Method Detail

recordUnpack

public SqlJetUnpackedRecord recordUnpack(int nKey,
                                         ISqlJetMemoryPointer pKey)

Description copied from interface: ISqlJetKeyInfo

Given the nKey-byte encoding of a record in pKey[], parse the record into a UnpackedRecord structure. Return a pointer to that structure. The calling function might provide szSpace bytes of memory space at pSpace. This space can be used to hold the returned VDbeParsedRecord structure if it is large enough. If it is not big enough, space is obtained from sqlite3_malloc(). The returned structure should be closed by a call to sqlite3VdbeDeleteUnpackedRecord().

Specified by:

recordUnpack in interface ISqlJetKeyInfo

Parameters:

nKey - Size of the binary record

pKey - The binary record

Returns:

getNField

public int getNField()

Returns:

the nField

setNField

public void setNField(int field)

Parameters:

field - the nField to set

getEnc

public SqlJetEncoding getEnc()

Returns:

the enc

setEnc

public void setEnc(SqlJetEncoding enc)

Parameters:

enc - the enc to set
