Field Detail

MAGIC_NUMBER

public static final long MAGIC_NUMBER

A pattern used to identify the "NAP" block record is in NAP format. This is a 28-bit unsigned integer field.

Constant Field Values

FULL_MAGIC_NUMBER

public static final long FULL_MAGIC_NUMBER

The pattern used to identify by the first 4 octets of the block header. This value contains the Record Type field + the Magic Number field for a convenient 32-bit value.

See Also:

Constant Field Values

MAGIC_PATTERN

public static final byte[] MAGIC_PATTERN

A byte pattern used to identify the "NAP" block record as NAP format. This is a 28-bit masked byte array.

FULL_MAGIC_PATTERN

public static final byte[] FULL_MAGIC_PATTERN

The pattern used to identify by the first 4 octets of the block header. This value contains the Record Type field + the Magic Number field for a convenient 4 byte pattern array. Full 32-bit mask.

BLOCKING_FACTOR

public static final long BLOCKING_FACTOR

Default blocking factor for BlockRecords

See Also:

Constant Field Values

PADDING_BOUNDARY

public static final int PADDING_BOUNDARY

Default padding boundary. That is all records of all types must be padded upto 64-bit or 8 byte boundary

See Also:

Constant Field Values

MANDATORY_ENCODING

public static final java.nio.ByteOrder MANDATORY_ENCODING

Mandatory byte encoding for all record headers and meta record contents. PacketRecord and Vendor record contents may contain data that is native to the OS it was stored in, and is outside of the NAP specification.
