Method Detail

parse

public static CompilationUnit parse(File file)
                             throws ParseException,
                                    IOException

Parses a Java source file and store the AST into a CompilationUnit object. The default encoding is UTF-8.

Parameters:

file - source code to parse

Returns:

the abstract syntax tree (AST)

Throws:

ParseException - when the code contains an invalid syntax

IOException - file can not be read.

parse

public static CompilationUnit parse(File file,
                    String encoding)
                             throws ParseException,
                                    IOException

Parses a Java source file with a given encoding and store the AST into a CompilationUnit object.

Parameters:

file - source code to parse

encoding -

Returns:

the abstract syntax tree (AST)

Throws:

ParseException - when the code contains an invalid syntax

IOException - file can not be read.

parse

public static CompilationUnit parse(Reader reader)
                             throws ParseException,
                                    IOException

Parses Java code and store the AST into a CompilationUnit object.

Parameters:

reader - to read the source code to parse

Returns:

the abstract syntax tree (AST)

Throws:

ParseException - when the code contains an invalid syntax

IOException - the code can not be read.

parse

public static CompilationUnit parse(String code)
                             throws ParseException

Parses Java code and store the AST into a CompilationUnit object. All nodes has their start and end location (line and column)

Parameters:

code - source code to parse.

Returns:

the abstract syntax tree (AST).

Throws:

ParseException - when the code contains an invalid syntax.

parse

public static CompilationUnit parse(String code,
                    boolean withoutLocation)
                             throws ParseException

Parses Java code and store the AST into a CompilationUnit object with or without the nodes start & end locations (line numbers and columns).

Parameters:

code - source code to parse.

withoutLocation - true does not fulfill the location information inside the AST. Otherwise, it is defined.

Returns:

the abstract syntax tree (AST).

Throws:

ParseException - when the code contains an invalid syntax.

parse

public static Node parse(Class<?> clazz,
         String text)
                  throws ParseException

Parses any fragment of code and store the result into the subclass of Node defined. For example, if you need to parse a single method, the class must be MethodDeclaration. The result does NOT contain the location of the AST nodes.

Parameters:

clazz - the subclass of Node. The result will be instance of that class.

text - the fragment of code to parse.

Returns:

the partial abstract syntax tree (AST) produced.

Throws:

ParseException - when the code contains an invalid syntax.

parse

public static Node parse(Class<?> clazz,
         String text,
         boolean withoutLocation)
                  throws ParseException

Parses any fragment of code and store the result into the subclass of Node defined. For example, if you need to parse a single method, the class must be MethodDeclaration. The result can contain or not the location of all AST nodes.

Parameters:

clazz - the subclass of Node. The result will be instance of that class.

text - the fragment of code to parse.

withoutLocation - true does not fulfill the location information inside the AST. Otherwise, it is defined.

Returns:

the partial abstract syntax tree (AST) produced.

Throws:

ParseException
