@UML(identifier="MD_SampleDimension", specification=ISO_19115) public class DefaultSampleDimension extends DefaultRangeDimension
The characteristic of each dimension (layer) included in the resource. The following property is conditional (i.e. mandatory under some circumstances) in a well-formed metadata according ISO 19115:
MD_Sample­Dimension   └─units……………………… Units of data in each dimension included in the resource.
Note on International Standard versions
This class is derived from a new type defined in the ISO 19115 international standard published in 2014, while GeoAPI 3.0 is based on the version published in 2003. Consequently this implementation class does not yet implement a GeoAPI interface, but is expected to do so after the next GeoAPI releases. When the interface will become available, all references to this implementation class in Apache SIS will be replaced be references to the Sample­Dimension interface.

Terminology

Data values should be physical values expressed in the unit of measurement given by get­Units(). Cell values are values stored in the device, before conversion to data values by application of scale factor and offset.

Limitations

  • Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
  • Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use XML instead.

  • Constructor Details

    • DefaultSampleDimension

      public DefaultSampleDimension()
      Constructs an initially empty sample dimension.

    • DefaultSampleDimension

      public DefaultSampleDimension(DefaultSampleDimension object)
      Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, because the other metadata contained in the given object are not recursively copied.

      Note on properties validation

      This constructor does not verify the property values of the given metadata (e.g. whether it contains unexpected negative values). This is because invalid metadata exist in practice, and verifying their validity in this copy constructor is often too late. Note that this is not the only hole, as invalid metadata instances can also be obtained by unmarshalling an invalid XML document.
      Parameters:
      object - the metadata to copy values from, or null if none.
