Detailed Description

This component-private utility struct provides a namespace for a suite of functions used by BerUtil to implement BER encoding and decoding operations for byte values. Within the definition of this struct:

static int balber::BerUtil_CharacterImpUtil::getCharValue ( char *  value,
bsl::streambuf *  streamBuf,
int  length 
) [static]

Read the specified length number of bytes from the input sequence of the specified streamBuf and load to the specified value the interpretation of those bytes as the value of the contents octets of a BER-encoded integer according to the specification. Return 0 if successful, and a non-zero value otherwise. The operation succeeds if length bytes are successfully read from the input sequence of the streamBuf without the read position becoming unavailable, and the bytes read contain a valid representation of the contents octets of an integer value according to the specification. Note that the signedness of the interpreted integer value is the same as the signedness of char according to the current platform.

static int balber::BerUtil_CharacterImpUtil::getSignedCharValue ( signed char *  value,
bsl::streambuf *  streamBuf,
int  length 
) [static]

Read the specified length number of bytes from the input sequence of the specified streamBuf and load to the specified value the interpretation of those bytes as the value of the contents octets of a BER-encoded integer according to the specification. Return 0 if successful, and a non-zero value otherwise. The operation succeeds if length bytes are successfully read from the input sequence of the streamBuf without the read position becoming unavailable, and the bytes read contain a valid representation of the contents octets of an integer value according to the specification.

static int balber::BerUtil_CharacterImpUtil::getUnsignedCharValue ( unsigned char *  value,
bsl::streambuf *  streamBuf,
int  length 
) [static]

Read the specified length number of bytes from the input sequence of the specified streamBuf and load to the specified value the interpretation of those bytes as the value of the contents octets of a BER-encoded integer according to the specification. Return 0 if successful, and a non-zero value otherwise. The operation succeeds if length bytes are successfully read from the input sequence of the streamBuf without the read position becoming unavailable, and the bytes read contain a valid representation of the contents octets of an integer value according to the specification.

static int balber::BerUtil_CharacterImpUtil::putCharValue ( bsl::streambuf *  streamBuf,
char  value 
) [static]

Write the length and contents octets of the BER encoding of the specified integer value (as defined in the specification) to the output sequence of the specified streamBuf. Return 0 if successful, and a non-zero value otherwise. The operation succeeds if all bytes corresponding to the length and contents octets are written to the streamBuf without the write position becoming unavailable.

static int balber::BerUtil_CharacterImpUtil::putSignedCharValue ( bsl::streambuf *  streamBuf,
signed char  value 
) [static]

Write the length and contents octets of the BER encoding of the specified integer value (as defined in the specification) to the output sequence of the specified streamBuf. Return 0 if successful, and a non-zero value otherwise. The operation succeeds if all bytes corresponding to the length and contents octets are written to the streamBuf without the write position becoming unavailable.

static int balber::BerUtil_CharacterImpUtil::putUnsignedCharValue ( bsl::streambuf *  streamBuf,
unsigned char  value 
) [static]

Write the length and contents octets of the BER encoding of the specified integer value (as defined in the specification) to the output sequence of the specified streamBuf. Return 0 if successful, and a non-zero value otherwise. The operation succeeds if all bytes corresponding to the length and contents octets are written to the streamBuf without the write position becoming unavailable.
