Implements Tracer.

Definition at line 62 of file StoreTracer.cc.

References trace().

void StoreTracer::dequeue	(	const DTN::Bundle &	b,
		const DTN::Node *	n

Parameters:

	b	The bundle being dequeued
	n	The node at which the bundle is dequeued

Implements Tracer.

Definition at line 69 of file StoreTracer.cc.

References trace().

void StoreTracer::send	(	const DTN::Bundle &	b,
		const DTN::Node *	n
	)			[virtual]

Create a trace entry for a bundle send.

Parameters:

	b	The bundle being sent
	n	The node from which the bundle is sent

Implements Tracer.

Definition at line 76 of file StoreTracer.cc.

void StoreTracer::receive	(	const DTN::Bundle &	b,
		const DTN::Node *	n
	)			[virtual]

Create a trace entry for a received bundle.

Parameters:

	b	The bundle being received
	n	The node at which the bundle is received

Implements Tracer.

Definition at line 81 of file StoreTracer.cc.

void StoreTracer::drop	(	const DTN::Bundle &	b,
		const DTN::DropCause &	c,
		const DTN::Node *	n
	)			[virtual]

Create a trace entry for a dropped bundle.

Parameters:

	b	The bundle being dropped
	c	The reason for dropping the bundle
	n	The node at which the drop occurs

Implements Tracer.

Definition at line 86 of file StoreTracer.cc.

void StoreTracer::trace

(

const DTN::Node &

std::string StoreTracer::stringify

(

const DTN::ByteString &

b

)

const [protected]

Create a printable version of a ByteString.

If b is comprised entirely of printable ASCII characters, we convert directly. If not, we represent it as a hex string of the form "0x...".

Parameters:

b

The string of bytes to be printed

Returns:

the printable form of b
