CoderResult

open class CoderResult
kotlin.Any
   ↳ java.nio.charset.CoderResult

A description of the result state of a coder.

A charset coder, that is, either a decoder or an encoder, consumes bytes (or characters) from an input buffer, translates them, and writes the resulting characters (or bytes) to an output buffer. A coding process terminates for one of four categories of reasons, which are described by instances of this class:

  • Underflow is reported when there is no more input to be processed, or there is insufficient input and additional input is required. This condition is represented by the unique result object UNDERFLOW, whose isUnderflow method returns true.
  • Overflow is reported when there is insufficient room remaining in the output buffer. This condition is represented by the unique result object OVERFLOW, whose isOverflow method returns true.
  • A malformed-input error is reported when a sequence of input units is not well-formed. Such errors are described by instances of this class whose isMalformed method returns true and whose length method returns the length of the malformed sequence. There is one unique instance of this class for all malformed-input errors of a given length.
  • An unmappable-character error is reported when a sequence of input units denotes a character that cannot be represented in the output charset. Such errors are described by instances of this class whose isUnmappable method returns true and whose length method returns the length of the input sequence denoting the unmappable character. There is one unique instance of this class for all unmappable-character errors of a given length.

For convenience, the isError method returns true for result objects that describe malformed-input and unmappable-character errors but false for those that describe underflow or overflow conditions.

Summary

Public methods
open Boolean

Tells whether or not this object describes an error condition.

open Boolean

Tells whether or not this object describes a malformed-input error.

open Boolean

Tells whether or not this object describes an overflow condition.

open Boolean

Tells whether or not this object describes an underflow condition.

open Boolean

Tells whether or not this object describes an unmappable-character error.

open Int

Returns the length of the erroneous input described by this object  (optional operation).

open static CoderResult!

Static factory method that returns the unique object describing a malformed-input error of the given length.

open Unit

Throws an exception appropriate to the result described by this object.

open String

Returns a string describing this coder result.

open static CoderResult!

Static factory method that returns the unique result object describing an unmappable-character error of the given length.

Properties
static CoderResult!

Result object indicating overflow, meaning that there is insufficient room in the output buffer.

static CoderResult!

Result object indicating underflow, meaning that either the input buffer has been completely consumed or, if the input buffer is not yet empty, that additional input is required.
