as.field.decl: Find appropriate sub-node
In omegahat/RGCCTranslationUnit: R interface to GCC source code information

Description Usage Arguments Value Author(s) References See Also

These functions attempt to search the given node in a sensible manner to find the relevant sub-node as indicated by the name of the function. Fror example, as.parm.decl will search a GCC::Node::function_decl and find the first GCC::Node::parm_decl node, if it exists.

These are meant as convenience functions to find map from a high-level object to the first node of the target type so that we can then iterate over the nodes, starting at that one.

as.field.decl(x, follow = TRUE, acceptableTypes =
                 c("GCC::Node::field_decl", "GCC::Node::var_decl",
                 "GCC::Node::const_decl"))
as.record.type(x, stopOnFail = TRUE)
as.parm.decl(x)
as.type.decl(x)

`x`	a reference to a Perl GCC::Node object obtained from parsing the translation unit.
`stopOnFail`	a logical value indicating whether to generate an error if the node could not be mapped to a record_type or simply return `NULL`
`follow`	(logical) controls whether to jump from the given node to one of its elements to find the definition of the field.
`acceptableTypes`	a character vector giving the names of the classes that are legitimate nodes for a field.
