Detailed Description

Datatype object representing executable code.

Sometimes, this holds the "function" being pointed to by a function pointer

Member Function Documentation

◆ compare()

int4 TypeCode::compare	(	const Datatype &	op,
		int4	level
	)		const

virtual

Compare for functional equivalence.

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.

◆ compareBasic()

int4 TypeCode::compareBasic ( const TypeCode * op ) const

Compare surface characteristics of two TypeCodes.

Compare basic characteristics of this with another TypeCode, not including the prototype

-1 or 1 if -this- and -op- are different in surface characteristics
0 if they are exactly equal and have no parameters
2 if they are equal on the surface, but additional comparisons must be made on parameters
Parameters

op is the other data-type to compare to

Returns
the comparison value

◆ compareDependency()

int4 TypeCode::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.

◆ getSubType()

Datatype * TypeCode::getSubType	(	uintb	off,
		uintb *	newoff
	)		const

virtual

Recover component data-type one-level down.

Given an offset into this data-type, return the component data-type at that offset. Also, pass back a "renormalized" offset suitable for recursize getSubType() calls: i.e. if the original offset hits the exact start of the sub-type, 0 is passed back. If there is no valid component data-type at the offset, return NULL and pass back the original offset

Parameters

off	is the offset into this data-type
newoff	is a pointer to the passed-back offset

Returns: a pointer to the component data-type or NULL

Reimplemented from Datatype.

◆ printRaw()

void TypeCode::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.

◆ restoreXml()

void TypeCode::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.

◆ saveXml()

void TypeCode::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.

◆ set()

void TypeCode::set	(	TypeFactory *	tfact,
		ProtoModel *	model,
		Datatype *	outtype,
		const vector< Datatype * > &	intypes,
		bool	dotdotdot,
		Datatype *	voidtype
	)

protected

Establish a function pointer.

Turn on the data-type's function prototype

Parameters

tfact	is the factory that owns this
model	is the prototype model
outtype	is the return type of the prototype
intypes	is the list of input parameters
dotdotdot	is true if the prototype takes variable arguments
voidtype	is the reference "void" data-type

◆ setProperties()

void TypeCode::setProperties	(	bool	isConstructor,
		bool	isDestructor
	)

Set additional function properties.

Assuming this has an underlying function prototype, set some of its boolean properties

Parameters

isConstructor	toggles whether the function is a constructor
isDestructor	toggles whether the function is a destructor
