Member Function Documentation

dup()

public_virtual SO0 * SO0::dup ( ) const

inlineoverrideprivatevirtual

Creates a new instance as copy following the PostScript definition.

Implements SO.

equal()

bool SO0::equal ( const SO *  p_other ) const

inlineoverrideprivatevirtual

Equality.

Equality means: For SOD, share_ptr<> points to the same object.
For SOA, share_ptr<> points to the same object, but empty arrays are equal nonetheless.
SO0 und SOM are always equal.
For SOO and SOo the function pointer must be the same.
Otherwise the value must be the same, even for SOS with shared_ptr<>.

Returns

bool ... true if the SO's are of the same type and equal

Implements SO.

opequal()

string SO0::opequal ( ) const

inlineoverrideprivatevirtual

For operators '=' and 'stack'.

Implements SO.

opequalequal()

string SO0::opequalequal ( Context &  ) const

inlineoverrideprivatevirtual

For operators '==' and 'pstack'.

Reimplemented from SO.

ot()

OTCode SO0::ot ( ) const

inlineoverrideprivatevirtual

Returns an OTCode.

A "manual" implementation of polymorphism, where C++-polymorphisms fail

Returns

char ... OTCode of the SO

Implements SO.
