        Data getComponentAt​(int offset)
        Deprecated, for removal: This API element is subject to removal in a future version.
        method name has been changed to better reflect behavior. The method getComponentContaining(int) should be used instead.
        Return the first immediate child component that contains the byte at the given offset. It is important to note that with certain datatypes there may be more than one component containing the specified offset (see getComponentsContaining(int)).
        Parameters:
        offset - the amount to add to this data items address to get the address of the requested data item.
        Returns:
        first data component containing offset or null
      • getComponentContaining

        Data getComponentContaining​(int offset)
        RReturn the first immediate child component that contains the byte at the given offset. It is important to note that with certain datatypes there may be more than one component containing the specified offset (see getComponentsContaining(int)).
        Parameters:
        offset - the amount to add to this data items address to get the
        Returns:
        first data component containing offset or null address of the requested data item.
      • getComponentsContaining

        java.util.List<Data> getComponentsContaining​(int offset)
        Returns a list of all the immediate child components that contain the byte at the given offset.

        For a union, this will return all the components (if the offset is 0). The presence of bit-fields or zero-length components may cause multiple components to be returned.

        Parameters:
        offset - the amount to add to this data items address to get the address of the requested data item.
        Returns:
        a list of all the immediate child components that contain the byte at the given offset or null if offset is out of bounds.

This method immediately goes to the lowest level data item. If the minimum offset of a component is specified, the only first component containing the offset will be considered (e.g., 0-element array).
        Parameters:
        offset - the offset
        Returns:
        primitive component containing this offset
