virtual TypedHandle < const String > | toString () const | ||||||
Output a human-readable description of this Object to the given stream. Note that when overriding this method the return type must be TypedHandle<const String> rather then String::View. These two types are assignment compatible but not equivalent and declaring the override with String::View will not be a compatible override. coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toString method, to output Objects. If a managed String object is desired, the COH_TO_STRING macro can be used to build up a String from streamable contents and is generally how toString() will be implemented. Object::View vKey = ... Object::View vValue = ... std::cout << vKey << " = " << vValue << std::endl; String::View vs = COH_TO_STRING(vKey << " = " << vValue); The COH_TO_STRING macro is also the most common way to implement the toString method. For example: virtual TypedHandle<const String> Person::toString() const { return COH_TO_STRING("Name: " << f_sName << " SSN: " << f_nSSN); }

Construct an OctetArrayReadBuffer object from a portion of an octet Array.
vab | an Array of octets | |
of | the offset into the octet Array | |
cb | the number of octets to extract or npos for (vab->length - of) | |
fCopy | true to make a copy of the passed in Array |
IndexOutOfBoundsException | if of + cb is larger than vab->length | |
NullPointerException | if vab is NULL |
virtual void updateLength | ( | size32_t | cb | ) | [protected, virtual] |
Allow the length to be modified.
This method is provided for use by OctetArrayWriteBuffer only, and only for read buffers that it owns.
cb | the new length |
