Class JavaClass

java.lang.Object
  extended by org.apache.tomcat.util.bcel.classfile.AccessFlags
      extended by org.apache.tomcat.util.bcel.classfile.JavaClass
All Implemented Interfaces:
Serializable, Cloneable, Comparable<JavaClass>

public class JavaClass
extends AccessFlags
implements Cloneable, Comparable<JavaClass>

Represents a Java class, i.e., the data structures, constant pool, fields, methods and commands contained in a Java .class file. See JVM specification for details. The intent of this class is to represent a parsed or otherwise existing class file. Those interested in programatically generating classes should see the ClassGen class.

Constructor Detail

JavaClass

public JavaClass(int class_name_index,
                 int superclass_name_index,
                 String file_name,
                 int major,
                 int minor,
                 int access_flags,

                 int[] interfaces,
                 Field[] fields,
                 Method[] methods,
                 Attribute[] attributes)
Constructor gets all contents as arguments.

Parameters:
class_name_index - Index into constant pool referencing a ConstantClass that represents this class.
superclass_name_index - Index into constant pool referencing a ConstantClass that represents this class's superclass.
file_name - File name
major - Major compiler version
minor - Minor compiler version
access_flags - Access rights defined by bit flags
constant_pool - Array of constants
interfaces - Implemented interfaces
fields - Class fields
methods - Class methods
attributes - Class attributes
Method Detail

getAttributes

public Attribute[] getAttributes()
Returns:
Attributes of the class.

getAnnotationEntries

public AnnotationEntry[] getAnnotationEntries()

getClassName

public String getClassName()
Returns:
Class name.

getInterfaceNames

public String[] getInterfaceNames()
Returns:
Names of implemented interfaces.

getSuperclassName

public String getSuperclassName()
returns the super class name of this class. In the case that this class is java.lang.Object, it will return itself (java.lang.Object). This is probably incorrect but isn't fixed at this time to not break existing clients.

Returns:
Superclass name.

toString

public String toString()
Overrides:
toString in class Object
Returns:
String representing class contents.

isSuper

public final boolean isSuper()

equals

public boolean equals(Object obj)
Return value as defined by given BCELComparator strategy. By default two JavaClass objects are said to be equal when their class names are equal.

Overrides:
equals in class Object
See Also:
Object.equals(java.lang.Object)

compareTo

public int compareTo(JavaClass obj)
Return the natural ordering of two JavaClasses. This ordering is based on the class name

Specified by:
compareTo in interface Comparable<JavaClass>

hashCode

public int hashCode()
Return value as defined by given BCELComparator strategy. By default return the hashcode of the class name.

Overrides:
hashCode in class Object
See Also:
Object.hashCode()
