Method Details

getType

@Nullable
@Nullable JavaType getType()

withType

<T extends J> T withType(@Nullable
 @Nullable JavaType type)

getSideEffects

default List<J> getSideEffects()

Returns:

A list of the side effects emitted by the statement, if the statement was decomposed. So for a binary operation, there are up to two potential side effects (the left and right side) and as few as zero if both sides of the expression are something like constants or variable references.

unwrap

default Expression unwrap()

If this expression is a J.Parentheses return the expression inside the parentheses this. Otherwise, return this. This operation is performed recursively to return the first non-parenthetical expression.

Returns:

The expression as if all surround parentheses were removed. Never a J.Parentheses instance.

unwrap

@Nullable
static @Nullable Expression unwrap(@Nullable
 @Nullable Expression expr)

getCoordinates

CoordinateBuilder.Expression getCoordinates()
