errnoFromException

public static jnr.constants.platform.Errno errnoFromException(Throwable t)

This method attempts to produce an Errno value for the given exception. Many low-level operations wrapped by the JDK will raise IOException or subclasses of it when there's a system- level error. In most cases, the only way to determine the cause of the IOException is by inspecting its contents, usually by checking the error message string. This is obviously fragile and breaks on platforms localized to languages other than English, so we also try as much as possible to detect the cause of the error by its actual type (if it is indeed a specialized subtype of IOException).

Parameters:

t - the exception to convert to an Errno

Returns:

the resulting Errno value, or null if none could be determined.

newIOErrorFromException

public static RaiseException newIOErrorFromException(Ruby runtime,
 IOException ex)

Construct an appropriate error (which may ultimately not be an IOError) for a given IOException. If this method is used on an exception which can't be translated to a Ruby error using newErrorFromException(Ruby, Throwable) then a RuntimeError will be returned, due to the unhandled exception type.

Parameters:

runtime - the current runtime

ex - the exception to translate into a Ruby error

Returns:

a RaiseException subtype instance appropriate for the given exception

newErrorFromException

public static Throwable newErrorFromException(Ruby runtime,
 Throwable t,
 Function<Throwable,Throwable> els)

Return a Ruby-friendly Throwable for a given Throwable. The following translations will be attempted in order:

• if the Throwable is already a Ruby exception type, return it as-is
• convert to a Ruby Errno exception via errnoFromException(Throwable)
• convert to a Ruby IOError if the exception is a java.io.IOException
• using the provided function as a fallback transformation

Parameters:

runtime - the current runtime

t - the exception to translate into a Ruby error

els - a fallback function if the exception cannot be translated

Returns:

a RaiseException subtype instance appropriate for the given exception

newErrorFromException

public static Throwable newErrorFromException(Ruby runtime,
 Throwable t)

Simplified form of Ruby#newErrorFromException with no default function.

Parameters:

runtime - the current runtime

t - the exception to translate into a Ruby error

Returns:

a RaiseException subtype instance appropriate for the given exception

throwErrorFromException

public static void throwErrorFromException(Ruby runtime,
 Throwable t)

Throw an appropriate Ruby-friendly error or exception for a given Java exception. This method will first attempt to translate the exception into a Ruby error using newErrorFromException(Ruby, Throwable, Function). Failing that, it will raise the original Java exception as-is.

Parameters:

runtime - the current runtime

t - the exception to raise as an error, if appropriate, or as itself otherwise

calculateBufferLength

public static int calculateBufferLength(int length)

Calculate a buffer length based on the required length, expanding by 1.5x or to the maximum array size.

Parameters:

length - the required length

Returns:

a larger buffer length with extra room for growth, or else the max array size

Throws:

OutOfMemoryError - if the requested length is greated than the max array size

calculateBufferLength

public static int calculateBufferLength(Ruby runtime,
 int length)

Same as calculateBufferLength(int) but raises a Ruby ArgumentError.

multiplyBufferLength

public static int multiplyBufferLength(Ruby runtime,

Deprecated.

multiplyBufferLength

public static int multiplyBufferLength(ThreadContext context,
 int base,
 int multiplier)

Calculate a buffer length based on a base size and a multiplier. If the resulting size exceeds MAX_ARRAY_SIZE, an ArgumentError will be thrown, similar to when asking the JVM to allocate a too-large array.

Parameters:

context - the thread context

base - the base size

multiplier - the multiplier

Returns:

the multiplied size, if valid

Throws:

ArgumentError - if the requested length is greated than the max array size

addBufferLength

@Deprecated(since="10.0")
public static int addBufferLength(Ruby runtime,
 int base,
 int extra)

Deprecated.

addBufferLength

public static int addBufferLength(ThreadContext context,
 int base,
 int extra)

Calculate a buffer length based on a base size and a extra size. If the resulting size exceeds MAX_ARRAY_SIZE and the extra size is nonzero, use the MAX_ARRAY_SIZE as the buffer length.

Parameters:

context - the current thread context

base - the base size

extra - the extra buffer size

Returns:

the combined buffer size, or MAX_ARRAY_SIZE

Throws:

ArgumentError - if the original or combined size cannot be accommodated by MAX_ARRAY_SIZE

validateBufferLength

public static int validateBufferLength(Ruby runtime,
 long length)

validateBufferLength

public static int validateBufferLength(ThreadContext context,

The protocol for super method invocation is a bit complicated in Ruby.

symbolBytesToString

public static String symbolBytesToString(ByteList value)

Decode the given value to a Java string using the following rules: * If the string is all US-ASCII characters, it will be decoded as US-ASCII. * If the string is a unicode encoding, it will be decoded as such. * If the string is any other encoding, it will be encoded as raw bytes using ISO-8859-1. This allows non-unicode, non-US-ASCII encodings to be represented in the symbol table as their raw versions, but properly decodes unicode- encoded strings.

Parameters:

value - the value to decode

Returns:

the resulting symbol string
