start

public final LabelNode start

The start of this subroutine.

localsUsed

public final boolean[] localsUsed

The local variables that are read or written by this subroutine. The i-th element is true if and only if the local variable at index i is read or written by this subroutine.

callers

public final List<JumpInsnNode> callers

构造器详细资料

Subroutine

Subroutine(LabelNode start,
 int maxLocals,
 JumpInsnNode caller)

Constructs a new Subroutine.

参数:

start - the start of this subroutine.

maxLocals - the local variables that are read or written by this subroutine.

caller - a JSR instruction that jump to this subroutine.

Subroutine

Subroutine(Subroutine subroutine)

Constructs a copy of the given Subroutine.

参数:

subroutine - the subroutine to copy.

方法详细资料

merge

public boolean merge(Subroutine subroutine)

Merges the given subroutine into this subroutine. The local variables read or written by the given subroutine are marked as read or written by this one, and the callers of the given subroutine are added as callers of this one (if both have the same start).

参数:

subroutine - another subroutine. This subroutine is left unchanged by this method.

返回:

whether this subroutine has been modified by this method.
