Method Detail

parseCompilationUnit

public static com.github.javaparser.ast.CompilationUnit parseCompilationUnit(InputStream inputStream)

Parses the Java code contained in the InputStream and returns a CompilationUnit that represents it.

This is like StaticJavaParser.parse, but it does not lead to memory leaks because it creates a new instance of JavaParser each time it is invoked. Re-using StaticJavaParser causes memory problems because it retains too much memory.

Parameters:

inputStream - the Java source code

Returns:

CompilationUnit representing the Java source code

Throws:

com.github.javaparser.ParseProblemException - if the source code has parser errors

parseCompilationUnit

public static com.github.javaparser.ast.CompilationUnit parseCompilationUnit(File file)
                                                                      throws FileNotFoundException

Parses the Java code contained in the File and returns a CompilationUnit that represents it.

This is like StaticJavaParser.parse, but it does not lead to memory leaks because it creates a new instance of JavaParser each time it is invoked. Re-using StaticJavaParser causes memory problems because it retains too much memory.

Parameters:

file - the Java source code

Returns:

CompilationUnit representing the Java source code

Throws:

com.github.javaparser.ParseProblemException - if the source code has parser errors

FileNotFoundException - if the file was not found

parseCompilationUnit

public static com.github.javaparser.ast.CompilationUnit parseCompilationUnit(String javaSource)

Parses the Java code contained in the String and returns a CompilationUnit that represents it.

This is like StaticJavaParser.parse, but it does not lead to memory leaks because it creates a new instance of JavaParser each time it is invoked. Re-using StaticJavaParser causes memory problems because it retains too much memory.

Parameters:

javaSource - the Java source code

Returns:

CompilationUnit representing the Java source code

Throws:

com.github.javaparser.ParseProblemException - if the source code has parser errors

parseStubUnit

public static com.github.javaparser.ast.StubUnit parseStubUnit(InputStream inputStream)

Parses the stub file contained in the InputStream and returns a StubUnit that represents it.

This is like StaticJavaParser.parse, but it does not lead to memory leaks because it creates a new instance of JavaParser each time it is invoked. Re-using StaticJavaParser causes memory problems because it retains too much memory.

Parameters:

inputStream - the stub file

Returns:

StubUnit representing the stub file

Throws:

com.github.javaparser.ParseProblemException - if the source code has parser errors
