Detailed Description

Expandable array.

Member Function Documentation

ytStrArray_add()

void ytStrArray_add	(	ytStrArray *	this,
		char *	value
	)

Adds a value.

Parameters

this
value

ytStrArray_arrayDelete()

void ytStrArray_arrayDelete	(	ytStrArray *	this,
		size_t	size
	)

Deletes the array of ytStrArray instances.

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

Parameters

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

ytStrArray_arrayNew()

ytStrArray * ytStrArray_arrayNew

(

size_t

size

)

Creates the array of ytStrArray instances.

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

;
 
ytStrArray * ar = ytStrArray_arrayNew(size);
 
 
ytStrArray_add(ar + i, value);
 
...

Use ytStrArray_arrayDelete() to delete the allocated instances.

Parameters

size	the number of instances to allocate.

ytStrArray_arrayDelete()

ytStrArray_buffSize()

size_t ytStrArray_buffSize

(

const ytStrArray *

this

)

Returns the current buffer size allocated.

Parameters

this	pointer to the ytStrArray instance.

Returns

the size of allocated buffer in bytes.

ytStrArray_clear()

void ytStrArray_clear

(

ytStrArray *

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.

ytStrArray_copy()

void ytStrArray_copy	(	ytStrArray *	this,
		const ytStrArray *	src
	)

Copies values in another array into this.

Parameters

this
src

ytStrArray_copyArray()

void ytStrArray_copyArray	(	ytStrArray *	this,
		size_t	index,
		const char **	array,
		size_t	size
	)

Copies values in an array into this array.

Parameters

this
index
array
size

ytStrArray_find()

size_t ytStrArray_find	(	const ytStrArray *	this,
		const char *	v
	)

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

Parameters

this
v	Value to find.

Returns

index, or ytStrArray_ERROR_VALUE if not found.

ytStrArray_insert()

void ytStrArray_insert	(	ytStrArray *	this,
		size_t	index,
		char *	value
	)

Inserts a value at the specified position.

Parameters

this
index
value

ytStrArray_memSize()

size_t ytStrArray_memSize

(

const ytStrArray *

this

)

Returns the size of memory where the specified instance occupies.

Parameters

this	pointer to the ytStrArray instance.

Returns

the size of occupied memory size by the instance.

ytStrArray_MPI_Bcast()

void ytStrArray_MPI_Bcast	(	ytStrArray **	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).

ytStrArray_new()

ytStrArray * ytStrArray_new

(

)

Creates a new ytStrArray instance.

Returns

pointer to the newly created ytStrArray instance.

ytStrArray_pop()

char * ytStrArray_pop

(

ytStrArray *

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.

ytStrArray_print()

void ytStrArray_print	(	const ytStrArray *	this,
		FILE *	fp,
		char *	delim
	)

Prints the elements in the array.

Parameters

this
fp	FILE pointer to output.
delim	delimitor

ytStrArray_remove()

char * ytStrArray_remove	(	ytStrArray *	this,
		size_t	index
	)

\breif Removes the value at the specified position.

Returns

element to be deleted from the array.

ytStrArray_set()

void ytStrArray_set	(	ytStrArray *	this,
		size_t	index,
		char *	value
	)

Sets a value at the specified position.

Parameters

this
index
value

ytStrArray_setBuffSize()

ytStrArray * ytStrArray_setBuffSize	(	ytStrArray *	this,
		size_t	new_size
	)

Changes the size of buffer.

Parameters

this
new_size

Returns

this, or NULL if failed.

Go to Top

ytStrArray_setSize()

void ytStrArray_setSize	(	ytStrArray *	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	===================================================

ytStrArray_sort()

void ytStrArray_sort

(

ytStrArray *

this

)

Sorts the elements in ascending order.

Parameters

this
