All Implemented Interfaces:

JAnnotatedElement

public final class JAnnotationType
extends JStructure

Describes the definition of a annotation type class.

  JAnnotationType type = new JAnnotationType("RequestForEnhancement");
  type.addElement(new JAnnotationTypeElement("id", JType.Int));
  type.addElement(new JAnnotationTypeElement("synopsis", new JType("String")));
  JAnnotationTypeElement engineer;
  engineer = new JAnnotationTypeElement("engineer", new JType("String"));
  engineer.setDefaultString("\"[unassigned]\"");
  type.addElement(engineer);
  JAnnotationTypeElement date;
  date = new JAnnotationTypeElement("date", new JType("String"));
  date.setDefaultString("\"[unimplemented]\"");
  type.addElement(date);

outputs

  public @interface RequestForEnhancement {
      int id();
      String synopsis();
      String engineer() default "[unassigned]";
      String date() default "[unimplemented]";
  }

Constructor Details

JAnnotationType

public JAnnotationType(String name)

Creates a JAnnotationType of the given name.

Parameters:

name - Annotation name.

Method Details

addImport

public void addImport(String className)

Adds the given import to this JStructure. Note: You cannot import from the "default package," so imports with no package are ignored.

Specified by:

addImport in class JStructure

Parameters:

className - Name of the class to import.

addMember

public void addMember(JMember jMember)

Adds the given JMember to this JAnnotationType.

Specified by:

addMember in class JStructure

Parameters:

jMember - The JMember to add.

getElements

public JAnnotationTypeElement[] getElements()

Returns an Array containing all our JAnnotationTypeElements.

Returns:

An Array containing all our JAnnotationTypeElements.

getElement

public JAnnotationTypeElement getElement(String name)

Returns the member with the given name, or null if no member was found with the given name.

Parameters:

name - The name of the member to return.

Returns:

The member with the given name, or null if no member was found with the given name.

addElement

public void addElement(JAnnotationTypeElement jElement)

Adds the given JAnnotationTypeElement to this JAnnotationType.

Parameters:

jElement - The element to add.

getFields

public JField[] getFields()

Not implemented. Always throws a RuntimeException.
Returns an array of all the JFields of this JStructure.

Specified by:

getFields in class JStructure

Returns:

An array of all the JFields of this JStructure.

getField

public JField getField(String name)

Not implemented. Always throws a RuntimeException.
Returns the field with the given name, or null if no field was found with that name.

Specified by:

getField in class JStructure

Parameters:

name - The name of the field to return.

Returns:

The field with the given name, or null if no field was found with the given name.

addField

public void addField(JField jField)

Not implemented. Always throws a RuntimeException.
Adds the given JField to this JStructure.
This method is implemented by subclasses and should only accept the proper fields for the subclass otherwise an IllegalArgumentException will be thrown. For example a JInterface will only accept static fields.

Specified by:

addField in class JStructure

Parameters:

jField - The JField to add.

print

public void print(JSourceWriter jsw)

Deprecated.

Please use the Velocity-template based approach instead.

Prints the source code for this JStructure to the given JSourceWriter.

Specified by:

print in class JStructure

Parameters:

jsw - The JSourceWriter to print to.
