attList(void)

Construct a null attribute list.

attList(const attList& x)

Copy an attribute list by cloning all known attributes.

Parameters:

x - Attribute list to be copied.

virtual ~attList(void)

Delete all attribute values in the attribute list and clear the list.

attrib& addAttr(const std::string& name, const attrib& a)

The specified attribute value is cloned and added to the attribute list with the given name.

Returns:

reference to the attribute value entry.

Parameters:

name - Attribute name to be added.
a - Value of attribute to be added

attrib& repAttr(const std::string& name, const attrib& a)

The specified attribute value is used to replace the attribute with the given name.

Returns:

reference to the attribute value entry.

Parameters:

name - Attribute name to be replaced.
a - Replacement attribute value.

void remAttr(const std::string& name)

Remove the specified attribute from the list.

Parameters:

name - Name of attribute to be removed.

void clear(void)

Delete and destroy all attributes from the list.

bool empty(void) const

Test if the list has any attributes.

Returns:

true if the list is empty.

bool exists(const std::string& key) const

Test whether the named attribute is included in the list.

Returns:

true if the named attribute is in the list.

Parameters:

key - Name of attribute to search for.

const attrib& find(const std::string& key) const

Look for the specified attribute. Return a reference if it is found.

Returns:

Reference to the found attribute instance.

Parameters:

key - name of the attribute to be searched for.

Parameters:

x - List to be merged into the current list.

typedef AttrList::const_iterator const_attr_iter

Constant iterator for use in traversing the attribute list.

const_attr_iter begin(void) const

Fetch an iterator pointing to the start of the attribute list.

const_attr_iter end(void) const
