Detailed Description

Repository of attribute values.

Ipe documents can use symbolic attributes, such as 'normal', 'fat', or 'thin' for line thickness, or 'red', 'navy', 'turquoise' for color, as well as absolute attributes such as (0.5,0.5,0.5) for medium gray. To avoid storing these very common values hundreds of times, IpeRepository keeps a repository of all the non-scalar attribute values in the document. Inside IpeObject's attributes are represented as integer indices into the repository.

There are currently the following symbolic attributes:

These attributes can be symbolic, but the value is stored inside the IpeAttribute:

IpeRepository::IpeRepository (   ) 
 

Constructor.

Member Function Documentation

IpeString IpeRepository::ToString (  IpeAttribute  attr  )  const
 

Return string with given index.

Both positive (dash style) and negativ (symbolic name) index is possible.

IpeColor IpeRepository::ToColor (  IpeAttribute  index  )  const
 

Return color with given index.

IpeFixed IpeRepository::ToScalar (  IpeAttribute  index  )  const
 

Return value with given index.

IpeVector IpeRepository::ToVector (  IpeAttribute  index  )  const
 

Return vector with given index.

IpeAttribute IpeRepository::ToAttribute (  const IpeColor &  color  ) 
 

Lookup a color (add it if it doesn't exist yet), and return index.

IpeAttribute IpeRepository::ToAttribute (  IpeKind  kind,
IpeFixed  value
) 
 

Lookup value (add it if it doesn't exist yet), and return index.

IpeAttribute IpeRepository::ToAttribute (  IpeKind  kind,
const IpeVector &  vec
) 
 

Lookup vector (add it if it doesn't exist yet), and return index.

IpeAttribute IpeRepository::MakeColor (  IpeString  str  ) 
 

Create an IpeAttribute representing the color described.

Empty string creates null color, string starting with a letter creates a symbolic color (includes special case "void"), otherwise absolute color.

IpeAttribute IpeRepository::MakeString (  IpeKind  kind,
IpeString  str
) 
 

Construct absolute value (which is a string).

IpeAttribute IpeRepository::MakeDashStyle (  IpeString  str  ) 
 

Construct dash style attribute from string.

Empty string creates null value, string starting with '[' creates an absolute dash style, otherwise symbolic dash style (including the special case "solid").

IpeAttribute IpeRepository::MakeTextSize (  IpeString  str  ) 
 

Construct text size attribute from string.

Empty string creates null value, string starting with digit creates an numeric absolute value, string starting with letter creates symbolic text size, anything else creates absolute (string) text size.

IpeAttribute IpeRepository::MakeScalar (  IpeKind  kind,
IpeString  str
) 
 

Construct scalar attribute from string.

Empty string creates null value, string starting with non-letter creates an absolute value, string starting with letter creates symbolic value.

IpeAttribute IpeRepository::MakeVector (  IpeKind  kind,
IpeString  str
) 
 

Construct vector attribute from string.

Empty string creates null value, string starting with non-letter creates an absolute value, string starting with letter creates symbolic value.

IpeAttribute IpeRepository::MakeSymbol (  IpeKind  kind,
IpeString  str
) 
 

Construct symbolic attribute from string.

Empty string creates null value, anything else creates symbolic value.

IpeString IpeRepository::String (  IpeAttribute  attr  )  const
 

Return string representation of attribute (symbolic or absolute).
