ShardRoute

public ShardRoute(ShardKey key,
 String shardId,
 int partitionId,
 ObjectRef target,
 Map<String,String> metadata)

Creates immutable route metadata.

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.

key

public ShardKey key()

Returns the value of the key record component.

Returns:

the value of the key record component

shardId

public String shardId()

Returns the value of the shardId record component.

Returns:

the value of the shardId record component

partitionId

public int partitionId()

Returns the value of the partitionId record component.

Returns:

the value of the partitionId record component

target

public ObjectRef target()

Returns the value of the target record component.

Returns:

the value of the target record component

metadata

public Map<String,String> metadata()

Returns the value of the metadata record component.

Returns:

the value of the metadata record component
