Detailed Description

function declaration (m_body == 0) or definition (m_body != 0) it's anonymouse here ! The code() member of the corresponding SymbolEntry points to YFunction.

string YFunction::toString

(

void

)

const [virtual]

Return ASCII represtation of this YCP code.

Returns:

ASCII string representation

Reimplemented from YCode.

std::ostream & YFunction::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_declaration, YCode::toStream(), Bytecode::writeBool(), and y2debug.

std::ostream & YFunction::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 m_declaration, m_definition, Xmlcode::popNamespace(), Xmlcode::pushNamespace(), and Xmlcode::spaces().

YCPValue YFunction::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.

References toString(), and y2debug.

constTypePtr YFunction::type

(

)

const [virtual]

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 parameter(), parameterCount(), and Type::Unspec.
