Detailed Description

The stack for executing the Java method.

This structure contains a set of operations specific for the Java stack.

Public Member Functions
	Stack ()

	The destructor.
void	init (void *ptr, int size)
	Initializes the stack of a method.
Value &	pick (int offset=0)
	Returns the reference to the value on the top of the stack.
uint8 &	ref (int offset=0)
	Sets and resets the value to the object reference.
void	push (int size=1)
	Only moves the stack pointer.
void	pop (int size=1)
	Decreases the stack pointer.
void	popClearRef (int size=1)
	Is similar to pop().
void	setLong (int idx, Value2 val)
	Sets the value of an object of the Long or Double type contained in two adjacent stack elements.
Value2	getLong (int idx)
	Returns the Long value located at the depth specified by idx.

Member Function Documentation

void Stack::init	(	void *	ptr,
		int	size
	)

Initializes the stack of a method.

Parameters:

[in]	ptr	- the pointer to the data
[in]	size	- the stack size

Value & Stack::pick

(

int

offset = 0

)

Returns the reference to the value on the top of the stack.

Parameters:

[in]

offset

- the offset value

Returns:

The reference to the value on the top of the stack.

uint8 & Stack::ref

(

int

offset = 0

)

Sets and resets the value to the object reference.

Parameters:

[in]

offset

- the offset value

Returns:

The value to the object reference.

void Stack::push

(

int

size = 1

)

Only moves the stack pointer.

Parameters:

[in]

size

- the size value

void Stack::pop

(

int

size = 1

)

Decreases the stack pointer.

By default, decreases the pointer by one step or as specified in size.

Parameters:

[in]

size

- the required size

void Stack::popClearRef

(

int

size = 1

)

Is similar to pop().

Does the same as pop() and clears the type value associated with every cleared stack element via the ref() function.

Parameters:

[in]

size

- the required size

void Stack::setLong	(	int	idx,
		Value2	val
	)

Sets the value of an object of the Long or Double type contained in two adjacent stack elements.

Parameters:

[in]	idx	- the pointer to the stack depth of the Long value
[in]	val	- the Long value

Value2 Stack::getLong

(

int

idx

)

Returns the Long value located at the depth specified by idx.

Parameters:

[in]

idx

- the value identifier

Returns:

The Long value.

void Stack::clear

(

)

Clears the stack.

int Stack::getStorageSize

(

int

size

)

[static]

Returns the size of the allocated stack area by the elements' size.

Parameters:

[in]

size

- the size in elements

Returns:

The size of the allocated area.

int Stack.getIndex

(

)

Returns the number of elements on the stack.

Returns:

The number of elements on the stack.

Friends And Related Function Documentation

void interp_enumerate_root_set_single_thread_on_stack

(

VM_thread *

)

[friend]

Enumerates references associated with the thread.

Parameters:

[in]

VM_thread

- the pointer to the thread

void interp_ti_enumerate_root_set_single_thread_on_stack	(	jvmtiEnv *	ti_env,
		VM_thread *	thread
	)			[friend]

Enumerates references associated with the thread.

Parameters:

[in]	ti_env	- the pointer to the jvmti environment
[in]	VM_thread	- the pointer to the thread
