PositiveIntOutputs

An FST Outputs implementation where each output is a non-negative long value.

Types

open override val noOutput: Long

NOTE: this output is compared with == so you must ensure that all methods return the single object if it's really no output

open override fun add(prefix: Long, output: Long): Long

Eg add("foo", "bar") -> "foobar"

open override fun common(output1: Long, output2: Long): Long

Eg common("foobar", "food") -> "foo"

fun merge(first: Long, second: Long): Long

open override fun outputToString(output: Long): String

open override fun ramBytesUsed(output: Long): Long

Return memory usage for the provided output.

open override fun read(input: DataInput): Long

Decode an output value previously written with .write.

Decode an output value previously written with .writeFinalOutput. By default this just calls .read.

Skip the output previously written with .writeFinalOutput; defaults to just calling .readFinalOutput and discarding the result.

Skip the output; defaults to just calling .read and discarding the result.

open override fun subtract(output: Long, inc: Long): Long

Eg subtract("foobar", "foo") -> "bar"

open override fun toString(): String

open override fun write(output: Long, out: DataOutput)

Encode an output value into a DataOutput.

Encode an final node output value into a DataOutput. By default this just calls .write.
