TypeHandle is the identifier used to differentiate C++ class types.
Definition: typeHandle.h:81
This is a node which contains all of the data elements defined by a template.
virtual void write_data(std::ostream &out, int indent_level, const char *separator) const
Writes a suitable representation of this node to an .x file in text mode.
bool finalize_parse_data()
Processes all of the data elements added by add_parse_*(), checks them for syntactic and semantic cor...
void add_parse_double(PTA_double double_list)
Adds the indicated list of doubles as a data element encountered in the parser.
virtual bool add_element(XFileDataObject *element)
Adds the indicated element as a nested data element, if this data object type supports it.
void zero_fill()
Fills the data node with zero-valued elements appropriate to the template.
virtual bool is_complex_object() const
Returns true if this kind of data object is a complex object that can hold nested data elements,...
void add_parse_int(PTA_int int_list)
Adds the indicated list of ints as a data element encountered in the parser.
virtual void write_text(std::ostream &out, int indent_level) const
Writes a suitable representation of this node to an .x file in text mode.
void add_parse_string(const std::string &str)
Adds the indicated string as a data element encountered in the parser.
This is an abstract base class for an XFileNode which is also an XFileDataObject.
Definition: xFileDataNode.h:33
The abstract base class for a number of different types of data elements that may be stored in the X ...
A container for a pvector of the above objects.
A template definition in the X file.
Definition: xFileTemplate.h:27
This represents the complete contents of an X file (file.x) in memory.
Definition: xFile.h:32
