Detailed Description

Represents a field containing a function. A function is stored as an array of points.

Member Function Documentation

std::size_t fesa::FieldFunction::getMaxPoints ( ) const

void fesa::FieldFunction::setFieldValueAddress ( char *  pFV,
bool  initFieldsFlag 
)
protectedvirtual

Maps an address in shared memory or on the heap to the field value member of the field class.

Parameters
