Function Documentation

Convert()

template<typename T >

T Convert

(

const wxString &

aValue

)

Function Convert converts a wxString to a generic type T.

Parameters

aValue

is a wxString containing the value that will be converted to type T.

Exceptions

XML_PARSER_ERROR

- an exception is thrown if the parsing fails or if the conversion to type T is unknown.

Definition at line 175 of file eagle_parser.h.

{
    throw XML_PARSER_ERROR( "Conversion failed. Unknown type." );
}

Convert< wxString >()

template<>

wxString Convert< wxString >

(

const wxString &

aValue

)

Definition at line 131 of file eagle_parser.cpp.

{
    return aValue;
}

ConvertArcCenter()

wxPoint ConvertArcCenter	(	const wxPoint &	aStart,
		const wxPoint &	aEnd,
		double	aAngle
	)

Convert an Eagle curve end to a KiCad center for S_ARC

Definition at line 265 of file eagle_parser.cpp.

{
    // Eagle give us start and end.
    // S_ARC wants start to give the center, and end to give the start.
    double dx = aEnd.x - aStart.x, dy = aEnd.y - aStart.y;
    wxPoint mid = ( aStart + aEnd ) / 2;

    double dlen = sqrt( dx*dx + dy*dy );

    if( !std::isnormal( dlen ) || !std::isnormal( aAngle ) )
    {
        THROW_IO_ERROR(
                wxString::Format( _( "Invalid Arc with radius %f and angle %f" ), dlen, aAngle ) );
    }

    double dist = dlen / ( 2 * tan( DEG2RAD( aAngle ) / 2 ) );

    wxPoint center(
        mid.x + dist * ( dy / dlen ),
        mid.y - dist * ( dx / dlen )
    );

    return center;
}

(

const wxString &

aNetName

)

Translates Eagle special characters to their counterparts in KiCad.

MapChildren()

NODE_MAP MapChildren

(

wxXmlNode *

aCurrentNode

)

Function MapChildren provides an easy access to the children of an XML node via their names.

Parameters

currentNode

is a pointer to a wxXmlNode, whose children will be mapped.

Returns

NODE_MAP - a map linking the name of each children to the children itself (via a wxXmlNode*)

Definition at line 241 of file eagle_parser.cpp.

{
    // Map node_name -> node_pointer
    NODE_MAP nodesMap;

    // Loop through all children mapping them in nodesMap
    if( aCurrentNode )
        aCurrentNode = aCurrentNode->GetChildren();

    while( aCurrentNode )
    {
        // Create a new pair in the map
        //      key: current node name
        //      value: current node pointer
        nodesMap[aCurrentNode->GetName()] = aCurrentNode;

        // Get next child
        aCurrentNode = aCurrentNode->GetNext();
    }
