The full state field path expression, which is used to determine if it's an enum type.

Constructor Detail

StateFieldResolver

StateFieldResolver(Resolver parent,
                   java.lang.String path,
                   java.lang.String stateFieldPath)

Creates a new StateFieldResolver.

Parameters:

parent - The parent Resolver, which is never null

path - The state field path, which is the last path of the state field path expression

stateFieldPath - The full state field path expression, which is used to determine if it's an enum type

Method Detail

accept

public void accept(ResolverVisitor visitor)

Visits this Resolver by the given visitor.

Specified by:

accept in class Resolver

Parameters:

visitor - The visitor to visit this object

buildType

IType buildType()

Resolves the IType of the property handled by this Resolver.

Overrides:

buildType in class Resolver

Returns:

Either the IType that was resolved by this Resolver or the IType for IType.UNRESOLVABLE_TYPE if it could not be resolved

buildTypeDeclaration

ITypeDeclaration buildTypeDeclaration()

Resolves the ITypeDeclaration of the property handled by this Resolver.

Overrides:

buildTypeDeclaration in class AbstractPathResolver

Returns:

Either the ITypeDeclaration that was resolved by this Resolver or the ITypeDeclaration for IType.UNRESOLVABLE_TYPE if it could not be resolved

getEnumType

private IType getEnumType()

getStateFieldPath

public java.lang.String getStateFieldPath()

Returns

Returns:

isEnumType

public boolean isEnumType()

Determines whether the state field path expression is actually an enum type.

Returns:

true if the path represents the fully qualified enum type with the enum constant; false to indicate it's a real state field path expression

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
