Class JavaParser

java.lang.Object

manifold.internal.javac.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 Manifold types. This feature enables bi-directional Java interop with Manifold.

Constructor Details

JavaParser

public JavaParser(IManifoldHost host)

For internal use only. Usea IManifoldHost.getJavaParser()

Method Details

getHost

public IManifoldHost getHost()

parseType

public boolean parseType(String fqn,
 List<com.sun.source.tree.CompilationUnitTree> trees,
 DiagnosticCollector<JavaFileObject> errorHandler)

Specified by:

parseType in interface IJavaParser

parseText

public boolean parseText(String src,
 List<com.sun.source.tree.CompilationUnitTree> trees,
 Consumer<com.sun.source.util.SourcePositions> sourcePositions,
 Consumer<com.sun.source.util.DocTrees> docTrees,
 DiagnosticCollector<JavaFileObject> errorHandler)

Specified by:

parseText in interface IJavaParser

parseExpr

public com.sun.tools.javac.tree.JCTree.JCExpression parseExpr(String expr,
 DiagnosticCollector<JavaFileObject> errorHandler)

compile

public InMemoryClassJavaFileObject 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 InMemoryClassJavaFileObject 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.

Specified by:

compile in interface IJavaParser

compile

public Collection<InMemoryClassJavaFileObject> compile(Collection<JavaFileObject> files,
 Iterable<String> options,
 DiagnosticCollector<JavaFileObject> errorHandler)

Compiles a collection of java source files, intended for use a command line compiler.

Specified by:

compile in interface IJavaParser

findJavaSource

public manifold.rt.api.util.Pair<JavaFileObject, String> findJavaSource(String fqn,
 DiagnosticListener<JavaFileObject> errorHandler)

Specified by:

findJavaSource in interface IJavaParser

getJavacTask

public com.sun.tools.javac.api.BasicJavacTask getJavacTask()

clear

public void clear()

Specified by:

clear in interface IJavaParser
