Detailed Description

Class representing a value (stack entry, parameter, etc.)

Constructor & Destructor Documentation

~Value()

Value::~Value ( )

virtual

Destructor.

Member Function Documentation

Dup()

ValuePtr Value::Dup ( std::ostream &  output )

virtual

Duplicates a value.

Parameters

[out]

output

The stream to output any necessary assignment.

Returns

A Value corresponding to a duplicate of this entry.

Reimplemented in IntValue, AddressValue, RelAddressValue, and DupValue.

GetPrecedence()

int Value::GetPrecedence ( ) const

virtual

Operator precedence for this value.

Lower values bind stronger, i.e. they are resolved earlier. If an operand has a higher precedence value than the operator, parentheses are not required for that operand.

Returns

The order of precedence.

Reimplemented in BinaryOpValue, and UnaryOpValue.

GetSigned()

int32 Value::GetSigned ( )

virtual

Retrieves a signed integer representing the value, if possible.

Returns

A signed integer representing the value, if possible.

Exceptions

WrongTypeException

if the value is not an integer.

Reimplemented in IntValue, and AddressValue.

GetString()

std::string Value::GetString ( ) const

virtual

Retrieves the string representation of the value.

Returns

The string representation of the value.

GetUnsigned()

uint32 Value::GetUnsigned ( )

virtual

Retrieves an unsigned integer representing the value, if possible.

Returns

An unsigned integer representing the value, if possible.

Exceptions

WrongTypeException

if the value is not an integer.

Reimplemented in IntValue, and RelAddressValue.

IsAddress()

bool Value::IsAddress ( )

virtual

Return whether or not the Value is an address.

Returns

True if the Value is an address, otherwise false.

Reimplemented in AddressValue, and RelAddressValue.

IsInteger()

bool Value::IsInteger ( )

virtual

Return whether or not the Value is an integer.

Returns

True if the Value is an integer, otherwise false.

Reimplemented in IntValue.

IsSignedValue()

bool Value::IsSignedValue ( )

virtual

Returns whether or not any stored integer value is signed.

Returns

True if the integer value is signed, false if it is not.

Exceptions

WrongTypeException

if the value is not an integer.

Reimplemented in IntValue.

Negate()

ValuePtr Value::Negate ( )

virtual

Negates a value.

Returns

The current Value, negated.

Exceptions

WrongTypeException

if negation is not possible.

Reimplemented in BinaryOpValue, and NegatedValue.

Print()

virtual std::ostream & Value::Print ( std::ostream &  output ) const

pure virtual

Print the value to a stream.

Parameters

[out]

output

The stream to write to.

Returns

The stream used for output.

Implemented in IntValue, AddressValue, RelAddressValue, DupValue, StringValue, UnquotedStringValue, VarValue, ArrayValue, BinaryOpValue, UnaryOpValue, and CallValue.

Friends And Related Function Documentation

operator<<

std::ostream & operator<< ( std::ostream &  output, Value *  value  )

friend

Output a value to a stream.

Parameters

[out]	output	The stream to output to.
[in]	value	Reference counted pointer to the value to output.

Returns

The stream used for output.
