Member Function Documentation

YCPValue YECompare::evaluate ( bool  cse = false )

virtual

Execute YCP code to get the resulting YCPValue. Every inherited class of YCode should reimplement this method.

Returns

YCPValue after executing the code

Parameters

cse	should the evaluation be done for parse time evaluation (i.e. constant subexpression elimination)

Reimplemented from YCode.

virtual ykind YECompare::kind ( ) const

inlinevirtual

Kind of this YCode. This method must be reimplemented in the inherited classes.

Returns

the YCode kind

Implements YCode.

References YCode::yeCompare.

YECompare::REP_BODY ( YECompare  )

private

std::ostream & YECompare::toStream ( std::ostream &  str ) const

virtual

Write YCP code to a byte stream (bytecode implementation). Every class inheriting from YCode must reimplement this method.

Parameters

str	byte stream to store into

Returns

byte stream for chaining writing bytecode (str)

Implements YCode.

References m_left, m_op, m_right, and YCode::toStream().

string YECompare::toString ( void  ) const

virtual

Return ASCII represtation of this YCP code.

Returns

ASCII string representation

Reimplemented from YCode.

References compare_op_string(), m_left, m_op, and m_right.

std::ostream & YECompare::toXml ( std::ostream &  str, int  indent  ) const

virtual

Write YCP code as XML representation. Every class inheriting from YCode must reimplement this method.

Parameters

str	string stream to store into
indend	indentation level for pretty print

Returns

string stream for chaining writing XML (str)

Implements YCode.

References YCode::commentToXml(), compare_op_string(), m_left, m_op, m_right, and Xmlcode::xmlify().

constTypePtr YECompare::type ( ) const

inlinevirtual

Return type of this YCP code (interesting mostly for function calls).

Returns

type of the value to be returned after calling evaluate

Reimplemented from YCode.

References Type::Boolean.
