LogLSN

• java.lang.Object

Fields Summary
static final LogLSN	HEAD_LSN Constants for particular LSN values.
static final LogLSN	TAIL_LSN
static final LogLSN	NULL_LSN
static final LogLSN	FIRST_LSN
static final int	SIZEOF This constant holds the size of the LogRecordEnding object.
int	offset Internal instance members.
int	extent

Constructors Summary
LogLSN() Default LogLSN constructor param return see offset = 0; extent = 0;
LogLSN(int ext, int off) LogLSN constructor param ext Extent for new LSN. param off Offset for new LSN. return see offset = off; extent = ext;
LogLSN(LogLSN lsn) LogLSN constructor param lsn Other LSN to be copied. return see offset = lsn.offset; extent = lsn.extent;
LogLSN(byte[] bytes, int index) Constructs a LogLSN from the given byte array. param bytes The array of bytes from which the LogLSN is to be constructed. param index The index in the array where copy is to start. return see offset = (bytes[index++]&255) + ((bytes[index++]&255) << 8) + ((bytes[index++]&255) << 16) + ((bytes[index++]&255) << 24); extent = (bytes[index++]&255) + ((bytes[index++]&255) << 8) + ((bytes[index++]&255) << 16) + ((bytes[index++]&255) << 24);

Methods Summary
final void	copy(com.sun.jts.CosTransactions.LogLSN other) makes the target LSN a copy of the parameter. param LogLSN The LSN to be copied. return see extent = other.extent; offset = other.offset;
final boolean	equals(com.sun.jts.CosTransactions.LogLSN other) Determines whether the given LSN is equal to the target. param other The other LogLSN to be compared. return see return offset == other.offset && extent == other.extent;
final boolean	greaterThan(com.sun.jts.CosTransactions.LogLSN other) Determines whether the target LSN is greater than the parameter. param other The other LogLSN to be compared. return see return ( (offset > other.offset && extent == other.extent) || extent > other.extent);
final boolean	isNULL() Determines whether the target LSN is NULL. param return see return offset == 0 && extent == 0;
final boolean	lessThan(com.sun.jts.CosTransactions.LogLSN other) Determines whether the target LSN is less than the parameter. param other The other LogLSN to be compared. return see return ( (offset < other.offset && extent == other.extent) || extent < other.extent);
final int	toBytes(byte[] bytes, int index) Makes a byte representation of the LogLSN. param bytes The array of bytes into which the LogLSN is to be copied. param index The index in the array where copy is to start. return Number of bytes copied. see bytes[index++] = (byte) offset; bytes[index++] = (byte)(offset >> 8); bytes[index++] = (byte)(offset >> 16); bytes[index++] = (byte)(offset >> 24); bytes[index++] = (byte) extent; bytes[index++] = (byte)(extent >> 8); bytes[index++] = (byte)(extent >> 16); bytes[index++] = (byte)(extent >> 24); return SIZEOF;
public final java.lang.String	toString() This method is called to direct the object to format its state to a String. param return The formatted representation of the object. see return "LSN(ext="/*#Frozen*/+extent+",off="/*#Frozen*/+offset+")"/*#Frozen*/;
