Member Function Documentation

YCPValue YStatement::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.

Reimplemented in YSSwitch, YSFilename, YSImport, YSInclude, YSTextdomain, YSDo, YSRepeat, YSWhile, YSIf, YSBracket, YSAssign, YSFunction, YSTypedef, YSReturn, YSBlock, YSExpression, YSContinue, and YSBreak.

yes

YStatement::REP_BODY ( YStatement  )

private

std::ostream & YStatement::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.

Reimplemented in YSSwitch, YSFilename, YSImport, YSInclude, YSTextdomain, YSDo, YSRepeat, YSWhile, YSIf, YSBracket, YSAssign, YSFunction, YSTypedef, YSReturn, YSBlock, YSExpression, YSContinue, and YSBreak.

References YCode::kind(), m_line, Bytecode::writeInt32(), and y2debug.

string YStatement::toString ( void  ) const

virtual

Return ASCII represtation of this YCP code.

Returns:

ASCII string representation

Reimplemented from YCode.

Reimplemented in YSSwitch, YSFilename, YSImport, YSInclude, YSTextdomain, YSDo, YSRepeat, YSWhile, YSIf, YSBracket, YSVariable, YSAssign, YSFunction, YSTypedef, YSReturn, YSBlock, YSExpression, YSContinue, and YSBreak.

Referenced by evaluate().

std::ostream & YStatement::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.

Reimplemented in YSSwitch, YSFilename, YSImport, YSInclude, YSTextdomain, YSDo, YSRepeat, YSWhile, YSIf, YSBracket, YSAssign, YSFunction, YSTypedef, YSReturn, YSBlock, YSExpression, YSContinue, and YSBreak.

References m_line.

constTypePtr YStatement::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.

Reimplemented in YSSwitch, YSFilename, YSImport, YSInclude, YSTextdomain, YSDo, YSRepeat, YSWhile, YSIf, YSBracket, YSFunction, YSTypedef, YSReturn, YSBlock, and YSExpression.
