Constructor Detail

JCJavaClass

public JCJavaClass(JCJavaRuntime javaRuntime,
                   String className)
            throws JCInvalidArgumentsException

Parameters:

javaRuntime -

className -

Throws:

JCInvalidArgumentsException

Method Detail

getComponentType

public JavaClass getComponentType()
                           throws CorruptDataException

component type only for arrays

Specified by:

getComponentType in interface JavaClass

Returns:

a JavaClass representing the component type of this array class

Throws:

CorruptDataException

getModifiers

public int getModifiers()
                 throws CorruptDataException

Description copied from interface: JavaClass

Return the Java language modifiers for this class.

The modifiers are defined by the JVM Specification.

Return MODIFIERS_UNAVAILABLE if the modifiers are unavailable. This might be the case if DTFJ is operating against an artefact such as a portable heap dump that does not contain information about a class's modifiers.

Note that, for inner classes, the actual modifiers are returned, not the synthetic modifiers. For instance, a class will never have its 'protected' modifier set, even if the inner class was a protected member, since 'protected' is not a legal modifier for a class file.

Specified by:

getModifiers in interface JavaClass

Returns:

the modifiers for this class

Throws:

CorruptDataException - if modifiers not set

See Also:

JavaClass.getModifiers()

getName

public String getName()
               throws CorruptDataException

Description copied from interface: JavaClass

Get the name of the class.

Specified by:

getName in interface JavaClass

Returns:

the name of the class in the form: "full/package/class$innerclass"

Throws:

CorruptDataException - if class name is not set

See Also:

JavaClass.getName()

getObject

public JavaObject getObject()
                     throws CorruptDataException

Instance object of this class

Specified by:

getObject in interface JavaClass

Returns:

the java.lang.Class object associated with this class

Throws:

CorruptDataException - if no instance of this class is set

See Also:

JavaClass.getObject()

getSuperclass

public JavaClass getSuperclass()
                        throws CorruptDataException

Returning null is permissable for cases like Object, primitives, interfaces, etc..

Specified by:

getSuperclass in interface JavaClass

Returns:

JavaClass of this class's superclass.

Throws:

CorruptDataException - if super class not found.

See Also:

JavaClass.getSuperclass()

isArray

public boolean isArray()
                throws CorruptDataException

Same as the J9 System Core implementation for DTFJ.

Specified by:

isArray in interface JavaClass

Returns:

true if an array

Throws:

CorruptDataException
