Class JavaParser

java.lang.Object

gw.internal.gosu.parser.java.compiler.JavaParser

All Implemented Interfaces:

IJavaParser

public class JavaParser
extends Object
implements IJavaParser

A tool for parsing and compiling Java source. A notable feature of this tool is its ability to compile Java sources that reference and invoke Gosu types. This feature enables bi-directional Java interop with Gosu.

parseText

public boolean parseText(String src,
                         List<com.sun.source.tree.CompilationUnitTree> trees,
                         java.util.function.Consumer<com.sun.source.util.SourcePositions> sourcePositions,

compile

public ClassJavaFileObject compile(String fqn,
                                   Iterable<String> options,
                                   DiagnosticCollector<JavaFileObject> errorHandler)

Compiles specified Java class name. Maintains cache between calls to this method, therefore subsequent calls to this method will consult the cache and return the previously compiled class if cached.

Specified by:

compile in interface IJavaParser

compile

public ClassJavaFileObject compile(JavaFileObject jfo,
                                   String fqn,
                                   Iterable<String> options,
                                   DiagnosticCollector<JavaFileObject> errorHandler)

Compiles fresh, no caching. Intended for use with parser feedback tooling e.g., a Java editor.
