Method Detail

acceptback to summary
public <T> T accept(TypeVariableSource.Visitor<T> visitor)

Applies a visitor on this type variable source.

Parameters
<T>
The visitor's return type.
visitor:TypeVariableSource.Visitor<T>

The visitor to apply.

Returns:T

The visitor's return value.

findExpectedVariableback to summary
public 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:String

The symbolic name of the type variable.

Returns:TypeDescription.Generic

The type variable.

findVariableback to summary
public 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:String

The symbolic name of the type variable.

Returns:TypeDescription.Generic

The type variable or null if it was not found.

  • A type is a class that is declared within a method with a generic declaration.
Returns:boolean

true if this type code element has a generic declaration.

isInferrableback to summary
public boolean isInferrable()

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