Attrs

public class Attrs extends Object implements Attributes
SAX Attributes interface implementation.

Fields Summary
String[]
mItems
Attributes string array. Each individual attribute is reprecented by four strings: namespace URL(+0), qname(+1), local name(+2), value(+3), type(+4). In order to find attribute by the attrubute index, the attribute index MUST be multiplied by 8. The result will point to the attribute namespace URL.
private char
mLength
Number of attributes in the attributes string array.
Constructors Summary
Attrs()
Constructor.

		//		The default number of attributies capacity is 8.
		mItems	= new String[(8 << 3)];
Methods Summary
public intgetIndex(java.lang.String qName)
Look up the index of an attribute by XML 1.0 qualified name.

param
qName The qualified (prefixed) name.
return
The index of the attribute, or -1 if it does not appear in the list.

		char	len	= mLength;
		char	idx	= 0;
		while (idx < len) {
			if (getQName(idx).equals(qName))
				return idx;
			idx++;
		}
		return -1;
public intgetIndex(java.lang.String uri, java.lang.String localName)
Look up the index of an attribute by Namespace name.

param
uri The Namespace URI, or the empty string if the name has no Namespace URI.
param
localName The attribute's local name.
return
The index of the attribute, or -1 if it does not appear in the list.

		char	len	= mLength;
		char	idx	= 0;
		while (idx < len) {
			if ((mItems[idx << 3]).equals(uri) &&
				mItems[(idx << 3) + 2].equals(localName))
				return idx;
			idx++;
		}
		return -1;
public intgetLength()
Return the number of attributes in the list.

Once you know the number of attributes, you can iterate through the list.

return
The number of attributes in the list.

#getLocalName(int)

#getQName(int)

#getValue(int)

		return mLength;
public java.lang.StringgetLocalName(int index)
Look up an attribute's local name by index.

param
index The attribute index (zero-based).
return
The local name, or the empty string if Namespace processing is not being performed, or null if the index is out of range.
see
#getLength

		return ((index >= 0) && (index < mLength))? 
			(mItems[(index << 3) + 2]):
			null;
public java.lang.StringgetQName(int index)
Look up an attribute's XML 1.0 qualified name by index.

param
index The attribute index (zero-based).
return
The XML 1.0 qualified name, or the empty string if none is available, or null if the index is out of range.
see
#getLength

		if ((index < 0) || (index >= mLength))
			return null;
		return mItems[(index << 3) + 1];
public java.lang.StringgetType(java.lang.String uri, java.lang.String localName)
Look up an attribute's type by Namespace name.

See {@link #getType(int) getType(int)} for a description of the possible types.

param
uri The Namespace URI, or the empty String if the name has no Namespace URI.
param
localName The local name of the attribute.
return
The attribute type as a string, or null if the attribute is not in the list or if Namespace processing is not being performed.

		int	idx	= getIndex(uri, localName);
		return (idx >= 0)? (mItems[(idx << 3) + 4]): null;
public java.lang.StringgetType(java.lang.String qName)
Look up an attribute's type by XML 1.0 qualified name.

See {@link #getType(int) getType(int)} for a description of the possible types.

param
qName The XML 1.0 qualified name.
return
The attribute type as a string, or null if the attribute is not in the list or if qualified names are not available.

		int	idx	= getIndex(qName);
		return (idx >= 0)? (mItems[(idx << 3) + 4]): null;
public java.lang.StringgetType(int index)
Look up an attribute's type by index.

The attribute type is one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", or "NOTATION" (always in upper case).

If the parser has not read a declaration for the attribute, or if the parser does not report attribute types, then it must return the value "CDATA" as stated in the XML 1.0 Recommentation (clause 3.3.3, "Attribute-Value Normalization").

For an enumerated attribute that is not a notation, the parser will report the type as "NMTOKEN".

param
index The attribute index (zero-based).
return
The attribute's type as a string, or null if the index is out of range.
see
#getLength

		return ((index >= 0) && (index < (mItems.length >> 3)))? 
			(mItems[(index << 3) + 4]): 
			null;
public java.lang.StringgetURI(int index)
Look up an attribute's Namespace URI by index.

param
index The attribute index (zero-based).
return
The Namespace URI, or the empty string if none is available, or null if the index is out of range.
see
#getLength

		return ((index >= 0) && (index < mLength))? 
			(mItems[index << 3]): 
			null;
public java.lang.StringgetValue(java.lang.String uri, java.lang.String localName)
Look up an attribute's value by Namespace name.

See {@link #getValue(int) getValue(int)} for a description of the possible values.

param
uri The Namespace URI, or the empty String if the name has no Namespace URI.
param
localName The local name of the attribute.
return
The attribute value as a string, or null if the attribute is not in the list.

		int	idx	= getIndex(uri, localName);
		return (idx >= 0)? (mItems[(idx << 3) + 3]): null;
public java.lang.StringgetValue(java.lang.String qName)
Look up an attribute's value by XML 1.0 qualified name.

See {@link #getValue(int) getValue(int)} for a description of the possible values.

param
qName The XML 1.0 qualified name.
return
The attribute value as a string, or null if the attribute is not in the list or if qualified names are not available.

		int	idx	= getIndex(qName);
		return (idx >= 0)? (mItems[(idx << 3) + 3]): null;
public java.lang.StringgetValue(int index)
Look up an attribute's value by index.

If the attribute value is a list of tokens (IDREFS, ENTITIES, or NMTOKENS), the tokens will be concatenated into a single string with each token separated by a single space.

param
index The attribute index (zero-based).
return
The attribute's value as a string, or null if the index is out of range.
see
#getLength

		return ((index >= 0) && (index < mLength))? 
			(mItems[(index << 3) + 3]):
			null;
voidsetLength(char length)
Sets up the number of attributes and ensure the capacity of the attribute string array.

param
length The number of attributes in the object.

		if (length > ((char)(mItems.length >> 3))) {
			mItems	= new String[length << 3];
		}
		mLength	= length;
