Function Documentation

JNIEXPORT void JNICALL Java_se_sics_cooja_corecomm_CLASSNAME_getMemory	(	JNIEnv *	env,
		jobject	obj,
		jint	rel_addr,
		jint	length,
		jbyteArray	mem_arr
	)

Get a segment from the process memory.

Parameters:

start	Start address of segment
length	Size of memory segment

Returns:

Java byte array containing a copy of memory segment.

Fetches a memory segment from the process memory starting at (start), with size (length). This function does not perform ANY error checking, and the process may crash if addresses are not available/readable.

This is a JNI function and should only be called via the responsible Java part (MoteType.java).

JNIEXPORT void JNICALL Java_se_sics_cooja_corecomm_CLASSNAME_init	(	JNIEnv *	env,
		jobject	obj
	)

Initialize a mote by starting processes etc.

This function initializes a mote by starting certain processes and setting up the environment.

This is a JNI function and should only be called via the responsible Java part (MoteType.java).

Definition at line 345 of file contiki-cooja-main.c.

JNIEXPORT void JNICALL Java_se_sics_cooja_corecomm_CLASSNAME_setMemory	(	JNIEnv *	env,
		jobject	obj,
		jint	rel_addr,
		jint	length,
		jbyteArray	mem_arr
	)

Replace a segment of the process memory with given byte array.

Parameters:

start	Start address of segment
length	Size of memory segment
mem_arr	Byte array contaning new memory

Replaces a process memory segment with given byte array. This function does not perform ANY error checking, and the process may crash if addresses are not available/writable.

This is a JNI function and should only be called via the responsible Java part (MoteType.java).

Definition at line 392 of file contiki-cooja-main.c.

JNIEXPORT void JNICALL Java_se_sics_cooja_corecomm_CLASSNAME_setReferenceAddress	(	JNIEnv *	env,
		jobject	obj,
		jint	addr
	)

Set the relative memory address of the reference variable.

Returns:

Relative memory address.

This is a JNI function and should only be called via the responsible Java part (MoteType.java).

Definition at line 474 of file contiki-cooja-main.c.

JNIEXPORT void JNICALL Java_se_sics_cooja_corecomm_CLASSNAME_tick	(	JNIEnv *	env,
		jobject	obj
	)

Let mote execute one "block" of code (tick mote).

Let mote defined by the active contiki processes and current process memory execute some program code. This code must not block or else this function will never return. A typical contiki process will return when it executes PROCESS_WAIT..() statements.

Before the control is left to contiki processes, any messages from the Java part are handled. These may for example be incoming network data. After the contiki processes return control, messages to the Java part are also handled (those which may need special attention).

This is a JNI function and should only be called via the responsible Java part (MoteType.java).
