Defense StandardsInterface ILcdVPFFACCFeature

All Known Subinterfaces:

ILcdVPFFeature

public interface ILcdVPFFACCFeature

Represents a DIGEST FACC feature (typically is a real world object), having a feature code that describes the type of the feature, and an ordered set of attributes describing the properties of the feature.

FACC (Feature and Attribute Coding Catalogue) is a dictionary of features, attributes and attribute values organized in a standardized coding system. FACC is part of the DIGEST standard (Digital Geographic Information Exchange Standard). It is mainly used by the GeoSym symbology, which uses FACC to retrieve feature and attributes codes for an object to be visualized.

FACC attributes can be accessed sequentially, using an index, or using their three-character alphanumeric attribute code, as defined in the FACC specification. The Java class used to represent the attributes depends on the attribute definition, see TLcdVPFFeatureClass for an overview of how VPF types are mapped on Java classes.

Method Summary

Modifier and Type	Method and Description
String	getAttributeCode(int aIndex) Returns the FACC attribute code at the specified index.
int	getAttributeCount() Returns the number of FACC attributes available for this feature.
Object	getAttributeValue(int aIndex) Returns the DIGEST attribute value of the attribute at the given index.
Object	getAttributeValue(String aAttributeCode) Returns the DIGEST attribute value of the attribute with the specified code.
String	getFeatureCode() Returns the FACC feature code of this feature, defining the type of this object (for example, a road, a buoy, ...).

Method Detail

getFeatureCode

String getFeatureCode()

Returns the FACC feature code of this feature, defining the type of this object (for example, a road, a buoy, ...).

The feature code is a five-character code, starting with two letters indicating the category and subcategory, followed by a three-digit number indicating the type within the given subcategory.

Returns:

the FACC feature code of this feature.

getAttributeCount

int getAttributeCount()

Returns the number of FACC attributes available for this feature.

Returns:

the number of FACC attributes available for this feature.

getAttributeCode

String getAttributeCode(int aIndex)

Returns the FACC attribute code at the specified index.

The attribute code is a three-character alphanumeric code.

Parameters:

aIndex - the index of the attribute whose code is to be returned.

Returns:

the FACC attribute code of the attribute at the specified index.

Throws:

IndexOutOfBoundsException - if aIndex < 0 || aIndex >= getAttributeCount.

getAttributeValue

Object getAttributeValue(int aIndex)

Returns the DIGEST attribute value of the attribute at the given index. The Java class of the returned object depends on the attribute definition, see TLcdVPFFeatureClass for an overview of how VPF types are mapped on Java classes.

Parameters:

aIndex - the index of the attribute whose value is to be returned.

Returns:

the DIGEST attribute value of the attribute at the specified index.

Throws:

IndexOutOfBoundsException - if aIndex < 0 || aIndex >= getAttributeCount.

getAttributeValue

Object getAttributeValue(String aAttributeCode)

Returns the DIGEST attribute value of the attribute with the specified code. The Java class of the returned object depends on the attribute definition, see TLcdVPFFeatureClass for an overview of how VPF types are mapped on Java classes.

Parameters:

aAttributeCode - the attribute code of the attribute whose value is to be returned.

Returns:

the DIGEST attribute value of the attribute at the specified index, or null if no attribute is available with the given attribute code.
