Detailed Description

Value containing a signed, relative address.

When asking for unsigned integer value, exact address is returned; when printing or getting signed value, relative address is used.

Constructor & Destructor Documentation

RelAddressValue() [1/2]

RelAddressValue::RelAddressValue ( const RelAddressValue &  value )

delete

Copy constructor, disabled.

Parameters

[in]

value

The value to copy.

RelAddressValue() [2/2]

RelAddressValue::RelAddressValue	(	uint32	base_addr,
		int32	offset
	)

Constructor.

Parameters

[in]	base_addr	The base address for the offset.
[in]	offset	The relative offset to the base address.

Member Function Documentation

Dup()

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

overridevirtual

Duplicates the value.

Parameters

[out]

output

The stream to output any necessary assignment.

Returns

A Value corresponding to a duplicate of the value.

Reimplemented from IntValue.

GetUnsigned()

uint32 RelAddressValue::GetUnsigned ( )

overridevirtual

Retrieves the exact address.

Returns

The exact address.

Exceptions

WrongTypeException

if the value is not an integer.

Reimplemented from IntValue.

IsAddress()

bool RelAddressValue::IsAddress ( )

overridevirtual

Return whether or not the Value is an address.

Returns

True.

Reimplemented from Value.

operator=()

RelAddressValue & RelAddressValue::operator= ( const RelAddressValue &  value )

delete

Copy constructor, disabled.

Parameters

[in]

value

The value to copy.

Print()

std::ostream & RelAddressValue::Print ( std::ostream &  output ) const

overridevirtual

Print the relative address to a stream.

Parameters

[out]

output

The stream to write to.

Returns

The stream used for output.

Reimplemented from IntValue.

Member Data Documentation

base_addr_

const uint32 RelAddressValue::base_addr_

protected

The base address for the offset.
