Package org.apache.sis.util.iso

Class DefaultRecord

java.lang.Object
org.apache.sis.util.iso.DefaultRecord
All Implemented Interfaces:
Serializable, org.opengis.util.Record
public class DefaultRecord extends Object implements org.opengis.util.Record, Serializable
A list of logically related elements as (name, value) pairs in a dictionary. By definition, all record fields have a [1 … 1] multiplicity (for a more flexible construct, see features). Since all fields are expected to be assigned a value, the initial values on DefaultRecord instantiation are unspecified. Some may be null, or some may be zero.

Limitations

  • Multi-threading: DefaultRecord instances are not thread-safe. Synchronization, if needed, shall be done externally by the caller.
  • Serialization: this class is serializable if the associated RecordType and all values are also serializable. Note in particular that DefaultRecordSchema is currently not serializable, so users wanting serialization may need to define their own schema implementation.

  • Constructor Details

    • DefaultRecord

      public DefaultRecord(org.opengis.util.RecordType type)
      Creates a new record for the given record type. The initial values are unspecified - they may be null or zero. Callers can assign values by a call to setAll(Object[]).
      Parameters:
      type - the type definition of the new record.

    • DefaultRecord

      public DefaultRecord(org.opengis.util.Record record)
      Creates a new record initialized to a shallow copy of the given record. The fields contained in the given record are not recursively copied.
      Parameters:
      record - the record to copy (cannot be null).

  • Method Details

    • castOrCopy

      public static DefaultRecord castOrCopy(org.opengis.util.Record other)
      Returns a SIS implementation with the name and fields of the given arbitrary implementation. This method performs the first applicable action in the following choices:
      • If the given object is null, then this method returns null.
      • Otherwise if the given object is already an instance of DefaultRecord, then it is returned unchanged.
      • Otherwise a new DefaultRecord instance is created using the copy constructor and returned. Note that this is a shallow copy operation, since the fields contained in the given object are not recursively copied.
      Parameters:
      other - The object to get as a SIS implementation, or null if none.
      Returns:
      A SIS implementation containing the fields of the given object (may be the given object itself), or null if the argument was null.
      Since:
      0.8

    • getRecordType

      public org.opengis.util.RecordType getRecordType()
      Returns the type definition of this record.
      Specified by:
      getRecordType in interface org.opengis.util.Record
      Returns:
      the type definition of this record.

    • getAttributes

      @Deprecated public Map<org.opengis.util.MemberName,Object> getAttributes()
      Deprecated.
      Renamed getFields() for consistency with the 2015 revision of ISO 19103 standard.
      Returns the dictionary of all (name, value) pairs in this record. This method returns a view which will delegate all get and put operations to the locate(MemberName) and set(MemberName, Object) methods respectively.
      Specified by:
      getAttributes in interface org.opengis.util.Record
      Returns:
      the dictionary of all (name, value) pairs in this record.
