Query (ch.usi.si.seart:java-tree-sitter 1.5.0 API)

java.lang.Object
- ch.usi.si.seart.treesitter.Query

All Implemented Interfaces:

AutoCloseable
```
public class Query
extends Object
```
A query consists of one or more patterns, where each pattern is an S-expression that matches a certain set of nodes in a syntax tree. The query is associated with a particular language, and can only be run on syntax nodes parsed with that language. The expression to match a given node consists of a pair of parentheses containing two things: the node's type, and optionally, a series of other S-expressions that match the node's children. For example, this pattern would match any binary_expression node whose children are both number_literal nodes:
```
     (binary_expression (number_literal) (number_literal))
 
```
Children can also be omitted. For example, this would match any binary_expression where at least one of child is a string_literal node:
```
     (binary_expression (string_literal))
 
```
The underlying query value is immutable and can be safely shared between threads.
