◆ var_diff()

var_diff	(	var_decl_sptr	first,
		var_decl_sptr	second,
		diff_sptr	type_diff,
		diff_context_sptr	ctxt = `diff_context_sptr()`
	)

protected

Constructor for var_diff.

Parameters

first	the first instance of var_decl to consider in the diff.
second	the second instance of var_decl to consider in the diff.
type_diff	the diff between types of the instances of var_decl.
ctxt	the diff context to use.

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 var_diff.

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

Reimplemented from diff.

Definition at line 3504 of file abg-comparison.cc.

◆ first_var()

var_decl_sptr first_var ( ) const

Getter for the first var_decl of the diff.

Returns: the first var_decl of the diff.

Definition at line 3548 of file abg-comparison.cc.

◆ get_pretty_representation()

const string & get_pretty_representation ( ) const

virtual

Returns: the pretty representation for this current instance of var_diff.

Reimplemented from diff.

Definition at line 3510 of file abg-comparison.cc.

◆ has_changes()

bool has_changes ( ) const

virtual

Return true iff the diff node has a change.

Returns: true iff the diff node has a change.

Implements diff.

Definition at line 3582 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 decl_diff_base.

Definition at line 3582 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 3604 of file abg-comparison.cc.

◆ second_var()

var_decl_sptr second_var ( ) const

Getter for the second var_decl of the diff.

Returns: the second var_decl of the diff.

Definition at line 3555 of file abg-comparison.cc.

◆ type_diff()

diff_sptr type_diff ( ) const

Getter for the diff of the types of the instances of var_decl.

Returns: the diff of the types of the instances of var_decl.

Definition at line 3563 of file abg-comparison.cc.

◆ compute_diff

var_diff_sptr compute_diff	(	const var_decl_sptr	first,
		const var_decl_sptr	second,
		diff_context_sptr	ctxt
	)

friend

Compute the diff between two instances of var_decl.

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

Parameters

first	the first var_decl to consider for the diff.
second	the second var_decl to consider for the diff.
ctxt	the diff context to use.

Returns: the resulting diff between the two var_decl.
