Public Member Functions

mcSystemStepArray (long flags=mcSYSTEMSTEPARR_NOFLAGS)

virtual ~mcSystemStepArray ()

int math_RemoveIdenticSteps ()

Removes those contiguos (i.e.

int math_RemoveSimpleSteps ()

Removes from the array those contiguos steps which differ from the previous ones for a too small lenght, where the lenght is computed through the mcMathOrSystem::math_GetLenght() function and the threshold used is mcMathCore::GetThreshold().

void data_AddSys (mcMathOrSystem *pointer)

A specialized version of mcAbstractArray::math_Add.

void data_AddFinalSys (mcMathOrSystem *pointer)

Works like data_AddSys() but in the case that the mcSYSTEMSTEPARR_DISCARD_SIMPLE flag is set, this function forces anyway the addition of the given pointer.

void data_AddSysOnlyIfComplexEnough (mcMathOrSystem *pointer)

A "smart" version of data_AddSys(): before adding to the array the given mcMathOrSystem object, it checks if it is considered too "simple" to be added comparing it with the previous one.

void data_AddLine (const mcMathLine &p)

Adds a *copy* given mcMathLine into a new empty mcMathOrSystem using the data_AddSys function.

void data_AddKeyLine (const mcMathLine &p)

Works like data_AddLine but in the case that the mcSYSTEMSTEPARR_DISCARD_SIMPLE flag is set, this function forces anyway the addition of the given pointer.

void data_AddLineOnlyIfComplexEnough (const mcMathLine &p)

Like data_AddLine but uses the data_AddSysOnlyIfComplexEnough() function.

void data_MergeSystems (mcSystemStepArray &, int i)

Merges the given array of mcMathOrSystem.

void data_Check () const

Checks all the steps contained in the array.

const mcMathOrSystem * data_Get (int n) const

mcMathOrSystem * data_Get (int n)

const mcMathOrSystem * data_GetLast () const

mcMathOrSystem * data_GetLast ()

void math_AppendCombinationOf (const mcSystemStepArray &arr1, const mcSystemStepArray &arr2, mcLogicOperator lo)

Calls the mcMathOrSystem::math_AndMerge function (when lo == mcLO_AND) or mcMathOrSystem::math_OrMerge (when lo == mcLO_OR), on each i-th step of the first array with each i-th step of the second array, and then appends the result to this array.

wxString io_GetInlinedExpr () const

Returns a wxString containing the inlined expressions which describe the system.

Protected Member Functions

void data_Delete (int n)

Deletes the n-th step of this array.

Protected Attributes

long m_nFlags

Holds some info about array management.

Member Function Documentation

void mcSystemStepArray::data_AddFinalSys ( mcMathOrSystem * pointer )

Works like data_AddSys() but in the case that the mcSYSTEMSTEPARR_DISCARD_SIMPLE flag is set, this function forces anyway the addition of the given pointer.

Definition at line 410 of file Solver.cpp.
References mcAbstractArray::data_Add().

void mcSystemStepArray::data_AddKeyLine ( const mcMathLine & p )

Works like data_AddLine but in the case that the mcSYSTEMSTEPARR_DISCARD_SIMPLE flag is set, this function forces anyway the addition of the given pointer.
This function should be used only to add the *key* steps: those passages which must be absolutely retained...

void mcSystemStepArray::data_AddLine ( const mcMathLine & p )

Adds a *copy* given mcMathLine into a new empty mcMathOrSystem using the data_AddSys function.

void mcSystemStepArray::data_AddLineOnlyIfComplexEnough ( const mcMathLine & p )

void mcSystemStepArray::data_AddSysOnlyIfComplexEnough ( mcMathOrSystem * pointer )

A "smart" version of data_AddSys(): before adding to the array the given mcMathOrSystem object, it checks if it is considered too "simple" to be added comparing it with the previous one.
If it results too simple, it is deleted; otherwise, it is added to the array normally.
