dload_n : retrieve double from local variables <n> and <n> + 1 : index :

Description

Retrieves the double-precision float stored in local variables <n> and <n> + 1 and pushes it onto the operand stack. Both <n> and <n> + 1 must be valid local variable numbers in the current frame, and together they must be holding a double.

See the description of dload for more information on how doubles are retrieved from local variables.

'dload_n' is functionally equivalent to 'dload <n>', although it is typically more efficient and also takes fewer bytes in the bytecode.

Example

dload_0         ; push double in local variables 0 and 1 onto stack
dload_1         ; push double in local variables 1 and 2 onto stack
dload_2         ; push double in local variables 2 and 3 onto stack
dload_3         ; push double in local variables 3 and 4 onto stack
