virtual void | readExternal (PofReader::Handle hIn) |
virtual void | writeExternal (PofWriter::Handle hOut) const |
virtual bool | equals (Object::View v) const |
Compare the AbstractCompositeExtractor with another object to determine equality. | |
virtual size32_t | hashCode () const |
Return a hash code value for the Object. This method is supported for the benefit of hash-based containers.
The general contract of
The default implementation is identity based.

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); }

Protected Member Functions | |
AbstractCompositeExtractor () | |
Default constructor (necessary for the PortableObject interface). | |
AbstractCompositeExtractor (ObjectArray::View vaExtractor) | |
Construct a AbstractCompositeExtractor based on the specified ValueExtractor array. | |
AbstractCompositeExtractor (ValueExtractor::View vE1, ValueExtractor::View vE2) | |
Construct a AbstractCompositeExtractor based on two ValueExtractors. | |
Protected Attributes | |
FinalView< ObjectArray > | f_vaExtractor |
The ValueExtractor array. |
AbstractCompositeExtractor | ( | ObjectArray::View | vaExtractor | ) | [protected] |
Construct a AbstractCompositeExtractor based on the specified ValueExtractor array.
vaExtractor | the ValueExtractor array |
AbstractCompositeExtractor | ( | ValueExtractor::View | vE1, | |
ValueExtractor::View | vE2 | |||
) | [protected] |
Construct a AbstractCompositeExtractor based on two ValueExtractors.
vaE1 | the first ValueExtractor | |
vaE2 | the second ValueExtractor |
virtual bool equals | ( | Object::View | v | ) | const [virtual] |
Compare the AbstractCompositeExtractor with another object to determine equality.
Two AbstractCompositeExtractor objects are considered equal iff they belong to the same class and their underlying ValueExtractor arrays are deep-equal.
