Protected Attributes
std::vector< IndexExpression >	indexConditions
	Each element is an API name paired with a match rule.
const IR::Expression *	initialValue
	A new IndexMap always requires an initial value. This can be a constant or taint.

Detailed Description

Member Function Documentation

getEvaluatedInitialValue()

const IR::Constant * P4::P4Tools::P4Testgen::Bmv2::IndexMap::getEvaluatedInitialValue ( ) const

nodiscard

Returns

the evaluated register value. This means it must be a constant. The function will throw a bug if this is not the case.

getInitialValue()

const IR::Expression * P4::P4Tools::P4Testgen::Bmv2::IndexMap::getInitialValue ( ) const

nodiscard

Returns

the value with which this register has been initialized.

getValueAtIndex()

const IR::Expression * P4::P4Tools::P4Testgen::Bmv2::IndexMap::getValueAtIndex ( const IR::Expression * index ) const

nodiscard

Returns

the current value of this register after writes have been performed according to a provided index.

writeToIndex()

void P4::P4Tools::P4Testgen::Bmv2::IndexMap::writeToIndex	(	const IR::Expression *	index,
		const IR::Expression *	value )

Write.

Parameters

value	to
index.
