Field Detail

UNDEFINED

@AlwaysNull
static final TypeVariableSource UNDEFINED

Indicates that a type variable source is undefined.

Method Detail

getTypeVariables

TypeList.Generic getTypeVariables()

Returns the type variables that are declared by this element.

Returns:

The type variables that are declared by this element.

getEnclosingSource

@MaybeNull
TypeVariableSource getEnclosingSource()

Returns the enclosing source of type variables that are valid in the scope of this type variable source.

Returns:

The enclosing source or null if no such source exists.

isInferrable

boolean isInferrable()

Returns true if type variables declared by this type variable source allow dynamic type inference.

Returns:

true if type variables declared by this type variable source allow dynamic type inference.

findVariable

@MaybeNull
TypeDescription.Generic findVariable(String symbol)

Finds a particular variable with the given name in the closes type variable source that is visible from this instance.

Parameters:

symbol - The symbolic name of the type variable.

Returns:

The type variable or null if it was not found.

findExpectedVariable

TypeDescription.Generic findExpectedVariable(String symbol)

Finds a particular variable with the given name in the closes type variable source that is visible from this instance. If the variable is not found, an exception is thrown.

Parameters:

symbol - The symbolic name of the type variable.

Returns:

The type variable.

accept

<T> T accept(TypeVariableSource.Visitor<T> visitor)

Applies a visitor on this type variable source.

Type Parameters:

T - The visitor's return type.

Parameters:

visitor - The visitor to apply.

Returns:

The visitor's return value.

isGenerified

boolean isGenerified()

Checks if this type variable source has a generic declaration. This means:

• A type declares type variables or is an inner class of a type with a generic declaration.
• A method declares at least one type variable.
• A type is a class that is declared within a method with a generic declaration.

Returns:

true if this type code element has a generic declaration.
