StackFrame Command Set

Returns the value of one or more local variables in a given frame. Each variable must be visible at the current frame code index. Even if local variable information is not available, values can be retrieved if the front-end is able to determine the correct local variable index. (Typically, this index can be determined for method arguments from the method signature without access to the local variable table information.)

Out Data

TABLE 38 – Structure of Out Data for GetValues Command
`threadID`	threadObject	The frame's thread.
`frameID`	frame	The frame ID.
`int`	slots	The number of values to get.
Repeated slots times:
`int`	slot	The local variable's index in the frame.
`byte`	sigbyte	A tag identifying the type of the variable

Reply Data

TABLE 39 – Structure of Reply Data for GetValues Command
`int`	values	The number of values retrieved.
Repeated values times:
`value`	slotValue	The value of the local variable.

Sets the value of one or more local variables. Each variable must be visible at the current frame code index. For primitive values, the value's type must match the variable's type exactly. For object values, there must be a widening reference conversion from the value's type to the variable's type and the variable's type must be loaded.

Even if local variable information is not available, values can be set, if the front-end is able to determine the correct local variable index. (Typically, this index can be determined for method arguments from the method signature without access to the local variable table information.)

Out Data

TABLE 40 – Structure of Out Data for SetValues Command
`threadID`	threadObject	The frame's thread.
`frameID`	frame	The frame ID.
`int`	slotValues	The number of values to set.
Repeated slotValues times:
`int`	slot	The slot ID.
`value`	slotValue	The value to set.
