## Detailed Description

A template definition in the X file.

This defines the data structures that may be subsequently read.

Definition at line 27 of file xFileTemplate.h.

## Constructor & Destructor Documentation

## ◆ XFileTemplate()

XFileTemplate::XFileTemplate | ( | XFile * | x_file,
|  | const std::string & | name,
|  | const WindowsGuid & | guid )

## ◆ ~XFileTemplate()

XFileTemplate::~XFileTemplate | ( |  | ) |
| virtual

## Member Function Documentation

## ◆ add_option()

void XFileTemplate::add_option | ( | XFileTemplate * | option | ) |
| inline

Adds a new type to the list of allowable types of child nodes for an instance of this template.

Definition at line 50 of file xFileTemplate.I.

## ◆ clear()

void XFileTemplate::clear | ( |  | ) |
| virtual

Removes all children from the node, and otherwise resets it to its initial state.

Reimplemented from XFileNode.

Definition at line 72 of file xFileTemplate.cxx.

References XFileNode::clear().

## ◆ force_init_type()

virtual TypeHandle XFileTemplate::force_init_type | ( |  | ) |
| inline virtual

Definition at line 71 of file xFileTemplate.h.

## ◆ get_class_type()

static TypeHandle XFileTemplate::get_class_type | ( |  | ) |
| inline static

Definition at line 60 of file xFileTemplate.h.

## ◆ get_guid()

const WindowsGuid & XFileTemplate::get_guid | ( |  | ) | const
| virtual

Returns the GUID associated with this template.

Reimplemented from XFileNode.

Definition at line 50 of file xFileTemplate.cxx.

Referenced by write_text().

## ◆ get_num_options()

int XFileTemplate::get_num_options | ( |  | ) | const

Definition at line 58 of file xFileTemplate.I.

## ◆ get_open()

bool XFileTemplate::get_open | ( |  | ) | const
| inline

Returns 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.

## ◆ get_option()

XFileTemplate * XFileTemplate::get_option | ( | int | n | ) | const
| inline

Returns the nth template on the options list.

Definition at line 66 of file xFileTemplate.I.

## ◆ get_type()

virtual TypeHandle XFileTemplate::get_type | ( |  | ) | const

Reimplemented from XFileNode.

Definition at line 68 of file xFileTemplate.h.

## ◆ has_guid()

## ◆ is_standard()

bool XFileTemplate::is_standard | ( |  | ) | const

Definition at line 19 of file xFileTemplate.I.

## ◆ is_template_def()

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 63 of file xFileTemplate.cxx.

## ◆ matches()

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.

Reimplemented from XFileNode.

Referenced by XFile::find_template(), and XFile::find_template().

## ◆ set_open()

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 30 of file xFileTemplate.I.

## ◆ write_text()

void XFileTemplate::write_text | ( | std::ostream & | out,
|  | int | indent_level ) const
| virtual
