Method Detail

initialize

public void initialize(org.apache.uima.UimaContext context)
                throws org.apache.uima.resource.ResourceInitializationException

Specified by:

initialize in interface org.apache.uima.analysis_component.AnalysisComponent

Specified by:

initialize in interface org.uimafit.factory.initializable.Initializable

Overrides:

initialize in class EventAttributeAnnotator<String>

Throws:

org.apache.uima.resource.ResourceInitializationException

getDefaultValue

protected String getDefaultValue()

Description copied from class: EventAttributeAnnotator

The attribute value that should be considered as a default, e.g. "NONE". When the attribute value is null in the CAS, this value will be used instead. Additionally, when the classifier produces this value, no attribute will be added.

Specified by:

getDefaultValue in class EventAttributeAnnotator<String>

Returns:

The default attribute value.

getAttribute

protected String getAttribute(org.cleartk.timeml.type.Event event)

Description copied from class: EventAttributeAnnotator

Get the attribute value from the Event annotation. Typically this will be by calling something like Event.getTense(). If this method returns null, EventAttributeAnnotator.getDefaultValue() will be called to produce an appropriate attribute value.

Specified by:

getAttribute in class EventAttributeAnnotator<String>

Parameters:

event - The Event annotation whose attribute is to be retrieved.

Returns:

The selected attribute value.

setAttribute

protected void setAttribute(org.cleartk.timeml.type.Event event,
                            String value)

Description copied from class: EventAttributeAnnotator

Set the attribute value on the Event annotation. Typically this will be by calling something like Event.setTense(String). This method will not be called if the value is equal to EventAttributeAnnotator.getDefaultValue().

Specified by:

setAttribute in class EventAttributeAnnotator<String>

Parameters:

event - The Event annotation whose attribute is to be set.

value - The new attribute value.
