Detailed Description

This class permits the creation and control of integer identifiers.

Constructor & Destructor Documentation

◆ Aspect_GenId() [1/2]

Aspect_GenId::Aspect_GenId ( )

Creates an available set of identifiers with the lower bound 0 and the upper bound INT_MAX / 2.

◆ Aspect_GenId() [2/2]

Aspect_GenId::Aspect_GenId ( const Standard_Integer  theLow,
const Standard_Integer  theUpper 
)

Creates an available set of identifiers with specified range. Raises IdentDefinitionError if theUpper is less than theLow.

Member Function Documentation

◆ Available()

Standard_Integer Aspect_GenId::Available ( ) const

Returns the number of available identifiers.

◆ Free() [1/2]

void Aspect_GenId::Free ( )

Free all identifiers - make the whole range available again.

◆ Free() [2/2]

void Aspect_GenId::Free ( const Standard_Integer  theId)

Free specified identifier. Warning - method has no protection against double-freeing!

◆ HasFree()

Standard_Boolean Aspect_GenId::HasFree ( ) const

Returns true if there are available identifiers in range.

◆ Lower()

Standard_Integer Aspect_GenId::Lower ( ) const

Returns the lower identifier in range.

◆ Next()

Standard_Integer Aspect_GenId::Next ( )

Returns the next available identifier. Warning: Raises IdentDefinitionError if all identifiers are busy.

◆ Upper()

Standard_Integer Aspect_GenId::Upper ( ) const

Returns the upper identifier in range.
