Detailed Description

The Bool class is an abstraction for the boolean data type.

It's not meant to be a replacement for bool. Use it if you need a type that supports toString(), readObject(), or writeObject(). It's also useful for preventing implicit conversion of char*->bool. Using it can make overloading functions safer (ie it'll be less likely the compiler will pick the wrong overload.)

Member Function Documentation

OWBI1::Bool::operator bool (   )  const [inline]

Returns: The bool value of this Bool object. Definition at line 108 of file OWBI1_Bool.hpp.

bool OWBI1::Bool::operator! (   )  const [inline]

Negation operator. Returns: true if this Bool operator has a value of false. Definition at line 113 of file OWBI1_Bool.hpp.

bool OWBI1::Bool::operator!= (  const Bool &  arg  )  const [inline]

Inequality operator. Parameters: arg  The Bool object to compare this one with. Returns: true If the given Bool object is not equal to this one. Otherwise false Definition at line 104 of file OWBI1_Bool.hpp. References m_val.

bool OWBI1::Bool::operator!= (  const bool  arg  )  const [inline]

Inequality operator. Parameters: arg  bool value to compare this Bool object against. Returns: true If the given bool value is not equal to this one. Otherwise false Definition at line 97 of file OWBI1_Bool.hpp.

Bool& OWBI1::Bool::operator= (  const Bool &  arg  )  [inline]

Assignment operator. Parameters: arg  The Bool to assign to this one. Returns: A reference to this object after the assignment has been made. Definition at line 76 of file OWBI1_Bool.hpp. References m_val.

bool OWBI1::Bool::operator== (  const Bool &  arg  )  const [inline]

Equality operator. Parameters: arg  The Bool object to compare this one with. Returns: true If the given Bool object is equal to this one. Otherwise false Definition at line 90 of file OWBI1_Bool.hpp. References m_val.

bool OWBI1::Bool::operator== (  const bool  arg  )  const [inline]

Equality operator. Parameters: arg  bool value to compare this Bool object against. Returns: true If the given bool value is equal to this one. Otherwise false Definition at line 83 of file OWBI1_Bool.hpp.

void OWBI1::Bool::readObject (  std::istream &  istrm  )

Read this object from an input stream. Parameters: istrm  The input stream to read this object from.

String OWBI1::Bool::toString (   )  const

Returns: The string representation of this object. If this object contains a true value, the "true" is returned. Otherwise "false" is returned. Definition at line 70 of file OWBI1_Bool.cpp. References m_val. Referenced by OWBI1::StringBuffer::operator+=().

void OWBI1::Bool::writeObject (  std::ostream &  ostrm  )  const

Write this object to an output stream. Parameters: ostrm  The output stream to write this object to.

bool operator< (  const Bool &  b1, const Bool &  b2 )  [friend]

Less than operator (friend function). Parameters: b1  The first Bool object to use in the comparison. b2  The second Bool object to use in the comparison. Returns: true if b1 is less than b2. Otherwise false. Definition at line 135 of file OWBI1_Bool.hpp.
