class Encoding::InvalidByteSequenceError
Raised by Encoding
and String
methods when the string being transcoded contains a byte invalid for the either the source or target encoding.
Public Instance Methods
Source
static VALUE ecerr_destination_encoding(VALUE self) { return rb_attr_get(self, id_destination_encoding); }
Returns the destination encoding as an encoding object.
Source
static VALUE ecerr_destination_encoding_name(VALUE self) { return rb_attr_get(self, id_destination_encoding_name); }
Returns the destination encoding name as a string.
Source
static VALUE ecerr_error_bytes(VALUE self) { return rb_attr_get(self, id_error_bytes); }
Returns the discarded bytes when Encoding::InvalidByteSequenceError
occurs.
ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1") begin ec.convert("abc\xA1\xFFdef") rescue Encoding::InvalidByteSequenceError p $! #=> #<Encoding::InvalidByteSequenceError: "\xA1" followed by "\xFF" on EUC-JP> puts $!.error_bytes.dump #=> "\xA1" puts $!.readagain_bytes.dump #=> "\xFF" end
Source
static VALUE ecerr_incomplete_input(VALUE self) { return rb_attr_get(self, id_incomplete_input); }
Returns true if the invalid byte sequence error is caused by premature end of string.
ec = Encoding::Converter.new("EUC-JP", "ISO-8859-1") begin ec.convert("abc\xA1z") rescue Encoding::InvalidByteSequenceError p $! #=> #<Encoding::InvalidByteSequenceError: "\xA1" followed by "z" on EUC-JP> p $!.incomplete_input? #=> false end begin ec.convert("abc\xA1") ec.finish rescue Encoding::InvalidByteSequenceError p $! #=> #<Encoding::InvalidByteSequenceError: incomplete "\xA1" on EUC-JP> p $!.incomplete_input? #=> true end
Source
static VALUE ecerr_readagain_bytes(VALUE self) { return rb_attr_get(self, id_readagain_bytes); }
Returns the bytes to be read again when Encoding::InvalidByteSequenceError
occurs.
Source
static VALUE ecerr_source_encoding(VALUE self) { return rb_attr_get(self, id_source_encoding); }
Returns the source encoding as an encoding object.
Note that the result may not be equal to the source encoding of the encoding converter if the conversion has multiple steps.
ec = Encoding::Converter.new("ISO-8859-1", "EUC-JP") # ISO-8859-1 -> UTF-8 -> EUC-JP begin ec.convert("\xa0") # NO-BREAK SPACE, which is available in UTF-8 but not in EUC-JP. rescue Encoding::UndefinedConversionError p $!.source_encoding #=> #<Encoding:UTF-8> p $!.destination_encoding #=> #<Encoding:EUC-JP> p $!.source_encoding_name #=> "UTF-8" p $!.destination_encoding_name #=> "EUC-JP" end
Source
static VALUE ecerr_source_encoding_name(VALUE self) { return rb_attr_get(self, id_source_encoding_name); }
Returns the source encoding name as a string.
