Description
All generated SOAP-Encoded arrays are derived from rwsf::ArrayHandle<T> instantiated on the type of element contained in the array.
rwsf::ArrayHandle implements the handle/body idiom in which rwsf::ArrayBody is the body. The handle passes all methods to the body, which contains an instance of rwsf::SoapArray, the class that contains all the actual container functionality and to which the array body passes all its methods.
For more information on SOAP-Encoded arrays, see Section A.5.1, "SOAP-Encoded Arrays," in the HydraExpress Web Service Development Guide
Note: For information on the parent class rwsf::XmlOlHandle, see its entry in the HydraExpress XML Binding Reference Guide.
NOTE -- Handle methods that just call the corresponding method on the body are described only in the body class. For instance, if the handle class includes a method invoke() that calls the body's corresponding method doInvoke(), that method is documented only in the body class.
Example
In this example, genArray is a SOAP array containing doubles, derived from rwsf::ArrayHandle.
//
// genArrayExample.cpp
//
#include "genArray.h"
#include <iostream>
using std::cout;
using std::endl;
int main() {
genArray array;
array.insert(22.0);
array.insert(5.3);
array.insert(-102.5);
array.insert(15.0);
array.insert(5.3);
// Prints "5"
cout << array.entries() << " entries\n" << endl;
for (genArray::iterator it = array.begin();
it != array.end(); it++)
cout << *it << endl;
return 0;
}
Program Output:
5 entries 22 5.3 -102.5 15 5.3
Public Typedefs
typedef typename rwsf::ArrayBody<T> body_type; typedef typename body_type::iterator
iterator; typedef typename body_type::const_iterator const_iterator; typedef typename body_type::size_type size_type; typedef typename body_type::value_type value_type; typedef typename body_type::reference reference; typedef typename body_type::const_reference const_reference;
Public Constructors
ArrayHandle<T>(ArrayBody<T>* body)
Constructs a new handle attached to the body body.
ArrayHandle<T>(const ArrayHandle<T>& other)
Copy constructor. Constructs a new handle from handle other.
ArrayHandle<T>(const rwsf::SoapArray<T>& body)
Constructs a new handle using the rwsf::SoapArray as the basis for the new body.
Iterators
iterator begin(); const_iterator begin() const;
Returns an iterator positioned at the first element of the body.
iterator end(); const_iterator end() const;
Returns a past-the-end valued iterator of the body.
iterator insert(iterator it, const_reference key);
Adds the item key before position it in the array. The return value points to the position it.
iterator insert(const_reference key);
Adds the item key to the end of the collection.
Public Member Operators
reference operator()(size_type idx); const_reference operator() (size_type idx) const;
Returns a reference to the idxth element of the body. Index idx should be between 0 and one less then the number of entries, otherwise the results are undefined. No bounds checking is performed.
reference operator[](size_type idx); const_reference operator[](size_type idx) const;
Returns a reference to the idxth element of the body. Index idx must be between 0 and one less then the number of entries in self, otherwise the function throws an exception of type rwsf::OutOfBoundsException.
Public Member Functions
void append(const_reference item);
Adds item to the end of the collection body.
reference at(size_type idx); const_reference at(size_type idx) const;
Returns a reference to the idxth element of the body. Index idx must be between 0 and one less then the number of entries in self, otherwise the function throws an exception of type rwsf::OutOfBoundsException.
reference back(); const_reference back() const;
Returns a reference to the last element.
void clear();
Clears the collection by removing all items from the body. Each item will have its destructor called.
bool contains(const_reference key) const;
Returns true if there exists an element t in self such that the expression(t == key) is true, otherwise returns false.
bool empty() const;
Returns true if the size is zero.
size_type entries() const;
Returns the number of elements in the body.
bool find(const_reference key, value_type& val) const;
If there exists an element t in self such that the expression (t == key) is true, assigns t to val and returns true. Otherwise, returns false and leaves the value of val unchanged.
reference first(); const_reference first() const;
Returns a reference to the first element of the body.
std::vector<size_t>& getDimensions() const std::vector<size_t>& getDimensions() const
Returns a vector containing the size of each dimension in the array. If the array is int[2,3,4], then the returned vector contains 2, 3 and 4 in that order. Any dimension without a size is set to 0. For example, a one-dimension array returns a vector with a single element whose value is the upper bound of the array or 0 if there is no upper bound (defined as int[]).
size_type index(const_reference key) const;
Returns the position of the first item t in the body, such that (t == key), or returns rwsf_NPOS if no such item exists.
void insertAt(size_type index, const_reference item);
Inserts item in front of the item at position index in self. This position must be between 0 and the number of entries in the collection, otherwise the function throws an exception of type rwsf::OutOfBoundsException.
bool isEmpty() const;
Returns true if there are no items in the collection, false otherwise.
reference last(); const_reference last() const;
Returns a reference to the last item in the collection.
size_type length() const;
Returns the number of elements in the body.
size_type occurrencesOf(const_reference key) const;
Returns the number of elements t in self such that the expression (t == key) is true.
void parseDimensions(const std::string& arrayType) Parses the dimension string in the XML SOAP Array definition and sets the array dimensions in "this". void prepend(const_reference item);
Adds the item a to the beginning of the collection.
void push_back(const_reference item);
Inserts a copy of item to the end of the body.
bool remove(const_reference key);
Removes the first element t in self such that the expression (t == key) is true and returns true. Returns false if there is no such element.
size_type removeAll(const_reference key);
Removes all elements t in self such that the expression (t == key) is true. Returns the number of items removed.
value_type removeAt(size_type index);
Removes and returns the item at position index in self. This position must be between 0 and one less then the number of entries in the collection, otherwise the function throws an exception of type rwsf::OutOfBoundsException.
value_type removeFirst();
Removes and returns the first item in the collection.
value_type removeLast();
Removes and returns the last item in the collection.
size_type replaceAll(const_reference oldVal, const_reference newVal);
Replaces all elements t in self such that the expression (t == oldVal) is true with newVal. Returns the number of items replaced.
void resize(size_t n);
Modify the capacity of the vector to be at least as large as n. The function has no effect if the capacity is already as large as n.
size_type size() const
Returns the number of elements in the body.
Protected Member Functions
body_type & body() const body_type& body() const
Returns the array, a rwsf::ArrayBody.
