question: 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 . concode_field_sep SpelNodeImpl parent concode_elem_sep SpelNodeImpl[] NO_CHILDREN concode_elem_sep SpelNodeImpl[] children concode_elem_sep int pos concode_elem_sep String exitTypeDescriptor concode_field_sep SpelNodeImpl getPreviousChild concode_elem_sep void generateCodeForArgument concode_elem_sep TypedValue getValueInternal concode_elem_sep Class<?> getObjectClass concode_elem_sep void generateCode concode_elem_sep SpelNode getChild concode_elem_sep int getEndPosition concode_elem_sep boolean isWritable concode_elem_sep int getChildCount concode_elem_sep int getStartPosition concode_elem_sep Object getValue concode_elem_sep T getValue concode_elem_sep ValueRef getValueRef concode_elem_sep String getExitDescriptor concode_elem_sep void setValue concode_elem_sep TypedValue getTypedValue concode_elem_sep void generateCodeForArguments concode_elem_sep boolean nextChildIs
