TraitCodegenWriter (Smithy API 1.50.0)

java.lang.Object
- software.amazon.smithy.utils.AbstractCodeWriter<W>
- - software.amazon.smithy.codegen.core.SymbolWriter<TraitCodegenWriter,software.amazon.smithy.traitcodegen.writer.TraitCodegenImportContainer>
  - - software.amazon.smithy.traitcodegen.writer.TraitCodegenWriter

All Implemented Interfaces:

SymbolDependencyContainer
```
public class TraitCodegenWriter
extends SymbolWriter<TraitCodegenWriter,software.amazon.smithy.traitcodegen.writer.TraitCodegenImportContainer>
```
Writes Java code for trait definitions.
This writer supports two custom formatters, a Java type formatter '$T' and a Base type formatter '$B'.

TraitCodegenWriter.JavaTypeFormatter|'T'

This formatter handles the formatting of Java types and also ensures that parameterized types (such as List<String> are written correctly.

TraitCodegenWriter.BaseTypeFormatter|'B'

This formatter allows you to use the base type for a trait. For example a String Trait may have a base type of ShapeId. To write this base type, use the $B formatter and provide the trait symbol. Note that if no base type is found (i.e. type is not a trait) then this formatter behaves exactly the same as the TraitCodegenWriter.JavaTypeFormatter.

TraitCodegenWriter.CapitalizingFormatter|'U'

This formatter will capitalize the first letter of any string literal it is used to format.

- Method Detail
  - writeDocString
```
public void writeDocString(java.lang.String contents)
```
    Writes the provided text in the format of a Java doc string.
    
    Parameters:
    
    contents - text to format as a doc string.
  - toString
```
public java.lang.String toString()
```
    Description copied from class: AbstractCodeWriter
    
    Gets the contents of the generated code.
    The result will have an appended newline if the AbstractCodeWriter is configured to always append a newline. A newline is only appended in these cases if the result does not already end with a newline.
    
    Overrides:
    
    toString in class AbstractCodeWriter<TraitCodegenWriter>
    
    Returns:
    
    Returns the generated code.
