CoderResult

public class CoderResult
extends Object

java.lang.Object
↳	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

Fields
`public static final CoderResult`	`OVERFLOW` Result object indicating overflow, meaning that there is insufficient room in the output buffer.
`public static final CoderResult`	`UNDERFLOW` 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.

Public methods
`boolean`	`isError()` Tells whether or not this object describes an error condition.
`boolean`	`isMalformed()` Tells whether or not this object describes a malformed-input error.
`boolean`	`isOverflow()` Tells whether or not this object describes an overflow condition.
`boolean`	`isUnderflow()` Tells whether or not this object describes an underflow condition.
`boolean`	`isUnmappable()` Tells whether or not this object describes an unmappable-character error.
`int`	`length()` Returns the length of the erroneous input described by this object (optional operation).
`static CoderResult`	`malformedForLength(int length)` Static factory method that returns the unique object describing a malformed-input error of the given length.
`void`	`throwException()` Throws an exception appropriate to the result described by this object.
`String`	`toString()` Returns a string describing this coder result.
`static CoderResult`	`unmappableForLength(int length)` Static factory method that returns the unique result object describing an unmappable-character error of the given length.

Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Fields
