Method Detail

apply

public Integer apply(@Nonnull
                     Long timestamp)

Description copied from class: FieldPartitioner

Apply the partition function to the given value.

The type of value must be compatible with the field partitioner implementation. Normally, this is validated at the time of initial configuration rather than at runtime.

Specified by:

apply in interface com.google.common.base.Function<Long,Integer>

valueToString

@Deprecated
public String valueToString(Integer value)

Deprecated.

Description copied from class: FieldPartitioner

Retrieve the value for the field formatted as a String. By default, this is the object's Object.toString() representation, but some FieldPartitioners may choose to provide a different representation.

Overrides:

valueToString in class FieldPartitioner<Long,Integer>

valueFromString

@Deprecated
public Integer valueFromString(String stringValue)

Deprecated.

Description copied from class: FieldPartitioner

Retrieve the value for the field from the string representation.

Specified by:

valueFromString in class FieldPartitioner<Long,Integer>
