Member Function Documentation

addLiteral()

void anna::MultiRangeExpression::addLiteral ( const char *  l )

inline

Accumulates the provided literal over the stored literal You could simplify with simplifyLiteral, because perhaps there is overlapping between current literal and provided one.

Parameters

l	Literal to be added

                                  {
    if(!l) return;

    if(std::string(l) != "") {
      a_literal += ",";
      a_literal += l;
    }

    refresh();
  }

contain()

bool anna::MultiRangeExpression::contain ( const unsigned int &  value ) const

inline

Returns true if the value provided is contained in the multirange expression literal

Parameters

value

Value to be tested

Returns

True or false

{ return (a_data.find(value) != a_data.end()); }

getExpandedLiteral()

std::string anna::MultiRangeExpression::getExpandedLiteral

(

void

)

const

Gets expanded representation for stored literal. E.g.: '1-3,8,10' => '1,2,3,7,8,10'

Returns

Expanded literal

getLiteral()

const char* anna::MultiRangeExpression::getLiteral ( void  ) const

inline

Gets the configured literal by mean setLiteral or addLiteral

Returns

Literal

{ return a_literal.c_str(); }

Here is the call graph for this function:

setLiteral()

void anna::MultiRangeExpression::setLiteral ( const char *  l )

inline

Configures a new literal

Parameters

l	Literal to be stored

                                  {
    a_literal = l ? l : "";
    refresh();
  }

simplifyLiteral()

const char* anna::MultiRangeExpression::simplifyLiteral

(

void

)

Simplify stored literal. E.g.: '1,1,1,2,3,7,8,10' => '1-3,8,10' and returns it.

Returns

Simplified literal
