- com.google.template.soy.shared.internal.CodeBuilder<E>

Direct Known Subclasses:

IncrementalDomCodeBuilder
```
public abstract class CodeBuilder<E extends TargetExpr>
extends Object
```
A class for building code.
All implementations share indenting behavior and output variable behavior, while implementing their own idiosyncrasies for creating and modifying output variables.

Method Summary

Methods
Modifier and Type	Method and Description
`abstract void`	`addToOutputVar(List<? extends E> targetExprs)` Appends a line/statement with the concatenation of the given target expressions saved to the current output variable.
`CodeBuilder<E>`	`append(String... codeFragments)` Appends one or more strings to the generated code.
`CodeBuilder<E>`	`appendLine(String... codeFragments)` Appends the current indent, then the given strings, then a newline.
`CodeBuilder<E>`	`appendLineEnd(String... codeFragments)` Appends the given strings, then a newline.
`CodeBuilder<E>`	`appendLineStart(String... codeFragments)` Appends the current indent, then the given strings.
`CodeBuilder<E>`	`appendOutputVarName()` Appends the name of the current output variable.
`void`	`decreaseIndent()` Decreases the current indent.
`void`	`decreaseIndentTwice()` Decreases the current indent twice.
`String`	`getCode()`
`protected boolean`	`getOutputVarIsInited()` Gets the current output variable initialization status.
`String`	`getOutputVarName()` Gets the current output variable name.
`void`	`increaseIndent()` Increases the current indent.
`void`	`increaseIndentTwice()` Increases the current indent twice.
`abstract void`	`initOutputVarIfNecessary()` Appends a full line/statement for initializing the current output variable.
`void`	`popOutputVar()` Pops off the current output variable.
`void`	`pushOutputVar(String outputVarName)` Pushes on a new current output variable.
`void`	`setOutputVarInited()` Tells this CodeBuilder that the current output variable has already been initialized.

- Constructor Detail
  - CodeBuilder
```
public CodeBuilder()
```
    Constructs a new instance. At the start, the code is empty and the indent is 0 spaces.
- Method Detail
  - increaseIndent
```
public void increaseIndent()
```
    Increases the current indent.
  - increaseIndentTwice
```
public void increaseIndentTwice()
```
    Increases the current indent twice.
  - decreaseIndent
```
public void decreaseIndent()
```
    Decreases the current indent.
  - decreaseIndentTwice
```
public void decreaseIndentTwice()
```
    Decreases the current indent twice.
  - pushOutputVar
```
public void pushOutputVar(String outputVarName)
```
    Pushes on a new current output variable.
    
    Parameters:
    outputVarName - The new output variable name.
  - popOutputVar
```
public void popOutputVar()
```
    Pops off the current output variable. The previous output variable again becomes the current.
  - setOutputVarInited
```
public void setOutputVarInited()
```
    Tells this CodeBuilder that the current output variable has already been initialized. This causes initOutputVarIfNecessary and addToOutputVar to not add initialization code even on the first use of the variable.
  - getOutputVarName
```
public String getOutputVarName()
```
    Gets the current output variable name.
    
    Returns:
    The current output variable name.
  - append
```
public CodeBuilder<E> append(String... codeFragments)
```
    Appends one or more strings to the generated code.
    
    Parameters:
    codeFragments - The code string(s) to append.
    
    Returns:
    This CodeBuilder (for stringing together operations).
  - appendLine
```
public CodeBuilder<E> appendLine(String... codeFragments)
```
    Appends the current indent, then the given strings, then a newline.
    
    Parameters:
    codeFragments - The code string(s) to append.
    
    Returns:
    This CodeBuilder (for stringing together operations).
  - appendLineStart
```
public CodeBuilder<E> appendLineStart(String... codeFragments)
```
    Appends the current indent, then the given strings.
    
    Parameters:
    codeFragments - The code string(s) to append.
    
    Returns:
    This CodeBuilder (for stringing together operations).
  - appendLineEnd
```
public CodeBuilder<E> appendLineEnd(String... codeFragments)
```
    Appends the given strings, then a newline.
    
    Parameters:
    codeFragments - The code string(s) to append.
    
    Returns:
    This CodeBuilder (for stringing together operations).
  - appendOutputVarName
```
public CodeBuilder<E> appendOutputVarName()
```
    Appends the name of the current output variable.
    
    Returns:
    This CodeBuilder (for stringing together operations).
  - getCode
```
public String getCode()
```
    Returns:
    The generated code.
  - initOutputVarIfNecessary
```
public abstract void initOutputVarIfNecessary()
```
    Appends a full line/statement for initializing the current output variable.
  - addToOutputVar
```
public abstract void addToOutputVar(List<? extends E> targetExprs)
```
    Appends a line/statement with the concatenation of the given target expressions saved to the current output variable.
    
    Parameters:
    targetExprs - One or more target expressions to compute output.
  - getOutputVarIsInited
```
protected boolean getOutputVarIsInited()
```
    Gets the current output variable initialization status.
    
    Returns:
    The current output variable initialization status.
