EclipseLink ASM 9.6.0 · org.eclipse.persistence.internal.libraries.asm.tree.FrameNode

A node that represents a stack map frame. These nodes are pseudo instruction nodes in order to be inserted in an instruction list. In fact these nodes must(*) be inserted just before any instruction node i that follows an unconditionnal branch instruction such as GOTO or THROW, that is the target of a jump instruction, or that starts an exception handler block. The stack map frame types must describe the values of the local variables and of the operand stack elements just before i is executed.

(*) this is mandatory only for classes whose version is greater than or equal to Opcodes#V1_6.
