Detailed Description

The context of execution.

Invariant

process level >= 0

Constructor & Destructor Documentation

Context()

Context::Context

(

)

Ctor.

Pushes and initializes a user dictionary, a crypto dictionary, and a system dictionary onto the dictionary stack. Sets up empty stacks and all Context parameters.

Postcondition

mindictstack_ == ds_.getSize()

~Context()

Context::~Context ( )

virtual

Dtor.

Frees all resources to enable a comprehensive memory leak analysis upon program exit.

Member Function Documentation

getCout()

std::ostream & Context::getCout ( )

inline

Getter for cout_.

We use the Interpreter stream until a split of streams for multiple Contexts will be implemented.

invariant()

bool Context::invariant ( ) const

inlineoverrideprotectedvirtualnoexcept

Checks class invariants.

Returns

bool ... Indicates whether the class invariants are maintained.

Reimplemented from DbC.

Member Data Documentation

angularunit_

AngularUnit Context::angularunit_ = DEG

private

Context Property.

The angular unit for trigonometric functions.

kryptodictmap_

const std::map< const char *, Context::core * > Context::kryptodictmap_

staticprivate

Initial value:

= {
  
  { "dictstack$", &sox_dictstack$ },
  { "__endstack", &sox___endstack }, { "$", &sox___endstack },
  { "execstack$", &sox_execstack$ },
  { "gcd", &sox_gcd },               { "ggT", &sox_gcd },
  { "index$", &sox_index$ },
  { "is$", &sox_is$ },
  { "lcm", &sox_lcm },               { "kgV", &sox_lcm },
  { "pop$", &sox_pop$ },
  { "push$", &sox_push$ },
  { "xgcd", &sox_xgcd },             { "xggT", &sox_xgcd }
}

Maps SON data to SOO data for the kryptodict.

size_t Context::maxopeelevel_ = 2

private

Context Property.

A maximum for the nesting level of printed SOA, SOD and SOK in the "OPerator Equal Equal".

realprecision_

size_t Context::realprecision_ = 10

private

Context Property.

Precison of printf() output of SOR values.
