Method Detail

getVariables

NodeList<VariableDeclarator> getVariables()

setVariables

N setVariables(NodeList<VariableDeclarator> variables)

getVariable

default VariableDeclarator getVariable(int i)

setVariable

default N setVariable(int i,
                      VariableDeclarator variableDeclarator)

addVariable

default N addVariable(VariableDeclarator variableDeclarator)

getCommonType

default Type getCommonType()

Returns the type that is shared between all variables. This is a shortcut for when you are certain that all variables share one type. What makes this difficult is arrays, and being able to set the type.
For int a; this is int.
For int a,b,c,d; this is also int.
For int a,b[],c; this is an assertion error since b is an int[], not an int.
For int a,b;, then doing setType(String) on b, this is an assertion error. It is also a situation that you don't really want.

getElementType

default Type getElementType()

Returns the element type.
For int a; this is int.
For int a,b,c,d; this is also int.
For int a,b[],c; this is also int. Note: no mention of b being an array.
For int a,b;, then doing setType(String) on b, then calling getElementType(). This is an assertion error. It is also a situation that you don't really want.

getMaximumCommonType

default Optional<Type> getMaximumCommonType()

Returns the type that maximum shared type between all variables. The minimum common type does never include annotations on the array level.

For int a; this is int.
For int a,b,c,d; this is also int.
For int a,b[],c; this is also int.
For int[] a[][],b[],c[][]; this is int[][].
