public void setTarget(MethodHandle target) Overrides java.lang.invoke.MutableCallSite.setTarget. Doc from java.lang.invoke.MutableCallSite.setTarget. Updates the target method of this call site, as a normal variable. The type of the new target must agree with the type of the old target. The interactions with memory are the same as of a write to an ordinary variable, such as an array element or a non-volatile, non-final field. In particular, unrelated threads may fail to see the updated target until they perform a read from memory. Stronger guarantees can be created by putting appropriate operations into the bootstrap method and/or the target methods used at any given call site. Parameters target:MethodHandle the new target

public void setTarget(MethodHandle target)

Overrides java.lang.invoke.MutableCallSite.setTarget.

Doc from java.lang.invoke.MutableCallSite.setTarget.

Updates the target method of this call site, as a normal variable. The type of the new target must agree with the type of the old target.

The interactions with memory are the same as of a write to an ordinary variable, such as an array element or a non-volatile, non-final field.

In particular, unrelated threads may fail to see the updated target until they perform a read from memory. Stronger guarantees can be created by putting appropriate operations into the bootstrap method and/or the target methods used at any given call site.

Parameters

target:MethodHandle: the new target
