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

inline

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

inline

Returns true if there are available identifiers in range.

Lower()

Standard_Integer Aspect_GenId::Lower ( void  ) const

inline

Returns the lower identifier in range.

Next() [1/2]

Standard_Integer Aspect_GenId::Next

(

)

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

Next() [2/2]

Standard_Boolean Aspect_GenId::Next

(

Standard_Integer &

theId

)

Generates the next available identifier.

Parameters

theId

[out] generated identifier

Returns

FALSE if all identifiers are busy.

Upper()

Standard_Integer Aspect_GenId::Upper ( void  ) const

inline

Returns the upper identifier in range.
