◆ checkExtern()

void BFN::CheckExternInvocationCommon::checkExtern	(	const P4::ExternMethod *	extMethod,
		const IR::MethodCallExpression *	expr )

overrideprotectedvirtual

Method for checking constraints of extern method given by parameters.

If there are no constraints for extern methods, inheriting class does not need to implement this method.

Parameters

extMethod	Pointer to object representing extern method.
expr	Pointer to method call expression.

Reimplemented from P4::CheckExternInvocationCommon.

◆ getBlockName()

cstring BFN::CheckExternInvocationCommon::getBlockName ( int bit )

inlineoverrideprotectedvirtual

Get the name of the block which is represented in bit vector (bitvec) by bit with index given by 'bit' parameter.

Parameters

bit	Index of bit which represents the block in bit vector.

Returns: cstring Name of the block represented by index with 'bit' parameter value.

Implements P4::CheckExternInvocationCommon.
