Detailed Description

Codeset translation routines common to both Output and Input CDR streams.

This class is a base class for defining codeset translation routines to handle the character set translations required by both CDR Input streams and CDR Output streams.

Translators are reference counted. This allows for stateful as well as stateless translators. Stateless translators will be allocated once whereas CDR Streams own their own copy of a stateful translator.

int ACE_Char_Codeset_Translator::adjust ( ACE_OutputCDR out,
size_t  size,
size_t  align,
char *&  buf 
)
inlineprotected

Exposes the stream implementation of <adjust>, this is useful in many cases to minimize memory allocations during marshaling. On success buf will contain a contiguous area in the CDR stream that can hold size bytes aligned to align. Results

void ACE_Char_Codeset_Translator::good_bit ( ACE_OutputCDR out,
bool  bit 
)
inlineprotected

Used by derived classes to set errors in the CDR stream.

ACE_CDR::Octet ACE_Char_Codeset_Translator::major_version ( ACE_InputCDR input)
inlineprotected

Obtain the CDR Stream's major & minor version values.

pure virtual
ACE_CDR::Boolean ACE_Char_Codeset_Translator::read_1 ( ACE_InputCDR input,
ACE_CDR::Octet x 
)
inlineprotected

Children have access to low-level routines because they cannot use read_char or something similar (it would recurse).

ACE_CDR::Boolean ACE_Char_Codeset_Translator::read_array ( ACE_InputCDR input,
void *  x,
size_t  size,
size_t  align,
ACE_CDR::ULong  length 
)
inlineprotected

Efficiently read length elements of size size each from input into x; the data must be aligned to align.

virtual ACE_CDR::Boolean ACE_Char_Codeset_Translator::read_char ( ACE_InputCDR ,
ACE_CDR::Char  
)
pure virtual

Read a single character from the stream, converting from the stream codeset to the native codeset

virtual ACE_CDR::Boolean ACE_Char_Codeset_Translator::read_char_array ( ACE_InputCDR ,
ACE_CDR::Char ,
ACE_CDR::ULong   
)
pure virtual

Read an array of characters from the stream, converting the characters from the stream codeset to the native codeset.

virtual ACE_CDR::Boolean ACE_Char_Codeset_Translator::read_string ( ACE_InputCDR ,
ACE_CDR::Char *&   
)
pure virtual

Read a string from the stream, including the length, converting the characters from the stream codeset to the native codeset

virtual ACE_CDR::ULong ACE_Char_Codeset_Translator::tcs ( )
pure virtual
ACE_CDR::Boolean ACE_Char_Codeset_Translator::write_1 ( ACE_OutputCDR output,
const ACE_CDR::Octet x 
)
inlineprotected
ACE_CDR::Boolean ACE_Char_Codeset_Translator::write_array ( ACE_OutputCDR output,
const void *  x,
size_t  size,
size_t  align,
ACE_CDR::ULong  length 
)
inlineprotected

Efficiently write length elements of size size from <x> into <output>. Before inserting the elements enough padding is added to ensure that the elements will be aligned to <align> in the stream.

virtual ACE_CDR::Boolean ACE_Char_Codeset_Translator::write_char ( ACE_OutputCDR ,
ACE_CDR::Char   
)
pure virtual

Write a single character to the stream, converting from the native codeset to the stream codeset

virtual ACE_CDR::Boolean ACE_Char_Codeset_Translator::write_char_array ( ACE_OutputCDR ,
const ACE_CDR::Char ,
ACE_CDR::ULong   
)
pure virtual

Write an array of characters to the stream, converting from the native codeset to the stream codeset

virtual ACE_CDR::Boolean ACE_Char_Codeset_Translator::write_string ( ACE_OutputCDR ,
ACE_CDR::ULong  ,
const ACE_CDR::Char  
)
pure virtual

Write a string to the stream, including the length, converting from the native codeset to the stream codeset
