public class ChainContext
extends java.lang.Object

Provides context that can be used during transformation of chained method calls (e.g. stream calls chain, optional calls chain).

Allows to: 1. register newly allocated variables' names 2. add before / after steps that can be added after transformation is complete 3. create different elements using PsiElementFactory

ChainContext

public ChainContext(PsiElement chainExpression)

ChainContext

public ChainContext(ChainContext parentContext)

Constructs chain context using parent's context chain call, factory and registered names.

Method Detail

registerVarName

public java.lang.String registerVarName(java.util.Collection<java.lang.String> variants)

Choose name from variants for newly allocated variable and register it in context. If all names from variants are already used then variable is named variant$i for i from 1 to Integer.MAX_INTEGER. If no variants are present then variable is named either val or val$i.

Parameters:

variants - possible variable names

Returns:

chosen name

declare

public java.lang.String declare(java.lang.String desiredName,
                                java.lang.String type,
                                java.lang.String initializer)

Add variable declaration to beforeSteps.

Parameters:

desiredName - desired name that is registered in context

type - variable type

initializer - variable initializer

Returns:

addBeforeStep

public void addBeforeStep(java.lang.String beforeStatement)

Add step that will be added before transformation result.

Parameters:

beforeStatement - statement to add

drainBeforeSteps

public java.lang.String drainBeforeSteps()

Get all before steps and remove them from context.

Returns:

before steps

addAfterStep

public void addAfterStep(java.lang.String afterStatement)

Add step that will be added after transformation result.

Parameters:

afterStatement - statement to add

drainAfterSteps

public java.lang.String drainAfterSteps()

Get all after steps and remove them from context.

Returns:

before steps

createExpression

public PsiExpression createExpression(java.lang.String text)

Create expression from text in context of chain call.

createStatement

public PsiStatement createStatement(java.lang.String text)

Create statement from text in context of chain call.

createType
