Release 3.5

org.eclipse.jdt.debug.core
Interface IJavaClassType

All Superinterfaces:
IAdaptable, IDebugElement, IJavaReferenceType, IJavaType

public interface IJavaClassType
extends IJavaReferenceType

The class of an object on a Java debug target.

Since:
2.0

IJavaValue
Restriction:
This interface is not intended to be implemented by clients.
Restriction:
This interface is not intended to be extended by clients.

Method Detail

newInstance

IJavaObject newInstance(
String signature,
                        
IJavaValue[] args,
                        
IJavaThread thread)
                        throws 
DebugException
Returns a new instance of this class by invoking the constructor with the given signature and arguments in the specified thread. The given thread is resumed to perform this method invocation and suspends in its original location when this method invocation is complete. This method does not return until the method invocation is complete. Resuming the specified thread can result in breakpoints being hit, infinite loops, and deadlock.

Parameters:
signature - the JNI style signature of the method to be invoked
args - the arguments of the constructor, which can be null or empty if there are none
thread - the thread in which to invoke the constructor
Returns:
the result of invoking the constructor
Throws:
DebugException - if this method fails. Reasons include:
  • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
  • This type does not implement the specified constructor
  • An exception occurs while invoking the specified constructor
  • The given thread is already performing a message send, (status code IJavaThread.ERR_NESTED_METHOD_INVOCATION)
  • The given thread is not currently suspended (status code IJavaThread.ERR_THREAD_NOT_SUSPENDED)
  • The given thread was explicitly suspended (status code IJavaThread.ERR_INCOMPATIBLE_THREAD_STATE)

sendMessage

IJavaValue sendMessage(
String selector,
                       
String signature,
                       
IJavaValue[] args,
                       
IJavaThread thread)
                       throws 
DebugException
Returns the result of sending the specified message to this class with the given arguments in the specified thread (invokes a static method on this type). The given thread is resumed to perform this method invocation and suspends in its original location when this method invocation is complete. This method does not return until the method invocation is complete. Resuming the specified thread can result in breakpoints being hit, infinite loops, and deadlock.

Parameters:
selector - the selector of the method to be invoked
signature - the JNI style signature of the method to be invoked
args - the arguments of the method, which can be null or empty if there are none
thread - the thread in which to invoke the method
Returns:
the result of invoking the method
Throws:
DebugException - if this method fails. Reasons include:
  • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
  • This object does not implement the specified method
  • An exception occurs while invoking the specified method
  • The given thread is already performing a message send, (status code IJavaThread.ERR_NESTED_METHOD_INVOCATION)
  • The given thread is not currently suspended (status code IJavaThread.ERR_THREAD_NOT_SUSPENDED)
  • The given thread was explicitly suspended (status code IJavaThread.ERR_INCOMPATIBLE_THREAD_STATE)

getSuperclass

IJavaClassType getSuperclass()
                             throws 
DebugException
Returns the superclass of this class type, or null if no such class exists.

Returns:
the superclass of this class type, or null
Throws:
DebugException - if this method fails. Reasons include:
  • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.

getInterfaces

IJavaInterfaceType[] getInterfaces()
                                   throws 
DebugException
Returns the interface objects associated with the interfaces this class directly implements. Only those interfaces declared in the implements clause for this class are included.

Returns:
the interface objects associated with the interfaces this class directly implements
Throws:
DebugException - if this method fails. Reasons include:
  • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
Since:
3.0

getAllInterfaces

IJavaInterfaceType[] getAllInterfaces()
                                      throws 
DebugException
Returns the interface objects associated with all interfaces this class implements, directly or indirectly.

Returns:
the interface objects associated with the interfaces this class directly implements, directly or indirectly
Throws:
DebugException - if this method fails. Reasons include:
  • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
Since:
3.0

isEnum

boolean isEnum()
               throws 
DebugException
Returns whether this type is declared as a type safe enumeration.

Returns:
true if this type is a type safe enumeration, false otherwise.
Throws:
DebugException - if this method fails. Reasons include:
  • Failure communicating with the VM. The DebugException's status code contains the underlying exception responsible for the failure.
Since:
3.1
