CNKPropertyInfo Information other than the actual data is stored and exchanged using

properties. A property is a name/value pair where the name uniquely

identifies the piece of information being stored, and the value is the

information being stored.

The methods

CNKObj::setProperty and CNKObj::getProperty are

used to set and get property values for an object.

One use for this is to pass parameters from Java to the C++ code

implementing the component. It may also be used to communicate

results such as numeric summaries back to the Java code after

computation is complete.

A property is stored in a

CNKPropertyInfo object. CNKPropertyInfo

is defined in CNKPropertyInfo.h with the following methods:

CNKPropertyInfo::

const char* getPropName();

int isPropName(char* name);

getPropName()

returns the property name for this object.

isPropName(char* name) compares this string to the argument

"name", returning true (non-zero) if they are the same.

CNKPropertyInfo::

virtual long getPropAsINT32();

virtual void setPropAsINT32(long val);

virtual INT64 getPropAsINT64();

virtual void setPropAsINT64(INT64 val);

double getPropAsDouble();

void setPropAsDouble(double val);

int getPropAsLogical();

void setPropAsLogical(int val);

const char* getPropAsString();

void setPropAsString(const char* val);

These methods get/set the argument to a single long, double, etc.

value.

CNKPropertyInfo::

CNKBuf* getPropAsCNKBuf();

void setPropAsCNKBuf(CNKBuf* buf);

CNKProc* getPropAsCNKProc();

void setPropAsCNKProc(CNKProc* proc);
