PHP Class Phan\Analysis\AssignmentVisitor

Inheritance: extends Phan\AST\Visitor\KindVisitorImplementation

Public Methods

Method	Description
__construct ( CodeBase $code_base, Context $context, ast\Node $assignment_node, UnionType $right_type, boolean $is_dim_assignment = false )
visit ( ast\Node $node ) : Context	Default visitor for node kinds that do not have an overriding method
visitArray ( ast\Node $node ) : Context	This happens for code like the following list($a) = [1, 2, 3];
visitCall ( ast\Node $node ) : Context	The following is an example of how this'd happen.
visitDim ( ast\Node $node ) : Context
visitList ( ast\Node $node ) : Context
visitMethodCall ( ast\Node $node ) : Context	The following is an example of how this'd happen.
visitProp ( ast\Node $node ) : Context
visitStaticProp ( ast\Node $node ) : Context
visitVar ( ast\Node $node ) : Context

Method	Description
analyzeSuperglobalDim ( ast\Node $node, string $variable_name ) : Context	Analyze an assignment where $variable_name is a superglobal, and return the new context.

public __construct ( CodeBase $code_base, Context $context, ast\Node $assignment_node, UnionType $right_type, boolean $is_dim_assignment = false )
$code_base	Phan\CodeBase	The global code base we're operating within
$context	Phan\Language\Context	The context of the parser at the node for which we'd like to determine a type
$assignment_node	ast\Node	The AST node containing the assignment
$right_type	Phan\Language\UnionType	The type of the element on the right side of the assignment
$is_dim_assignment	boolean	True if this assignment is to an array parameter such as in `$foo[3] = 42`. We need to know this in order to decide if we're replacing the union type or if we're adding a type to the union type.

Default visitor for node kinds that do not have an overriding method

public visit ( ast\Node $node ) : Context
$node	ast\Node	A node to parse
return	Phan\Language\Context	A new or an unchanged context resulting from parsing the node

This happens for code like the following list($a) = [1, 2, 3];

public visitArray ( ast\Node $node ) : Context
$node	ast\Node	A node to parse
return	Phan\Language\Context	A new or an unchanged context resulting from parsing the node

php function f() { return [ 24 ]; } f()[1] = 42;

public visitCall ( ast\Node $node ) : Context
$node	ast\Node	A node to parse
return	Phan\Language\Context	A new or an unchanged context resulting from parsing the node

public visitDim ( ast\Node $node ) : Context
$node	ast\Node	A node to parse
return	Phan\Language\Context	A new or an unchanged context resulting from parsing the node

public visitList ( ast\Node $node ) : Context
$node	ast\Node	A node to parse
return	Phan\Language\Context	A new or an unchanged context resulting from parsing the node

php class C { function f() { return [ 24 ]; } } (new C)->f()[1] = 42;

public visitMethodCall ( ast\Node $node ) : Context
$node	ast\Node	A node to parse
return	Phan\Language\Context	A new or an unchanged context resulting from parsing the node

public visitProp ( ast\Node $node ) : Context
$node	ast\Node	A node to parse
return	Phan\Language\Context	A new or an unchanged context resulting from parsing the node

public visitStaticProp ( ast\Node $node ) : Context
$node	ast\Node	A node to parse
return	Phan\Language\Context	A new or an unchanged context resulting from parsing the node

public visitVar ( ast\Node $node ) : Context
$node	ast\Node	A node to parse
return	Phan\Language\Context	A new or an unchanged context resulting from parsing the node
