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.
