Detailed Description

This is the base class for many other classes, which defines very common virtual methods.

For convenience, none of them are abstract, but they must be defined, when they are needed, especially for containers.

~Object()

lout::object::Object::~Object ( )

Member Function Documentation

clone()

Object * lout::object::Object::clone ( )

virtual

Return an exact copy of the object.

Reimplemented in dw::core::EmptyIterator, dw::core::DeepIterator, dw::core::CharIterator, dw::Table::TableIterator, dw::Textblock::TextblockIterator, and dw::SimpleContainer::SimpleContainerIterator.

equals()

bool lout::object::Object::equals ( Object *  other )

virtual

Returns, whether two objects are equal.

The caller should ensure, that this and the object have the same class; this makes casting of "other" safe. Typically, an implementation should check this == other first, the caller can assume a fast implementation.

intoStringBuffer()

void lout::object::Object::intoStringBuffer ( misc::StringBuffer *  sb )

virtual

sizeOf()

size_t lout::object::Object::sizeOf ( )

virtual

Return the number of bytes, this object totally uses.

Reimplemented in lout::object::PairBase.

toString()

const char * lout::object::Object::toString

(

)

Use object::Object::intoStringBuffer to return a textual representation of the object.

The caller does not have to free the memory, object::Object is responsible for this.

Todo:

garbage!
