  • Method Details

    • getSignature

      String getSignature() throws DebugException
      Returns the JNI-style signature for the declared type of this variable, or null if the type associated with the signature is not yet loaded in the target VM.
      Returns:
      signature, or null if not accessible
      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.
      • The type associated with the signature is not yet loaded

    • getGenericSignature

      String getGenericSignature() throws DebugException
      Returns the generic signature as defined in the JVM specification for the declared type of this variable, or null if the type associated with the signature is not yet loaded in the target VM. Returns the same value as #getSignature() if the declared type of this variable is not a generic type.
      Returns:
      generic signature, or null if not accessible
      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.
      • The type associated with the signature is not yet loaded
      Since:
      3.1

    • getJavaType

      IJavaType getJavaType() throws DebugException
      Returns the declared type of this variable.
      Returns:
      the declared type of this variable
      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.
      • The type associated with the signature is not yet loaded
      Since:
      2.0

    • isLocal

      boolean isLocal() throws DebugException
      Returns whether this variable is local.
      Returns:
      whether this variable is a local variable
      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.
