other reason.

Note: The fields contained in the XMLString structure are not guaranteed to remain valid upon subsequent calls to the entity scanner. Therefore, the caller is responsible for immediately using the returned character data or making a copy of the character data.

param
delimiter The string that signifies the end of the character data to be scanned.
param
data The data structure to fill.
return
Returns true if there is more data to scan, false otherwise.
throws
IOException Thrown if i/o error occurs.
throws
EOFException Thrown on end of file.

public intscanLiteral(int quote, com.sun.org.apache.xerces.internal.xni.XMLString content)
Scans a range of attribute value data, setting the fields of the XMLString structure, appropriately.

Note: The characters are consumed.

Note: This method does not guarantee to return the longest run of attribute value data. This method may return before the quote character due to reaching the end of the input buffer or any other reason.

Note: The fields contained in the XMLString structure are not guaranteed to remain valid upon subsequent calls to the entity scanner. Therefore, the caller is responsible for immediately using the returned character data or making a copy of the character data.

param
quote The quote character that signifies the end of the attribute value data.
param
content The content structure to fill.
return
Returns the next character on the input, if known. This value may be -1 but this does note designate end of file.
throws
IOException Thrown if i/o error occurs.
throws
EOFException Thrown on end of file.

public booleanskipDeclSpaces()
Skips space characters appearing immediately on the input that would match non-terminal S (0x09, 0x0A, 0x0D, 0x20) before end of line normalization is performed. This is useful when scanning structures such as the XMLDecl and TextDecl that can only contain US-ASCII characters.

Note: The characters are consumed only if they would match non-terminal S before end of line normalization is performed.

return
Returns true if at least one space character was skipped.
throws
IOException Thrown if i/o error occurs.
