Constructor & Destructor Documentation

xmog_java_double_array::xmog_java_double_array (  jint  size, xmog_localenv *  env = NULL, xmog_flags  = xmog_base::GLOBAL )

Creates a new array instance of a given size. Parameters: size  the newly created array's size. env  the local call environment. May be NULL.

xmog_java_double_array::xmog_java_double_array (  jdouble *  arr, jsize  size, xmog_localenv *  env = NULL, xmog_flags  = xmog_base::GLOBAL )

Creates a new array instance from a native double[]. Parameters: arr  the native double[]. size  the number of elements in the array. env  the local call environment. May be NULL.

Member Function Documentation

static xmog_java_double_array xmog_java_double_array::dyna_cast (  const xmog_java_ref &  _rhs, xmog_localenv *  p_lxenv = NULL, xmog_flags  flags = xmog_base::GLOBAL )  [static]

A framework method which allows a "cast" of the given object to this array type. You use this method in all places where you would use an explicit class cast in Java. It creates a new instance of the correct type and sets the peer object into it if the peer instance is type compatible. If the peer instance is not type compatible, the newly created object will refer to null. Parameters: _rhs  a proxy instance which we wish to "cast" to this type. p_lxenv  the local call environment. The default value is NULL. flags  the flags that allow control over the reference type and other internal matters. The default value is xmog_base::GLOBAL. Returns: an instance of this proxy type that either represents the same Java instance as the argument (if they are type-compatible) or null (if they are not type-compatible).

void xmog_java_double_array::from_native (  jdouble *  src_arr, jint  dest_start, jsize  length, xmog_localenv *  env = NULL )

Copies elements from a native array into the Java array. Parameters: src_arr  a pointer to the native array that provides the elements. dest_start  the index into the Java array to which we start copying. length  the number of elements to copy. env  the local call environment. May be NULL.

jdouble xmog_java_double_array::get (  jint  index, xmog_localenv *  env )  const

Returns the value of an array element. This method provides the same functionality as the subscript operator, but coupled with the ability to pass in a local call environment for a slight edge in performance. Parameters: index  the array element index. env  the local call environment. Default value is NULL.

jdouble xmog_java_double_array::operator[] (  jint  index  )  const

Returns the value of an array element. Parameters: index  the array element index.

xmog_double xmog_java_double_array::operator[] (  jint  index  )

Returns a proxy to a double array element, usable as a lhs-value. Parameters: index  the array element index.

void xmog_java_double_array::set (  jint  index, jdouble  v, xmog_localenv *  env = NULL )

Sets a value into the array's specified element. This method allows direct assignment into an array element while optionally using a provided local call environment. Consequently it will be higher performing than the subscript operator which provides similar functionality in combination with an assignment operation. Parameters: index  the array element index. v  the new value. env  the local call environment. Default value is NULL.

void xmog_java_double_array::to_native (  jdouble *  dest_arr, jint  src_start, jsize  length, xmog_localenv *  env = NULL )

Copies elements from the Java array into a native array. Parameters: dest_arr  a pointer to the native array that will receive the elements. src_start  the index in the Java array from which we start copying. length  the number of elements to copy. env  the local call environment. May be NULL.
