Name

Description

getCharValue

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.

getSignedCharValue

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.

getUnsignedCharValue

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.

putCharValue

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.

putSignedCharValue

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.

putUnsignedCharValue

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.
