Modifier and Type	Method and Description
protected <A extends Annotation> A	extractAnnotation(org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration<? extends org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration> declaration, Class<A> annotationType) Extracts an Annotation from class backing the declaration.
protected Optional<ExtensionParameter>	extractDeclaredParameter(org.mule.runtime.api.meta.model.declaration.fluent.ParameterDeclaration declaration) If the parameter was derived from a Java field or method argument, this method returns an ExtensionParameter which provides an abstraction over that field or argument

Method Detail

extractAnnotation

protected <A extends Annotation> A extractAnnotation(org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration<? extends org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration> declaration,
                                                     Class<A> annotationType)

Extracts an Annotation from class backing the declaration.

This method works in conjunction with extractImplementingTypeProperty(BaseDeclaration)

Type Parameters:

A - the annotation's generic type

Parameters:

declaration - a BaseDeclaration to be enriched

annotationType - the type of the annotation you want

Returns:

an Annotation or null if the annotation is not present or the declaration doesn't have a backing annotated type

extractImplementingTypeProperty

protected Optional<ImplementingTypeModelProperty> extractImplementingTypeProperty(org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration<? extends org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration> declaration)

Returns the annotated Class that was used to construct the declaration.

The annotated type is determined by querying the declaration for the ImplementingTypeModelProperty model property

Parameters:

declaration - a BaseDeclaration to be enriched

Returns:

a Class or null if the model doesn't have a ImplementingTypeModelProperty

extractImplementingType

protected Optional<Class> extractImplementingType(org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration<? extends org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration> declaration)

Parameters:

declaration - a BaseDeclaration

Returns:

The type from which the declaration was derived or Optional.empty() if it couldn't be determined or the declaration is synthetic

extractType

protected Optional<Type> extractType(org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration<? extends org.mule.runtime.api.meta.model.declaration.fluent.BaseDeclaration> declaration)

Parameters:

declaration - a BaseDeclaration

Returns:

The type from which the declaration was derived or Optional.empty() if it couldn't be determined or the declaration is synthetic

extractImplementingMethod

protected <T extends org.mule.runtime.api.meta.model.declaration.fluent.ExecutableComponentDeclaration> Optional<Method> extractImplementingMethod(org.mule.runtime.api.meta.model.declaration.fluent.ExecutableComponentDeclaration<T> declaration)

If the operation was derived from a Java method, this method extracts and returns it.

Parameters:

declaration - the operation's declaration

Returns:

an Optional Method

Since:

4.4.0

extractDeclaredParameter

protected Optional<ExtensionParameter> extractDeclaredParameter(org.mule.runtime.api.meta.model.declaration.fluent.ParameterDeclaration declaration)

If the parameter was derived from a Java field or method argument, this method returns an ExtensionParameter which provides an abstraction over that field or argument

Parameters:

declaration - the parameter's declaration

Returns:

an ExtensionParameter

Since:

4.4.0
