Interface FsIndexDescription

All Superinterfaces:

Cloneable, MetaDataObject, Serializable, XMLizable

All Known Implementing Classes:

FsIndexDescription_impl

public interface FsIndexDescription
extends MetaDataObject

A description of a CAS feature structure index. This implements MetaDataObject, which implements XMLizable, so it can be serialized to and deserialized from an XML element.

Method Details

getLabel

String getLabel()

Gets the label of this index. This is the identifier used to retrieve the index from the CAS's Index Repository.

Returns:

the label of this index.

setLabel

void setLabel(String aLabel)

Sets the label of this index. This is the identifier used to retrieve the index from the CAS's Index Repository.

Parameters:

aLabel - the label of this index.

getTypeName

String getTypeName()

Gets the Type name for this index. This determines what type of FeatureStructures are contained in the index.

Returns:

the type name for this index

setTypeName

void setTypeName(String aTypeName)

Sets the Type name for this index. This determines what type of FeatureStructures are contained in the index.

Parameters:

aTypeName - the type name for this index

getKind

String getKind()

Gets the "kind" of index. There are currently three kinds of indexes - "sorted", "set", and "bag" (see FSIndex for definitions). If this is null, "sorted" is assumed as the default.

Returns:

the kind of index

setKind

void setKind(String aKind)

Sets the "kind" of index. There are currently three kinds of indexes - sorted, set, and bag (see FSIndex for definitions). If this is null, "sorted" is assumed as the default.

Parameters:

aKind - the kind of index

getKeys

FsIndexKeyDescription[] getKeys()

Gets the keys for this index. The keys determine the ordering of FeatureStructures in this index.

Returns:

the keys for this index

setKeys

void setKeys(FsIndexKeyDescription[] aKeys)

Sets the keys for this index. The keys determine the ordering of FeatureStructures in this index.

Parameters:

aKeys - the keys for this index
