Struct umm::java::Parser

pub struct Parser {
    code: String,
    _tree: Option<Tree>,
    lang: Language,
}

A struct that wraps a tree-sitter parser object and source code

Fields

code: String

the source code being parsed

_tree: Option<Tree>

the parse tree

lang: Language

the tree-sitter java grammar language

Implementations

impl Parser

pub fn new(source_code: String, lang: Language) -> Result<Self>

Returns a new parser object

• source_code: the source code to be parsed
• lang: the tree-sitter grammar to use

pub fn new_script( source_code: String, lang: Language ) -> Result<Self, Box<EvalAltResult>>

Macro generated variant of #fn_name that returns EvalAltResult. This allows the function to be used in scripts.

pub fn code(&mut self) -> String

A getter for parser’s source code

pub fn set_code(&mut self, code: String)

A setter for parser’s source code

pub fn query(&self, q: &str) -> Result<Vec<HashMap<String, String>>>

Applies a tree sitter query and returns the result as a collection of HashMaps

• q: the tree-sitter query to be applied

pub fn query_mut_script( &mut self, q: &str ) -> Result<Vec<HashMap<String, String>>, Box<EvalAltResult>>

Macro generated variant of #fn_name that returns EvalAltResult. This allows the function to be used in scripts.
