  • Method Details

    • newInstance

      IJavaObject newInstance(String signature, IJavaValue[] args, IJavaThread thread) throws org.eclipse.debug.core.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:
      org.eclipse.debug.core.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 org.eclipse.debug.core.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:
      org.eclipse.debug.core.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 org.eclipse.debug.core.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:
      org.eclipse.debug.core.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 org.eclipse.debug.core.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:
      org.eclipse.debug.core.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 org.eclipse.debug.core.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:
      org.eclipse.debug.core.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 org.eclipse.debug.core.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:
      org.eclipse.debug.core.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:
