Validation Rules

Rule Type Applicability The qualified name of this element must be correct. Error In DDMS 2.0 3.0 3.1 4.0.1/4.1 5.0 Each coordinate must be a valid Double. Error In DDMS 2.0 3.0 3.1 4.0.1/4.1 5.0 The position must be represented by 2 or 3 coordinates (to comply with WGS84E_2D or WGS84E_3D). Error In DDMS 2.0 3.0 3.1 4.0.1/4.1 5.0 The first coordinate must be a valid latitude. Error In DDMS 2.0 3.0 3.1 4.0.1/4.1 5.0 The second coordinate must be a valid longitude. Error In DDMS 2.0 3.0 3.1 4.0.1/4.1 5.0 Warnings from any SRS attributes are claimed by this component. Warning In DDMS 2.0 3.0 3.1 4.0.1/4.1 5.0 Does not perform any special validation on the third coordinate (height above ellipsoid).

Constructor Detail

Position

public Position(nu.xom.Element element)
         throws InvalidDDMSException

Constructor for creating a component from a XOM Element

Parameters:

element - the XOM element representing this

Throws:

InvalidDDMSException - if any required information is missing or malformed

Position

public Position(List<Double> coordinates,
                SRSAttributes srsAttributes)
         throws InvalidDDMSException

Constructor for creating a component from raw data

Parameters:

coordinates - a list of either 2 or 3 coordinate Double values

srsAttributes - the attribute group containing srsName, srsDimension, axisLabels, and uomLabels

Throws:

InvalidDDMSException - if any required information is missing or malformed

Method Detail

validate

protected void validate()
                 throws InvalidDDMSException

Description copied from class: AbstractBaseComponent

Base case for validation. This method can be overridden for more in-depth validation. It is always assumed that the subcomponents of a component are already valid.

Overrides:

validate in class AbstractBaseComponent

Throws:

InvalidDDMSException

See Also:

AbstractBaseComponent.validate()

validateWarnings

protected void validateWarnings()

Description copied from class: AbstractBaseComponent

Base case for warnings. This method can be overridden for more in-depth validation. It is always assumed that the subcomponents of a component are already valid.

Overrides:

validateWarnings in class AbstractBaseComponent

See Also:

AbstractBaseComponent.validateWarnings()

getJSONObject

public com.google.gson.JsonObject getJSONObject()

Description copied from class: AbstractBaseComponent

Renders this component as a JSON object, which can either be converted to a JSON string or inserted into the parent JSON object. Although this method is marked a public, it is only intended to be used internally, and is not part of the IDDMSComponent interface. Use the toJSON() method as the public way to get JSON output.

Specified by:

getJSONObject in class AbstractBaseComponent

See Also:

AbstractBaseComponent.getJSONObject()

getHTMLTextOutput

public String getHTMLTextOutput(OutputFormat format,
                                String prefix,
                                String suffix)

Description copied from class: AbstractBaseComponent

Renders this component as HTML or Text, with an optional prefix to nest it.

I consider this to be an internal method, that unfortunately must be marked as public to allow cross-package access when generating output. Use toHTML() and toText() as the formal, public methods to generate output.

Specified by:

getHTMLTextOutput in class AbstractBaseComponent

Parameters:

format - the desired format of this output

prefix - an optional prefix to put on each name.

suffix - an optional suffix to append to each name, such as an index.

Returns:

the representation of this component in the specified format

See Also:

AbstractBaseComponent.getHTMLTextOutput(OutputFormat, String, String)

equals

public boolean equals(Object obj)

Description copied from class: AbstractBaseComponent

Test for logical equality.

The base case tests against the name value and namespaceURI, as well as any child components classified as "nested components" and any security attributes. Extending classes may require additional rules for equality. This case automatically includes any nested components or security attributes.

Overrides:

equals in class AbstractBaseComponent

See Also:

Object.equals(Object)

hashCode

public int hashCode()

Description copied from class: AbstractBaseComponent

Returns a hashcode for the component.

This automatically includes any nested components or security attributes.

Overrides:

hashCode in class AbstractBaseComponent

See Also:

Object.hashCode()

getName

public static String getName(DDMSVersion version)

Accessor for the element name of this component, based on the version of DDMS used

Parameters:

version - the DDMSVersion

Returns:

an element name

getSRSAttributes

public SRSAttributes getSRSAttributes()

Accessor for the SRS Attributes. Will always be non-null, even if the attributes inside are not set.

getCoordinates

public List<Double> getCoordinates()

Accessor for the coordinates of the position. May return null, but cannot happen after instantiation.

getCoordinatesAsXsList

public String getCoordinatesAsXsList()

Accessor for the String representation of the coordinates
