Method Detail

getType

public String getType()

Description copied from interface: Relation

Get the type of the relation (e.g. Relation.COREF).

Specified by:

getType in interface Relation

Returns:

the relation type.

getMembers

public int[] getMembers()

Description copied from interface: Relation

Gets the members of the relation.

Specified by:

getMembers in interface Relation

Returns:

an array containing annotation IDs.

toString

public String toString()

Overrides:

toString in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

getId

public Integer getId()

Description copied from interface: IdBearer

The ID.

Specified by:

getId in interface IdBearer

getFeatures

public FeatureMap getFeatures()

Description copied from interface: FeatureBearer

Get the feature set. This must follow the Java convention of returning a reference to the stored FeatureMap and not a copy. This means changes to the returned FeatureMap will be visible to any future callers of this method. It also means that there is no need to call setFeatures having updated the FeatureMap.

Specified by:

getFeatures in interface FeatureBearer

setFeatures

public void setFeatures(FeatureMap features)

Description copied from interface: FeatureBearer

Set the feature set

Specified by:

setFeatures in interface FeatureBearer

getUserData

public Object getUserData()

Description copied from interface: Relation

Gets the arbitrary data associated with this relation

Specified by:

getUserData in interface Relation

Returns:

the arbitrary data associated with this relation

setUserData

public void setUserData(Object data)

Description copied from interface: Relation

Sets the arbitrary data associated with this relation

Specified by:

setUserData in interface Relation

Parameters:

data - the arbitrary data associated with this relation
