Detailed Description

TCommandSet is a non-view class for handling command sets.

Member functions are provided for enabling and disabling commands and for testing for the presence of a given command. Several operators are overloaded to allow natural testing for equality and so on.

Note: this object can only handle commands whose code is within 0 and 255. Only commands in this range may be disabled.

Constructor & Destructor Documentation

Constructor. Creates and clears a command set.

TCommandSet::TCommandSet ( const TCommandSet & tc )

Constructor. This form creates a command set and initializes it from the `tc' argument.

Member Function Documentation

void TCommandSet::disableCmd ( const TCommandSet & tc )

Removes all commands in set `tc' from this command set.

void TCommandSet::disableCmd ( int cmd )

Removes command `cmd' from the set. Referenced by operator-=().

void TCommandSet::enableCmd ( const TCommandSet & tc )

Adds all commands in set `tc' to this command set.

void TCommandSet::enableCmd ( int cmd )

Adds command `cmd' to the set. Referenced by operator+=().

Boolean TCommandSet::has ( int cmd )

Returns True if command `cmd' is in the set.

Boolean TCommandSet::isEmpty ( )

Returns True if the command set is empty.

TCommandSet & TCommandSet::operator &= ( const TCommandSet & tc )

Calculates the intersection of this set and the `tc' set. The resulting set is the largest set which contains commands present in both sets. Returns a reference to this object.

void TCommandSet::operator+= ( const TCommandSet & tc ) [inline]

Adds all commands in set `tc' to this command set. Definition at line 709 of file views.h.

void TCommandSet::operator+= ( int cmd ) [inline]

Adds command `cmd' to the set. Definition at line 699 of file views.h.

void TCommandSet::operator-= ( const TCommandSet & tc ) [inline]

Removes all commands in set `tc' from this command set. Definition at line 714 of file views.h.

void TCommandSet::operator-= ( int cmd ) [inline]

Removes command `cmd' from the set. Definition at line 704 of file views.h.

TCommandSet & TCommandSet::operator|= ( const TCommandSet & tc )

Calculates the union of this set and the `tc' set. The resulting set is the smallest set which contains commands present in either sets. Returns a reference to this object.

Friends And Related Function Documentation

TCommandSet operator & ( const TCommandSet &, const TCommandSet & ) [friend]

Calculates the intersection of this set and the `tc' set. The resulting set is the largest set which contains commands present in both sets. Returns the resulting set.

int operator!= ( const TCommandSet & tc1, const TCommandSet & tc2 ) [friend]

Returns 1 if the sets `tc1' and `tc2' are not equal. Otherwise returns 0. Definition at line 719 of file views.h.

int operator== ( const TCommandSet & tc1, const TCommandSet & tc2 ) [friend]

Returns 1 if the sets `tc1' and `tc2' are equal. Otherwise returns 0.

TCommandSet operator| ( const TCommandSet &, const TCommandSet & ) [friend]

Calculates the union of this set and the `tc' set. The resulting set is the smallest set which contains commands present in either sets. Returns the resulting set.
