Explicit Operator

SWI-Prolog SbsSW.SwiPlCs

Swi-cs-pl - A CSharp class library to connect .NET languages with SWI-Prolog Explicit Operator

Converts the Prolog argument into a string which implies Prolog atoms and strings are converted to the represented text or throw a PlTypeException.

Declaration Syntax

Visual Basic

Visual C++

public static explicit operator string (
	PlTerm term
)

Public Shared Narrowing Operator CType ( _
	term As PlTerm _
) As String

static explicit operator String^ (
	PlTerm term
)

Parameters

term (PlTerm): A PlTerm that can be converted to a string

Return Value

A C# string

Remarks

Converts the Prolog argument using PL_get_chars() using the flags CVT_ALL|CVT_WRITE|BUF_RING, which implies Prolog atoms and strings are converted to the represented text or throw a PlTypeException.

If the above call return 0 PL_get_chars is called a second time with the flags CVT_ALL|CVT_WRITE|BUF_RING|REP_UTF8.

All other data is handed to write/1.

MM 23.11.2010: Meines Erachtens nach führt libpl.REP_MB die gewünschte Konvertierung nach UNICODE (MultiByte) durch. Passt aber nicht zur Doku!

Exceptions

Exception	Condition
PlTypeException	Throws a PlTypeException exception
PreconditionException	Is thrown if the operator is used on an uninitialized PlTerm
