org.codehaus.groovy.grails.compiler.injection
[Java] Class AbstractGrailsArtefactTransformer

java.lang.Object
  org.codehaus.groovy.grails.compiler.injection.AbstractGrailsArtefactTransformer
All Implemented Interfaces:
java.lang.Comparable, GrailsArtefactClassInjector
@SuppressWarnings("rawtypes")
public abstract class AbstractGrailsArtefactTransformer
extends java.lang.Object

Abstract transformer that takes an implementation class and creates methods in a target ClassNode that delegate to that implementation class. Subclasses should override to provide the implementation class details

Method Detail

compareTo

public int compareTo(java.lang.Object o)
Used for ordering not equality. Note: this class has a natural ordering that is inconsistent with equals.
See Also:
java.lang.Comparable#compareTo(java.lang.Object)

getArtefactType

protected java.lang.String getArtefactType()

getArtefactTypes

public java.lang.String[] getArtefactTypes()

getInstanceImplementation

public java.lang.Class getInstanceImplementation()
The class that provides the implementation of all instance methods and properties
Returns:
A class whose methods contain a first argument of type object that is the instance

getStaticImplementation

public java.lang.Class getStaticImplementation()
The class that provides static methods
Returns:
A class or null if non is provided

isCandidateInstanceMethod

protected boolean isCandidateInstanceMethod(org.codehaus.groovy.ast.ClassNode classNode, org.codehaus.groovy.ast.MethodNode declaredMethod)

isStaticCandidateMethod

protected boolean isStaticCandidateMethod(@SuppressWarnings("unused") org.codehaus.groovy.ast.ClassNode classNode, org.codehaus.groovy.ast.MethodNode declaredMethod)

performInjection

public void performInjection(org.codehaus.groovy.control.SourceUnit source, org.codehaus.groovy.classgen.GeneratorContext context, org.codehaus.groovy.ast.ClassNode classNode)

performInjection

public void performInjection(org.codehaus.groovy.control.SourceUnit source, org.codehaus.groovy.ast.ClassNode classNode)

performInjectionInternal

@SuppressWarnings("unused")
protected void performInjectionInternal(java.lang.String apiInstanceProperty, org.codehaus.groovy.control.SourceUnit source, org.codehaus.groovy.ast.ClassNode classNode)
Subclasses can override to provide additional transformation
Parameters:
apiInstanceProperty
source - The source
classNode - The class node

populateAutowiredApiLookupMethod

protected org.codehaus.groovy.ast.MethodNode populateAutowiredApiLookupMethod(org.codehaus.groovy.ast.ClassNode implementationNode, @SuppressWarnings("unused") java.lang.String apiInstanceProperty, java.lang.String methodName, org.codehaus.groovy.ast.stmt.BlockStatement methodBody)

populateDefaultApiLookupMethod

protected org.codehaus.groovy.ast.MethodNode populateDefaultApiLookupMethod(org.codehaus.groovy.ast.ClassNode implementationNode, java.lang.String apiInstanceProperty, java.lang.String methodName, org.codehaus.groovy.ast.stmt.BlockStatement methodBody)

requiresAutowiring

protected boolean requiresAutowiring()
If the API requires autowiring then a
Autowired:
property will be added. If not a private field that instantiates the API will be crated. Defaults to true.
Returns:
Whether autowiring is required

requiresStaticLookupMethod

protected boolean requiresStaticLookupMethod()
Subclasses should override in the instance API requires a static lookup method instead of autowiring. Defaults to false.
Returns:
Whether a static lookup method is used for the instance API
