Constructor & Destructor Documentation

◆ pointer_diff()

pointer_diff	(	pointer_type_def_sptr	first,
		pointer_type_def_sptr	second,
		diff_sptr	underlying,
		diff_context_sptr	ctxt = `diff_context_sptr()`
	)

protected

Constructor for a pointer_diff.

Parameters

first	the first pointer to consider for the diff.
second	the secon pointer to consider for the diff.
ctxt	the diff context to use.

Definition at line 3652 of file abg-comparison.cc.

Member Function Documentation

◆ chain_into_hierarchy()

void chain_into_hierarchy ( )

virtual

Populate the vector of children node of the diff base type sub-object of this instance of pointer_diff.

The children node can then later be retrieved using diff::children_node().

Reimplemented from diff.

Definition at line 3642 of file abg-comparison.cc.

◆ first_pointer()

const pointer_type_def_sptr first_pointer ( ) const

Getter for the first subject of a pointer diff.

Returns: the first pointer considered in this pointer diff.

Definition at line 3664 of file abg-comparison.cc.

◆ get_pretty_representation()

const string & get_pretty_representation ( ) const

virtual

Returns: the pretty represenation for the current instance of pointer_diff.

Reimplemented from diff.

Definition at line 3677 of file abg-comparison.cc.

◆ has_changes()

bool has_changes ( ) const

virtual

Return true iff the current diff node carries a change.

Returns: true iff the current diff node carries a change.

Implements diff.

Definition at line 3696 of file abg-comparison.cc.

◆ has_local_changes()

enum change_kind has_local_changes ( ) const

virtual

Returns: the kind of local change carried by the current diff node. The value returned is zero if the current node carries no local change.

Implements type_diff_base.

Definition at line 3696 of file abg-comparison.cc.

◆ report()

void report	(	ostream &	out,
		const string &	indent = `""`
	)		const

virtual

Report the diff in a serialized form.

Parameters

out	the stream to serialize the diff to.
indent	the prefix to use for the indentation of this serialization.

Implements diff.

Definition at line 3735 of file abg-comparison.cc.

◆ second_pointer()

const pointer_type_def_sptr second_pointer ( ) const

Getter for the second subject of a pointer diff.

Returns: the second pointer considered in this pointer diff.

Definition at line 3671 of file abg-comparison.cc.

◆ underlying_type_diff() [1/2]

diff_sptr underlying_type_diff ( ) const

Getter for the diff between the pointed-to types of the pointers of this diff.

Returns: the diff between the pointed-to types.

Definition at line 3716 of file abg-comparison.cc.

◆ underlying_type_diff() [2/2]

void underlying_type_diff ( const diff_sptr d )

Setter for the diff between the pointed-to types of the pointers of this diff.

Parameters

d	the new diff between the pointed-to types of the pointers of this diff.

Definition at line 3725 of file abg-comparison.cc.

◆ compute_diff

pointer_diff_sptr compute_diff	(	pointer_type_def_sptr	first,
		pointer_type_def_sptr	second,
		diff_context_sptr	ctxt
	)

friend

Compute the diff between between two pointers.

Note that the two types must have been created in the same environment, otherwise, this function aborts.

Parameters

first	the pointer to consider for the diff.
second	the pointer to consider for the diff.

Returns: the resulting diff between the two pointers.

Parameters

ctxt	the diff context to use.
