void ReferenceCount::local_object | ( | ) | [inline, inherited] |
This function should be called, once, immediately after creating a new instance of some ReferenceCount-derived object on the stack.
This allows the object to be passed to functions that will increment and decrement the object's reference count temporarily, and it will prevent the object from being deleted (inappropriately), when the reference count returns to zero. It actually achieves this by setting a large positive value in the reference count field.

string XFileNode::make_nice_name | ( | const string & | str | ) | [static, inherited] |
Transforms the indicated egg name to a name that is acceptable for a node in the X File format.
Definition at line 557 of file xFileNode.cxx.
bool XFileNode::matches | ( | const XFileNode * | other | ) | const [virtual, inherited] |
Returns true if the node, particularly a template node, is structurally equivalent to the other node (which must be of the same type).
This checks data element types, but does not compare data element names.

void Namable::output | ( | ostream & | out | ) | const [inline, inherited] |
Outputs the Namable.
This function simply writes the name to the output stream; most Namable derivatives will probably redefine this.

bool XFile::read | ( | Filename | filename | ) |
Opens and reads the indicated .x file by name.
The nodes and templates defined in the file will be appended to the set of nodes already recorded, if any.
Returns true if the file is successfully read, false if there was an error (in which case the file might have been partially read).

bool XFile::read | ( | istream & | in, |
const string & | filename = string() |
||
) |
Parses the already-opened input stream for distributed class descriptions.
The filename parameter is optional and is only used when reporting errors.
The distributed classes defined in the file will be appended to the set of distributed classes already recorded, if any.
Returns true if the file is successfully read, false if there was an error (in which case the file might have been partially read).
void ReferenceCount::ref | ( | ) | const [inline, inherited] |
Explicitly increments the reference count.
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.

XFileNode::PrevData & | prev_data, | ||

size_t & | sub_index | ||
) | const [virtual, inherited] |
This is called on the template that defines an object, once the data for the object has been parsed.
It is responsible for identifying which component of the template owns each data element, and packing the data elements appropriately back into the object.
It returns true on success, or false on an error (e.g. not enough data elements, mismatched data type).
Reimplemented in XFileDataDef.

bool ReferenceCount::test_ref_count_integrity | ( | ) | const [inline, inherited] |
Does some easy checks to make sure that the reference count isn't completely bogus.
Returns true if ok, false otherwise.

bool ReferenceCount::unref | ( | ) | const [inline, virtual, inherited] |
Explicitly decrements the reference count.
Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic.) However, see the helper function unref_delete().
User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically.
This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it.
The return value is true if the new reference count is nonzero, false if it is zero.
