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

op	is the data-type to compare with this
level	is maximum level to descend when recursively comparing

Returns

negative, 0, positive depending on ordering of types

Reimplemented from Datatype.

References Datatype::compare(), 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

op	is the data-type to compare with this

Returns

negative, 0, positive depending on ordering of types

Reimplemented from Datatype.

References 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

s	is 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

el	is the XML element
typegrp	is 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

s	is the stream to write to

Reimplemented from Datatype.

References a_v_i(), Datatype::saveXmlBasic(), and wordsize.
