Method Details

getUrl

public String getUrl()

Returns the URL for this extension.

Note that before HAPI 0.9 this method returned a StringDt but as of HAPI 0.9 this method returns a plain string. This was changed because it does not make sense to use a StringDt here since the URL itself can not contain extensions and it was therefore misleading.

Specified by:

getUrl in interface IBaseExtension<ExtensionDt,IDatatype>

getUrlAsString

public String getUrlAsString()

Retained for backward compatibility

See Also:

• getUrl()

getValue

public IBaseDatatype getValue()

Returns the value of this extension, if one exists.

Note that if this extension contains extensions (instead of a datatype) then this method will return null. In that case, you must use BaseElement.getUndeclaredExtensions() and BaseElement.getUndeclaredModifierExtensions() to retrieve the child extensions.

Specified by:

getValue in interface IBaseExtension<ExtensionDt,IDatatype>

getValueAsPrimitive

public IPrimitiveDatatype<?> getValueAsPrimitive()

Returns the value of this extension, casted to a primitive datatype. This is a convenience method which should only be called if you are sure that the value for this particular extension will be a primitive.

Note that if this extension contains extensions (instead of a datatype) then this method will return null. In that case, you must use BaseElement.getUndeclaredExtensions() and BaseElement.getUndeclaredModifierExtensions() to retrieve the child extensions.

Throws:

ClassCastException - If the value of this extension is not a primitive datatype

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface IBase

isModifier

public boolean isModifier()

setModifier

public void setModifier(boolean theModifier)

setUrl

public ExtensionDt setUrl(String theUrl)

Specified by:

setUrl in interface IBaseExtension<ExtensionDt,IDatatype>

setUrl

public ExtensionDt setUrl(StringDt theUrl)

setValue

public ExtensionDt setValue(IBaseDatatype theValue)

Specified by:

setValue in interface IBaseExtension<ExtensionDt,IDatatype>

getAllPopulatedChildElementsOfType

@Deprecated
public <T extends IElement> List<T> getAllPopulatedChildElementsOfType(Class<T> theType)

Deprecated.

Description copied from interface: ICompositeElement

Returns a list containing all child elements matching a given type

Specified by:

getAllPopulatedChildElementsOfType in interface ICompositeElement

Parameters:

theType - The type to match. If set to null, all child elements will be returned

getExtension

public List<ExtensionDt> getExtension()

Specified by:

getExtension in interface IBaseExtension<ExtensionDt,IDatatype>

toString

public String toString()

Overrides:

toString in class Object
