Class AttributeTokenizer

java.lang.Object
  org.apache.shale.clay.parser.AttributeTokenizer

public class AttributeTokenizer
extends Object

Tokenizes a portion of the document for attributes. The complete document is passed by reference and new Token offsets are created for the name and value of the discovered attributes.

Constructor Summary

AttributeTokenizer(StringBuffer buffer, int beginOffset, int endOffset, int lineNumber, int lineBeginOffset)
Overloaded constructor that is passed the complete document and the starting and ending offset of the node body within the document.

Method Summary

Iterator	iterator() Returns an instance of an Iterator that will enumerate attributes in the document where the attributes are represented by a AttributeTokenizer.AttributeEntry instance.
protected org.apache.shale.clay.parser.AttributeTokenizer.TokenOffset	nextToken(int startOffset, String endDelim, String otherDelim, boolean isKey) Returns the next Token given an startOffset and a endDelim.
protected void	parse(ArrayList tokenIndex) Builds an ArrayList of AttributeTokenizer.AttributeEntry instances identifying name and value pairs.

Constructor Detail

AttributeTokenizer

public AttributeTokenizer(StringBuffer buffer,
                          int beginOffset,
                          int endOffset,
                          int lineNumber,
                          int lineBeginOffset)

Overloaded constructor that is passed the complete document and the starting and ending offset of the node body within the document.

Parameters:

buffer - document

beginOffset - start index of node body in the document

endOffset - end index of node body in the document

lineNumber - line number of the node within the document

lineBeginOffset - index in the document that the line begins

Method Detail

parse

protected void parse(ArrayList tokenIndex)

Builds an ArrayList of AttributeTokenizer.AttributeEntry instances identifying name and value pairs.

Parameters:

tokenIndex - populated attribute offset of a beging node body

nextToken

protected org.apache.shale.clay.parser.AttributeTokenizer.TokenOffset nextToken(int startOffset,
                                                                                String endDelim,
                                                                                String otherDelim,
                                                                                boolean isKey)

Returns the next Token given an startOffset and a endDelim.

Parameters:

startOffset - begining offset in the document

endDelim - primary token delimiter

otherDelim - secondary token delimiter

isKey - looking for an attribute name not a value

Returns:

next token offset

iterator

public Iterator iterator()

Returns an instance of an Iterator that will enumerate attributes in the document where the attributes are represented by a AttributeTokenizer.AttributeEntry instance.

Returns:

returns a AttributeTokenizer.TokenIterator iterator.
