Method Detail

recalculateChildren

protected void recalculateChildren()

Specified by:

recalculateChildren in class AbstractPropositionDefinition

isConcatenable

public boolean isConcatenable()

Description copied from interface: PropositionDefinition

Returns whether instances of this proposition definition are concatenable. A proposition is concatenable if, whenever it holds over two consecutive time intervals, it holds also over their union.

Specified by:

isConcatenable in interface PropositionDefinition

Returns:

true if concatenable, false if not.

isSolid

public boolean isSolid()

Description copied from interface: PropositionDefinition

Returns whether intervals of this type are solid, i.e., never hold over properly overlapping intervals. For example, a proposition representing a pregnancy is solid because it is not possible for two pregnancies to overlap in time. This field could be used for data and interval validation. It alternatively could be used to merge overlapping propositions if there are multiple ways to infer a proposition. This field is settable for some types of propositions.

Specified by:

isSolid in interface PropositionDefinition

Returns:

true if solid, false if not.

accept

public void accept(PropositionDefinitionVisitor propositionVisitor)

Description copied from interface: PropositionDefinitionVisitable

Performs some processing on a proposition definition.

Specified by:

accept in interface PropositionDefinitionVisitable

acceptChecked

public void acceptChecked(PropositionDefinitionCheckedVisitor propositionVisitor)
                   throws ProtempaException

Description copied from interface: PropositionDefinitionCheckedVisitable

Performs some processing on this proposition definition.

Specified by:

acceptChecked in interface PropositionDefinitionCheckedVisitable

Throws:

ProtempaException

setInducedBy

public void setInducedBy(TemporalExtendedPropositionDefinition[] inducedBy)

getInducedBy

public TemporalExtendedPropositionDefinition[] getInducedBy()

Returns the id of the proposition definition that induces this context.

Returns:

a proposition id String.

getOffset

public ContextOffset getOffset()

Returns the start and finish of an interval of this context relative to its inducing interval.

Returns:

a temporal ContextOffset.

setOffset

public void setOffset(ContextOffset offset)

Sets the start and finish of an interval of this context relative to its inducing interval.

Parameters:

offset - a temporal ContextOffset.

getSubContexts

public String[] getSubContexts()

Returns the ids of other context definitions that, together with this one, have a specific meaning when their intervals intersect.

Returns:

an array of context proposition ids.

setSubContexts

public void setSubContexts(String[] subContextOf)

Sets the ids of other context definitions that, together with this one, have a specific meaning when their intervals intersect.

Parameters:

subContextOf - an array of context proposition ids.

getGapFunction

public GapFunction getGapFunction()

setGapFunction

public void setGapFunction(GapFunction gapFunction)
