Method Detail
isCompilable
public boolean isCompilable()
Check whether a node can be compiled to bytecode. The reasoning in each node may
be different but will typically involve checking whether the exit type descriptor
of the node is known and any relevant child nodes are compilable.
Overrides:
isCompilable
in class SpelNodeImpl
Returns:
true
if this node can be compiled to bytecode
generateCode
public void generateCode(MethodVisitor mv,
CodeFlow cf)
Generate the bytecode for this node into the supplied visitor. Context info about
the current expression being compiled is available in the codeflow object. For
example it will include information about the type of the object currently
on the stack.
Overrides:
generateCode
in class SpelNodeImpl
Parameters:
mv
- the ASM MethodVisitor into which code should be generated
cf
- a context object with info about what is on the stack
