Constructor & Destructor Documentation

Context()

Context::Context

(

)

Ctor.

Pushes and initializes a user dictionary, a leo 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.

property_statistics()

void Context::property_statistics

(

)

Snapshot of Context properties to cout.

stack_statistics()

void Context::stack_statistics

(

)

Snapshot of stacks to cout.

status_statistics()

void Context::status_statistics

(

)

Snapshot of Context state to cout.
