Constructor Details

SnapshotMetadata

public SnapshotMetadata(long snapshotIndex,
 long snapshotTerm,
 int dataStructureCount,
 long totalSizeBytes,
 long compressedSizeBytes,
 long createdAt,
 long checksum)

Creates an instance of a SnapshotMetadata record class.

Parameters:

snapshotIndex - the value for the snapshotIndex record component

snapshotTerm - the value for the snapshotTerm record component

dataStructureCount - the value for the dataStructureCount record component

totalSizeBytes - the value for the totalSizeBytes record component

compressedSizeBytes - the value for the compressedSizeBytes record component

createdAt - the value for the createdAt record component

checksum - the value for the checksum record component

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. All components in this record class 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.

snapshotIndex

public long snapshotIndex()

Returns the value of the snapshotIndex record component.

Returns:

the value of the snapshotIndex record component

snapshotTerm

public long snapshotTerm()

Returns the value of the snapshotTerm record component.

Returns:

the value of the snapshotTerm record component

dataStructureCount

public int dataStructureCount()

Returns the value of the dataStructureCount record component.

Returns:

the value of the dataStructureCount record component

totalSizeBytes

public long totalSizeBytes()

Returns the value of the totalSizeBytes record component.

Returns:

the value of the totalSizeBytes record component

compressedSizeBytes

public long compressedSizeBytes()

Returns the value of the compressedSizeBytes record component.

Returns:

the value of the compressedSizeBytes record component

createdAt

public long createdAt()

Returns the value of the createdAt record component.

Returns:

the value of the createdAt record component

checksum

public long checksum()

Returns the value of the checksum record component.

Returns:

the value of the checksum record component
