# Class SourceAwareCustomizer

java.lang.Object
org.codehaus.groovy.control.customizers.CompilationCustomizer
org.codehaus.groovy.control.customizers.DelegatingCustomizer
org.codehaus.groovy.control.customizers.SourceAwareCustomizer

All Implemented Interfaces:
  `CompilationUnitAware`, `CompilationUnit.IPrimaryClassNodeOperation`

public class SourceAwareCustomizer extends DelegatingCustomizer
A base class for customizers which only have to be applied on specific source units. This is for example useful if you want a customizer to be applied only for files matching some extensions.

For convenience, this class implements several methods that you may extend to customize the behaviour of this utility. For example, if you want to apply a customizer only for classes matching the '.foo' file extension, then you only have to override the `acceptExtension(String)` method:

    return "foo".equals(extension)

Since:
  2.1.0

  - ### SourceAwareCustomizer

    public SourceAwareCustomizer(CompilationCustomizer delegate)
    Creates a source-aware wrapper around another compilation customizer.
    Parameters:
      `delegate` - the customizer to invoke when the source matches

- ## Method Details

  - ### call

    public void call(SourceUnit source, GeneratorContext context, ClassNode classNode) throws CompilationFailedException
    Invokes the delegate only when the source and class validators accept the current input.
    Specified by:
      `call` in interface `CompilationUnit.IPrimaryClassNodeOperation`
    Overrides:
      `call` in class `DelegatingCustomizer`
    Parameters:
      `source` - the source unit being customized
      `context` - the current generator context
      `classNode` - the class node being customized
    Throws:
      `CompilationFailedException` - if the delegate fails

  - ### setBaseNameValidator

    public void setBaseNameValidator(Closure<Boolean> baseNameValidator)
    Sets the predicate used to validate source base names.
    Parameters:
      `baseNameValidator` - the validator to use

  - ### setExtensionValidator

    public void setExtensionValidator(Closure<Boolean> extensionValidator)
    Sets the predicate used to validate source file extensions.
    Parameters:
      `extensionValidator` - the validator to use

  - ### setSourceUnitValidator

    public void setSourceUnitValidator(Closure<Boolean> sourceUnitValidator)
