Constructor Details

LogAppendResult

public LogAppendResult(LogStreamId stream,
 LogOffset firstOffset,
 LogOffset lastOffset,
 int recordCount,
 long bytesWritten,
 boolean fsynced)

Creates a validated append result.

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

Specified by:

toString in class Record

Returns:

a string representation of this object

hashCode

public final int hashCode()

Returns a hash code value for this object. The value is derived from the hash code of each of the record components.

Specified by:

hashCode in class Record

Returns:

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.

Specified by:

equals in class Record

Parameters:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

stream

public LogStreamId stream()

Returns the value of the stream record component.

Returns:

the value of the stream record component

firstOffset

public LogOffset firstOffset()

Returns the value of the firstOffset record component.

Returns:

the value of the firstOffset record component

lastOffset

public LogOffset lastOffset()

Returns the value of the lastOffset record component.

Returns:

the value of the lastOffset record component

recordCount

public int recordCount()

Returns the value of the recordCount record component.

Returns:

the value of the recordCount record component

bytesWritten

public long bytesWritten()

Returns the value of the bytesWritten record component.

Returns:

the value of the bytesWritten record component

fsynced

public boolean fsynced()

Returns the value of the fsynced record component.

Returns:

the value of the fsynced record component
