public class ExtSSTRecord
extends Record

Title: Extended Static String Table

Description: This record is used for a quick lookup into the SST record. This record breaks the SST table into a set of buckets. The offsets to these buckets within the SST record are kept as well as the position relative to the start of the SST record.

ExtSSTRecord

public ExtSSTRecord()

ExtSSTRecord

public ExtSSTRecord(RecordInputStream in)

Constructs a EOFRecord record and sets its fields appropriately.

Parameters:

in - the RecordInputstream to read the record from

Method Detail

validateSid

protected void validateSid(short id)

Description copied from class: Record

called by constructor, should throw runtime exception in the event of a record passed with a differing ID.

Specified by:

validateSid in class Record

Parameters:

id - alleged id for this record

fillFields

protected void fillFields(RecordInputStream in)

Description copied from class: Record

called by the constructor, should set class level fields. Should throw runtime exception for bad/icomplete data.

Specified by:

fillFields in class Record

Parameters:

in - the RecordInputstream to read the record from

setNumStringsPerBucket

public void setNumStringsPerBucket(short numStrings)

getNumInfoRecords

public int getNumInfoRecords()

getInfoRecordAt

public ExtSSTInfoSubRecord getInfoRecordAt(int elem)

toString

public java.lang.String toString()

Description copied from class: Record

get a string representation of the record (for biffview/debugging)

Overrides:

toString in class Record

serialize

public int serialize(int offset,
                     byte[] data)

Description copied from class: Record

offset - to begin writing at

data - byte array containing instance data

Returns:

number of bytes written

getRecordSize

public int getRecordSize()

getRecordSize in class Record

getNumberOfInfoRecsForStrings

public static final int getNumberOfInfoRecsForStrings(int numStrings)

getRecordSizeForStrings

public static final int getRecordSizeForStrings(int numStrings)

Given a number of strings (in the sst), returns the size of the extsst record

getSid

public short getSid()

Description copied from class: Record

return the non static version of the id for this record.

Specified by:

getSid in class Record

setBucketOffsets

public void setBucketOffsets(int[] bucketAbsoluteOffsets,
                             int[] bucketRelativeOffsets)
