◆ xmog_java_float_array() [1/2]

xmog_java_float_array::xmog_java_float_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_float_array() [2/2]

xmog_java_float_array::xmog_java_float_array	(	jfloat *	arr,
		jsize	size,
		xmog_localenv *	env = `NULL`,
		xmog_flags	= `xmog_base::GLOBAL`
	)

Creates a new array instance from a native float[].

Parameters

arr	the native `float`[].
size	the number of elements in the array.
env	the local call environment. May be `NULL`.

Member Function Documentation

◆ dyna_cast()

static xmog_java_float_array xmog_java_float_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).

◆ from_native()

void xmog_java_float_array::from_native	(	jfloat *	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`.

◆ get()

jfloat xmog_java_float_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`.

◆ operator[]() [1/2]

xmog_float xmog_java_float_array::operator[] ( jint index )

Returns a proxy to a float array element, usable as a lhs-value.

Parameters

index the array element index.

◆ operator[]() [2/2]

jfloat xmog_java_float_array::operator[] ( jint index ) const

Returns the value of an array element.

Parameters

index the array element index.

◆ set()

void xmog_java_float_array::set	(	jint	index,
		jfloat	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`.

◆ to_native()

void xmog_java_float_array::to_native	(	jfloat *	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`.
