bool XFileNode::is_reference ( ) const [virtual, inherited]

Returns true if this node represents an indirect reference to an object defined previously in the file.

References are generally transparent, so in most cases you never need to call this, unless you actually need to differentiate between references and instances; you can simply use the reference node as if it were itself the object it references.

If this returns true, the node must be of type XFileDataNodeReference.

Reimplemented in XFileDataNodeReference.

Definition at line 185 of file xFileNode.cxx.

bool XFileTemplate::is_standard ( ) const [inline]

Returns true if this particular template is one of the "standard" templates defined by standardTemplates.x in this directory (and compiled into the binary), or false if it is a user-custom template.

Definition at line 26 of file xFileTemplate.I.

bool XFileNode::is_standard_object ( const string &  template_name) const [virtual, inherited]

Returns true if this node represents an instance of the standard template with the indicated name, or false otherwise.

This returns also returns true for references to standard objects.

If this returns true, the node must be of type XFileDataNode (it is either an XFileDataNodeTemplate or an XFileDataNodeReference).

Reimplemented in XFileDataNode.

Definition at line 220 of file xFileNode.cxx.

bool XFileTemplate::is_template_def ( ) const [virtual]

Returns true if this node represents the definition of some template.

This is the template definition, not an actual data object that represents an instance of the template. If the file strictly uses standard templates, the presence of template definitions is optional.

If this returns true, the node must be of type XFileTemplate.

Reimplemented from XFileNode.

Definition at line 78 of file xFileTemplate.cxx.

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 XFileTemplate::matches ( const XFileNode other) const [virtual]

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]
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.

const XFileParseDataList parse_data_list,
XFileNode::PrevData &  prev_data,
size_t &  index,
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.

Definition at line 284 of file xFileNode.cxx.

void XFileTemplate::set_open ( bool  open) [inline]

Sets whether the template is considered "open" or not.

If it is open (this flag is true), the set of options is ignored and the instances of this template may include any types of children. If it is closed (false), only the named types may be added.

Definition at line 40 of file xFileTemplate.I.

bool ReferenceCount::test_ref_count_integrity ( ) const [inline, inherited]
bool ReferenceCount::test_ref_count_nonzero ( ) const [inline, inherited]

Does some easy checks to make sure that the reference count isn't zero, or completely bogus.

Returns true if ok, false otherwise.

Referenced by CopyOnWritePointer::test_ref_count_nonzero().

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.
