class MKI_BLOCK_DOUBLE : public MKI_BLOCK_BASE

{

public:

double m_pData[];

};

This structure describes a data block storing double data types.

Element Description

Header

[MKI_BLOCK_HEADER] This structure contains general information about the data block. The ElemType element is to be set to MKI_DB_TYPE_DOUBLE (2).

Data

[double[]] List of data elements stored in the data block. The value must be between 1 and 8000 (inclusive).

MKD Syntax

This data block is used to store a given number of double values.

BlockOwner,BlockType,2,ElemCount,Data(1),...,Data(ElemCount);

Element Description

BlockOwner

[__int16] This value is a unique identification of the creator of the plug-in that created the data block. The value MKI_DB_OWNER_MK is reserved for use by Malz++Kassner, especially for objects and data blocks that are created and handled directly by the application. Valid range: 0 <= Value < 10000.

Third-party vendors that plan to implement a plug-in should contact Malz++Kassner to receive their unique identification (see Getting Your Private Owner ID).

BlockType

[__int16] This value is an internal identification of the data block. This value is used by the plug-in that created this object. For information about this value see the documentation of the plug-in which should include a description of all extended objects used.

Data blocks created by third-party vendors should use values between 1000 and 29999 (inclusive), the other values are reserved for direct use by Malz++Kassner.

ElemCount

[__int16] Number of values that are stored in this data block. The value must be between 1 and 4000 (inclusive).

Data(x)

[double] List of values, separated by commas, ended by a semicolon.

Comment

The following double data block types are predefined:

Data Block Type 100 (Constant)

A data block of type MKI_DB_ALL_CONSTANT (100) is used to store a single double, mainly in dimensions.

BlockOwner,100,2,1,Constant;

Constant

[double] Constant value.

Data Block Type 101 (Arc)

A data block of type MKI_DB_ALL_ARC (101) is used to store the direction of a circular or elliptical arc.

BlockOwner,101,2,1,Orientation;

Orientation

[double] Orientation of the arc. Positive values indicate counter-clockwise direction, negative values indicate clockwise direction.

Data Block Type 102 (Curve)

A data block of type MKI_DB_ALL_CURVE (102) is used to store the direction and the curvature of a circular arc inside a curve.

BlockOwner,102,2,1,Orientation,Curvature;

Orientation

[double] Orientation of the arc. Positive values indicate counter-clockwise direction, negative values indicate clockwise direction.

Curvature

[double] Curvature of the circular arc.
