public Instr
clone(CloneInfo
This object manages renaming of variables and labels, handles args and return values.
ii)

Implements abstract org.jruby.ir.instructions.Instr.clone.

Clone the instruction for use in an inlining context (either when a scope is inlined into another scope, or when a block has to be cloned because its associated call belongs to an inlined scope).

Field Detail

coverageback to summary
public boolean coverage

Whether to update coverage data when executing this instruction. Note this is non-final so that `oneshot_lines` mode can disable coverage.

lineNumberback to summary
public final int lineNumber
oneshotback to summary
public final boolean oneshot

Whether to disable coverage after the first execution. This allows lightweight "covered or not" coverage that only updates once per line.

Method Detail

cloneback to summary
public Instr clone(CloneInfo ii)

Implements abstract org.jruby.ir.instructions.Instr.clone.

Doc from org.jruby.ir.instructions.Instr.clone.

Clone the instruction for use in an inlining context (either when a scope is inlined into another scope, or when a block has to be cloned because its associated call belongs to an inlined scope). This might renaming variables and labels to eliminate naming conflicts. The implementation might vary on the cloning mode.

Parameters
ii:CloneInfo

This object manages renaming of variables and labels, handles args and return values.

Returns:Instr

a new instruction that can be used in the target scope.
