Description

~AttributeContainer [destructor] [virtual]

Destroy this object.

hasValue [virtual]

Return true if a attribute having the specified value exists in this object, and false otherwise.

print [virtual]

Format this object to the specified output stream at the (absolute value of) the optionally specified indentation level and return a reference to stream. If level is specified, optionally specify spacesPerLevel, the number of spaces per indentation level for this and all of its nested objects. If level is negative, suppress indentation of the first line. If spacesPerLevel is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by level). If stream is not valid on entry, this operation has no effect.

visitAttributes [virtual]

Invoke the specified visitor function for all attributes in this container.
