Method Detail

allocate

public void allocate(int size)

Description copied from interface: ISqlJetMemoryBuffer

Allocate chunk of memory. If memory already has allocated then fries current chunk and allocates new.

Specified by:

allocate in interface ISqlJetMemoryBuffer

Overrides:

allocate in class SqlJetByteBuffer

Parameters:

size - size of chunk in bytes

asArray

public byte[] asArray()

Specified by:

asArray in interface ISqlJetMemoryBuffer

Overrides:

asArray in class SqlJetByteBuffer

Returns:

fill

public void fill(int from,
                 int count,
                 byte value)

Specified by:

fill in interface ISqlJetMemoryBuffer

Overrides:

fill in class SqlJetByteBuffer

getBytes

public void getBytes(int pointer,
                     byte[] bytes,
                     int to,
                     int count)

Specified by:

getBytes in interface ISqlJetMemoryBuffer

Overrides:

getBytes in class SqlJetByteBuffer

putBytes

public void putBytes(int pointer,
                     byte[] bytes,
                     int from,
                     int count)

Specified by:

putBytes in interface ISqlJetMemoryBuffer

Overrides:
