Interface JavaClassWriter

All Known Implementing Classes:

IOJavaClassWriter

public interface JavaClassWriter

This interface can be used to describe a java class -- either top level or inner. The resulting class definition can be viewed by calling Object.toString(), but the entire source definition is only available when used with a JavaFileWriter.

The order of the generated code is up to the implementation. For example, one implementation may accept fields and methods in any order and generate all fields together and all methods together, but maintain the order within the list of fields and methods. Another implementation may take the same input and generate fields and methods interspersed among each other in exactly the order they were added. Still another implementation may make no guarantee as to the order of members at all.

Method Detail

setClassDeclaration

void setClassDeclaration(int modifiers,
                         String className,
                         String[] comments)
                  throws IOException

Sets the information for the class declaration including modifiers, name, and comments. Note that the name must not be fully qualified.

Parameters:

modifiers - The modifier flags for this class.

className - The (non-qualified) name of this class.

comments - The comments shown just above the class declaration. The comments are passed as an array so the line separators can be added by the implementation. Note that not all implementations will choose to make use of this comment.

Throws:

IOException - If the class declaration information cannot be set.

setSuperclass

void setSuperclass(String name)
            throws IOException

Sets the superclass of this class. Note that the name format must be package style (that is - it can contain . but not / or $).

Parameters:

name - The name of the superclass.

Throws:

IOException - If the superclass cannot be set.

addInterface

void addInterface(String name)
           throws IOException

Adds an interface to the list of those implemented by this class.

Parameters:

name - The name of the interface.

Throws:

IOException - If the interface cannot be added.

addField

void addField(String name,
              int modifiers,
              String type,
              String initialValue,
              String[] comments)
       throws IOException

Adds a field to the list of those declared by this class. Note that the type format must be package style (that is - it can contain . but not / or $).

Parameters:

name - The name of the field.

modifiers - The modifier flags for this field.

type - A string representing the type of this field.

initialValue - A string representing the initial value of this field.

comments - The comments shown just above the declaration of this field. The comments are passed as an array so the line separators can be added by the implementation. Note that not all implementations will choose to make use of this comment.

Throws:

IOException - If the field information cannot be added.

addInitializer

void addInitializer(boolean isStatic,
                    String[] body,
                    String[] comments)
             throws IOException

Adds an initializer to this class.

Parameters:

isStatic - True if this is a static initializer, false otherwise.

body - The implementation block of the initializer. The body of the implementation is passed as an array so the line separators can be added by the implementation.

comments - The comments shown just above the initializer block. The comments are passed as an array so the line separators can be added by the implementation. Note that not all implementations will choose to make use of this comment.

Throws:

IOException - If the initializer information cannot be added.

addConstructor

void addConstructor(String name,
                    int modifiers,
                    String[] parameterNames,
                    String[] parameterTypes,
                    String[] exceptions,
                    String[] body,
                    String[] comments)
             throws IOException

Adds a constructor to this class. Note that the type format in the parameter type strings must be package style (that is - it can contain . but not / or $).

Parameters:

name - The name of the constructor - should be the same as the name of the class.

modifiers - The modifier flags for this constructor.

parameterNames - A list of parameter names.

parameterTypes - A list of parameter types.

exceptions - A list of exceptions.

body - The implementation block of the constructor. The body of the implementation is passed as an array so the line separators can be added by the implementation.

comments - The comments shown just above the constructor. The comments are passed as an array so the line separators can be added by the implementation. Note that not all implementations will choose to make use of this comment.

Throws:

IOException - If the constructor information cannot be added.

               String[] parameterTypes,
               String[] exceptions,
               String[] body,
               String[] comments)
        throws IOException

returnType - A string representing the return type of this method.

parameterNames - A list of parameter names.

parameterTypes - A list of parameter types.

exceptions - A list of exceptions.

body - The implementation block of the method. The body of the implementation is passed as an array so the line separators can be added by the implementation.

comments - The comments shown just above the method. The comments are passed as an array so the line separators can be added by the implementation. Note that not all implementations will choose to make use of this comment.

Throws:

IOException - If the method information cannot be added.
