Routine details
top source pp_buffered_vector::init
result = pp_buffered_vector::init( [initvec] [, buffersize=buffersize])
Creates a pp_buffered_vector object, with the contents of the given array, or empty if it is not provided. The buffered vector can contain elements of any type. The type is determined by the type of the first element put into it (if not at initialization, at the first append operation).
Parameters
- initvec in optional
An array whose elements are to be placed in the object on creation.
Keywords
- buffersize in optional default=100
Size of the step to use when incrementing the number of elements contained by the object.
Examples
See the example in pp_bufferedvector__define.

top source pp_buffered_vector::append
pp_buffered_vector::append, data
Adds the given data (scalar or array) to the end of the buffered vector, expanding its allocated size if necessary.
Parameters
- data in required
The scalar or array to be put at the end of the buffered vector.
Examples
See the example in pp_bufferedvector__define.

top source pp_buffered_vector::getdata
result = pp_buffered_vector::getdata( [nget] [, all=all] [, count=count])
Retrieves one or more data elements currently stored in the buffered vector.
Return value
If the buffered vector is empty, returns 0, with a count of 0. Otherwise, returns an array with the selected elements from the buffered vector, and the number of elements in count.
Parameters
- nget in optional default=1
The number of elements to retrieve. If positive, the nget first elements are returned. If negative, the last -nget elements are returned. If abs(nget) is larger than the number of elements in the buffered vector, all the elements are returned. The value returned by count must be checked to find out how many elements were actually returned.
Keywords
- all in optional default=0
If set, all the elements stored in the buffered vector are returned.
- count out optional
Returns the number of elements retrieved.
Examples
See the example in pp_bufferedvector__define.

pp_buffered_vector__define
Object to keep an adjustable length vector, using a buffer to decrease the frequency of resizing
It is a simple (without DLM) and relatively efficient implementation of a container similar to a list, intended for light use. For heavy use, it would take a DLM to implement a proper list.
Examples
Make a new empty buffered vector:
a=obj_new('pp_buffered_vector')
print,a->getcount()
;0
a->append,indgen(10)
print,a->getcount()
;10
print,a->getdata(5)
;0 1 2 3 4
rint,a->getdata(-5)
;5 6 7 8 9
print,a->getdata(/all)
;0 1 2 3 4 5 6 7 8 9
print,a->getsize()
;100
print,a->getbuffersize()
;100
obj_destroy,a
