    • getSignature

      String getSignature() throws org.eclipse.debug.core.DebugException
      Returns the JNI-style signature for the type of this value, or null if the value is null.
      Returns:
      signature, or null if signature is 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.
      • The type associated with the signature is not yet loaded

    • getGenericSignature

      String getGenericSignature() throws org.eclipse.debug.core.DebugException
      Returns the generic signature as defined in the JVM specification for the type of this value. Returns null if the value is null, or if the type of this value is not a generic type.
      Returns:
      signature, or null if generic signature not available
      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.
      • The type associated with the signature is not yet loaded
      Since:
      3.1

    • getJavaType

      IJavaType getJavaType() throws org.eclipse.debug.core.DebugException
      Returns the type of this value, or null if this value represents the null value
      Returns:
      the type of this value, or null if this value represents the null value
      Throws:
      org.eclipse.debug.core.DebugException - if the request fails
      Since:
      2.0

    • isNull

      boolean isNull()
      Returns whether this value represents null.
      Returns:
      whether this value represents null
