Detailed Description

Datatype object representing a pointer.

Member Function Documentation

◆ compare()

int4 TypePointer::compare ( const Datatype op,
int4  level 
) const
virtual

Compare for functional equivalence.

Compare this with another data-type. 0 (equality) means the data-types are functionally equivalent (even if names differ) Smaller types come earlier. More specific types come earlier.

Parameters
opis the data-type to compare with this
levelis maximum level to descend when recursively comparing
Returns
negative, 0, positive depending on ordering of types

Reimplemented from Datatype.

References Datatype::compare(), Datatype::getId(), Datatype::getMetatype(), Datatype::getSize(), Datatype::metatype, ptrto, Datatype::size, and wordsize.

◆ compareDependency()

int4 TypePointer::compareDependency ( const Datatype op) const
virtual

Compare for storage in tree structure.

Ordering of data-types for the main TypeFactory container. Comparison only goes down one-level in the component structure, before just comparing pointers.

Parameters
opis the data-type to compare with this
Returns
negative, 0, positive depending on ordering of types

Reimplemented from Datatype.

References Datatype::getMetatype(), Datatype::getSize(), Datatype::metatype, ptrto, Datatype::size, and wordsize.

◆ printRaw()

void TypePointer::printRaw ( ostream &  s) const
virtual

Print a description of the type to stream.

Print a raw description of the type to stream. Intended for debugging. Not intended to produce parsable C.

Parameters
sis the output stream

Reimplemented from Datatype.

References Datatype::printRaw(), and ptrto.

◆ restoreXml()

void TypePointer::restoreXml ( const Element el,
TypeFactory typegrp 
)
protectedvirtual

Restore data-type from XML.

Restore a Datatype object from an XML element

Parameters
elis the XML element
typegrpis the underlying TypeFactory that will hold the new object

Reimplemented from Datatype.

Referenced by TypeFactory::restoreXmlTypeNoRef().

◆ saveXml()

void TypePointer::saveXml ( ostream &  s) const
virtual

Serialize the data-type to XML.

Write out a formal description of the data-type as an XML <type> tag. For composite data-types, the description goes down one level, describing the component types only by reference.

Parameters
sis the stream to write to

Reimplemented from Datatype.

References Datatype::saveXmlBasic(), and wordsize.
