readExternal in class AbstractQueryIndex

Throws:

IOException

ClassNotFoundException

writeExternal

public void writeExternal(ObjectOutput out)
                   throws IOException

Specified by:

writeExternal in interface Externalizable

Overrides:

writeExternal in class AbstractQueryIndex

Throws:

IOException

supportsTemplateIndex

public boolean supportsTemplateIndex()

Description copied from interface: IQueryIndexScanner

Returns true if this index scanner supports template indexing

build
