pygplates.GpmlArray

class pygplates.GpmlArray

Bases: pygplates.PropertyValue

A sequence of property value elements.

GpmlArray behaves like a regular python list in that the following operations are supported:

Operation	Result
for x in s	iterates over the elements x of s
x in s	True if x is an item of s
x not in s	False if x is an item of s
s += t	the GpmlArray instance s is extended by sequence t
s + t	the concatenation of sequences s and t where either, or both, is a GpmlArray
s[i]	the item of s at index i
s[i] = x	replace the item of s at index i with x
del s[i]	remove the item at index i from s
s[i:j]	slice of s from i to j
s[i:j] = t	slice of s from i to j is replaced by the contents of the sequence t (the slice and t can be different lengths)
del s[i:j]	same as s[i:j] = []
s[i:j:k]	slice of s from i to j with step k
del s[i:j:k]	removes the elements of s[i:j:k] from the list
s[i:j:k] = t	the elements of s[i:j:k] are replaced by those of t (the slice and t must be the same length if k != 1)
len(s)	length of s
s.append(x)	add element x to the end of s
s.extend(t)	add the elements in sequence t to the end of s
s.insert(i,x)	insert element x at index i in s
s.pop([i])	removes the element at index i in s and returns it (defaults to last element)
s.remove(x)	removes the first element in s that equals x (raises ValueError if not found)
s.count(x)	number of occurrences of x in s
s.index(x[,i[,j]])	smallest k such that s[k] == x and i <= k < j (raises ValueError if not found)
s.reverse()	reverses the items of s in place
s.sort(key[,reverse])	sort the items of s in place (note that key is not optional and, like python 3.0, we removed cmp)

All elements should have the same type (such as GmlTimePeriod).

__init__(elements)

Create an array from a sequence of property value elements.

Parameters

elements (Any sequence such as a list or a tuple) – A sequence of PropertyValue elements.

Raises

RuntimeError if sequence is empty

Note that all elements should have the same type (such as GmlTimePeriod).

Note

The sequence of elements must not be empty (for technical implementation reasons), otherwise a RuntimeError exception will be thrown.

array = pygplates.GpmlArray(elements)

Methods

__init__(elements)	Create an array from a sequence of property value elements.
accept_visitor(visitor)	Accept a property value visitor so that it can visit this property value.
append(x)	Add element x to the end.
clone()	Create a duplicate of this property value (derived) instance, including a recursive copy of any nested property values that this instance might contain.
count(x)	Number of occurrences of x.
extend(t)	Add the elements in sequence t to the end.
get_geometry()	Extracts the geometry if this property value contains a geometry.
get_value([time=0])	Extracts the value, of this possibly time-dependent property value, at the reconstruction time.
index(x[,i[,j]])	Smallest k such that the k th element equals x and i <= k < j (raises ValueError if not found).
insert(i, x)	Insert element x at index i.
pop([i])	Removes the element at index i and returns it (defaults to last element).
remove(x)	Removes the first element that equals x (raises ValueError if not found).
reverse()	Reverses the items in place.
sort(key[,reverse])	Sort the items in place (note that key is not optional and, like python 3.0, we removed cmp).

append(x)

Add element x to the end.

count(x)

Number of occurrences of x.

extend(t)

Add the elements in sequence t to the end.

index(x[, i[, j]])

Smallest k such that the k th element equals x and i <= k < j (raises ValueError if not found).

insert(i, x)

Insert element x at index i.

pop([i])

Removes the element at index i and returns it (defaults to last element).

remove(x)

Removes the first element that equals x (raises ValueError if not found).

reverse()

Reverses the items in place.

sort(key[, reverse])

Sort the items in place (note that key is not optional and, like python 3.0, we removed cmp).
