- Method Detail
  - getExplicitParameterTypes
```
@Nullable List<JTypeMirror> getExplicitParameterTypes()
```
    Returns the types of the explicit parameters. If the lambda is implicitly typed, then returns null.
    Note that a degenerate case of explicitly typed lambda expression is a lambda with zero formal parameters.
  - isExplicitlyTyped
```
default boolean isExplicitlyTyped()
```
    See getExplicitParameterTypes().
  - getParamCount
```
int getParamCount()
```
    Return the number of parameters of the lambda, regardless of whether it's explicitly typed or not.
  - getResultExpressions
```
Iterable<ExprMirror> getResultExpressions()
```
    Returns all the expressions that appear in return statements within the lambda. If this is an expression-bodied lambda, returns the expression.
  - isValueCompatible
```
boolean isValueCompatible()
```
    Returns true if the body is value-compatible (JLS§15.27.2).
    A block lambda body is value-compatible if it cannot complete normally (§14.21) and every return statement in the block has the form return Expression;.
  - isVoidCompatible
```
boolean isVoidCompatible()
```
    Returns true if the body is void-compatible (JLS§15.27.2).
    A block lambda body is void-compatible if every return statement in the block has the form return;.
  - updateTypingContext
```
void updateTypingContext(JMethodSig groundFun)
```
