Properties

AST-children of CALL nodes have an argument index, that is used to match call-site arguments with callee parameters. Explicit parameters are numbered from 1 to N, while index 0 is reserved for implicit self / this parameter. CALLs without implicit parameter therefore have arguments starting with index 1. AST-children of BLOCK nodes may have an argument index as well; in this case, the last argument index determines the return expression of a BLOCK expression. If the PARAMETER_NAME field is set, then the ARGUMENT_INDEX field is ignored. It is suggested to set it to -1.

For calls involving named parameters, the ARGUMENT_NAME field holds the name of the parameter initialized by the expression. For all other calls, this field is unset.

This field holds the code snippet that the node represents.

This optional fields provides the column number of the program construct represented by the node.

References to other nodes. This is not a real property; it exists here for the sake of proto serialization only. valueType and cardinality are meaningless.

Type hint for the dynamic type. These are observed to be verifiable at runtime.

This optional field provides the line number of the program construct represented by the node.

This integer indicates the position of the node among its siblings in the AST. The left-most child has an order of 0.

AST node type name emitted by parser.

Similar to DYNAMIC_TYPE_HINT_FULL_NAME, but that this makes no guarantee that types within this property are correct. This property is used to capture observations between node interactions during a 'may-analysis'.

This field contains the fully-qualified static type name of the program construct represented by a node. It is the name of an instantiated type, e.g., java.util.List<Integer>, rather than java.util.List[T]. If the type cannot be determined, this field should be set to the empty string.
