Field Detail

astjEnum

protected ASTJEnum astjEnum

Enum to convert to type

ast

protected org.eclipse.jdt.core.dom.AST ast

AST of the source and converted node

enumChildren

protected java.util.List<JNode> enumChildren

List of children of the enum

fieldInitializersMap

protected java.util.Map<java.lang.String,ASTJField> fieldInitializersMap

Constructor Detail

ASTNodeConverter.EnumToTypeConverter

public ASTNodeConverter.EnumToTypeConverter(ASTJEnum astjEnum)

Parameters:

astjEnum - to convert

Method Detail

convert

public ASTJType convert()

Converts enum to the class declaration.

Name, flags, comment, super interfaces of the class declaration are set from the enum.

All children of the enum are added to the class declaration. Enum constants are converted to public static final fields with initializer value created from arguments and body of enum constant.

Specified by:

convert in class ASTNodeConverter.Converter

Returns:

converted type, or null if conversion not possible

See Also:

setFieldInitializer(ASTJField, ASTJEnumConstant)

convertEnumConstToField

protected ASTJNode<?> convertEnumConstToField(ASTJEnumConstant enumConstant)

Converts enum constant to field.

Resulting field is public static final. The type of the field is the name of the enum. Comment of the field is copied from the enum constant. Initializer value is a call to the constructor of the enum (or converted type) with arguments taken from enum constant.

Parameters:

enumConstant - to convert

Returns:

converted field

See Also:

setFieldInitializer(ASTJField, ASTJEnumConstant)

setFieldInitializer

protected void setFieldInitializer(ASTJField field,
                                   ASTJEnumConstant enumConstant)

Sets field initializer based on arguments and body of enum constant.

Initializer string is in the form

 new Type ( ArgumentsList ) AnonymousClassDeclaration

where

• Type is the the type of the class
• ArgumentsList is the arguments of the enum constant with some arguments replaced by the names of static final fields. Arguments that match the initializer value of any public static final field are replaced by the name of that field.
• AnonymousClassDeclaration is the body of enum constant

Parameters:

field -

enumConstant -
