Detailed Description

Expandable array.

Member Function Documentation

ytIntArray_add()

void ytIntArray_add	(	ytIntArray *	this,
		int	value
	)

Adds a value.

Parameters

this
value

ytIntArray_arrayDelete()

void ytIntArray_arrayDelete	(	ytIntArray *	this,
		size_t	size
	)

Deletes the array of ytIntArray instances.

This deletes the array of the instances allocated by ytIntArray_arrayNew(). The users have to specify the same number to the size parameter as specified to ytIntArray_arrayNew().

Parameters

this	pointer returned by ytIntArray_arrayNew().
size	the size of the array.

ytIntArray_arrayNew()

ytIntArray * ytIntArray_arrayNew

(

size_t

size

)

Creates the array of ytIntArray instances.

The i -th istance can be accecced by p + i where p is the pointer returned by this. For example:

;
 
ytIntArray * ar = ytIntArray_arrayNew(size);
 
 
ytIntArray_add(ar + i, value);
 
...

Use ytIntArray_arrayDelete() to delete the allocated instances.

Parameters

size	the number of instances to allocate.

ytIntArray_arrayDelete()

ytIntArray_buffSize()

size_t ytIntArray_buffSize

(

const ytIntArray *

this

)

Returns the current buffer size allocated.

Parameters

this	pointer to the ytIntArray instance.

Returns

the size of allocated buffer in bytes.

ytIntArray_clear()

void ytIntArray_clear

(

ytIntArray *

this

)

Removes all the elements in the array.

This does not remove the element but set the number of elements in the array to be zero. No memory de-allocation occurs.

ytIntArray_copy()

void ytIntArray_copy	(	ytIntArray *	this,
		const ytIntArray *	src
	)

Copies values in another array into this.

Parameters

this
src

ytIntArray_copyArray()

void ytIntArray_copyArray	(	ytIntArray *	this,
		size_t	index,
		const int *	array,
		size_t	size
	)

Copies values in an array into this array.

Parameters

this
index
array
size

ytIntArray_find()

size_t ytIntArray_find	(	const ytIntArray *	this,
		const int	v
	)

Returns the index of the value identical to the given one.

Parameters

this
v	Value to find.

Returns

index, or ytIntArray_ERROR_VALUE if not found.

ytIntArray_insert()

void ytIntArray_insert	(	ytIntArray *	this,
		size_t	index,
		int	value
	)

Inserts a value at the specified position.

Parameters

this
index
value

ytIntArray_memSize()

size_t ytIntArray_memSize

(

const ytIntArray *

this

)

Returns the size of memory where the specified instance occupies.

Parameters

this	pointer to the ytIntArray instance.

Returns

the size of occupied memory size by the instance.

ytIntArray_MPI_Bcast()

void ytIntArray_MPI_Bcast	(	ytIntArray **	pObject,
		int	root,
		MPI_Comm	comm
	)

Broadcasts the array with MPI.

This is available only for the MPI-enabled ytLib.

This allocates working memory whose size is the same as the total memory required for storing all the elements in the array.

This calls MPI_Ibcast() three times internally.

Parameters

pObject

pointer to the array instance. in receiving ranks, the new instance is generated and set to the original pointer (*pObject).

ytIntArray_new()

ytIntArray * ytIntArray_new

(

)

Creates a new ytIntArray instance.

Returns

pointer to the newly created ytIntArray instance.

ytIntArray_pop()

int ytIntArray_pop

(

ytIntArray *

this

)

Returns the last element.

The last element is returned and removed from the array.

Parameters

this

Returns

value at the end of the array.

ytIntArray_print()

void ytIntArray_print	(	const ytIntArray *	this,
		FILE *	fp,
		char *	delim
	)

Prints the elements in the array.

Parameters

this
fp	FILE pointer to output.
delim	delimitor

ytIntArray_remove()

int ytIntArray_remove	(	ytIntArray *	this,
		size_t	index
	)

\breif Removes the value at the specified position.

Returns

element to be deleted from the array.

ytIntArray_set()

void ytIntArray_set	(	ytIntArray *	this,
		size_t	index,
		int	value
	)

Sets a value at the specified position.

Parameters

this
index
value

ytIntArray_setBuffSize()

ytIntArray * ytIntArray_setBuffSize	(	ytIntArray *	this,
		size_t	new_size
	)

Changes the size of buffer.

Parameters

this
new_size

Returns

this, or NULL if failed.

ytIntArray_setSize()

void ytIntArray_setSize	(	ytIntArray *	this,
		size_t	size
	)

Changes the size of the array.

If the specified size is larger than the current size, new elements are not initialized.

If the specified size is less than the current size, this does not free the allocated memory. Instead, this simply changes the current size without changing any elements in the array.

Parameters

this
size	===================================================

ytIntArray_sort()

void ytIntArray_sort

(

ytIntArray *

this

)

Sorts the elements in ascending order.

Parameters

this
