Method Details

isTypeVariable

public boolean isTypeVariable()

Description copied from interface: Argument

Whether this argument is a type variable used in generics.

Specified by:

isTypeVariable in interface Argument<T>

Returns:

True if it is a variable

getAnnotationMetadata

public AnnotationMetadata getAnnotationMetadata()

Description copied from interface: AnnotationMetadataProvider

Supplies the metadata. Defaults to AnnotationMetadata.EMPTY_METADATA.

Specified by:

getAnnotationMetadata in interface AnnotationMetadataProvider

Returns:

The AnnotationMetadata

getFirstTypeVariable

public Optional<Argument<?>> getFirstTypeVariable()

Specified by:

getFirstTypeVariable in interface TypeVariableResolver

Returns:

Return the first type parameter if it is present

getTypeParameters

public Argument[] getTypeParameters()

Specified by:

getTypeParameters in interface TypeVariableResolver

Returns:

The type parameters as an array

getTypeVariables

public Map<String,Argument<?>> getTypeVariables()

Specified by:

getTypeVariables in interface TypeVariableResolver

Returns:

Obtain a map of the type parameters for the argument

getType

@NonNull
public @NonNull Class<T> getType()

Specified by:

getType in interface TypeInformation<T>

Returns:

The type

isReactive

public boolean isReactive()

Specified by:

isReactive in interface TypeInformation<T>

Returns:

Is the return type reactive.

getName

@NonNull
public @NonNull String getName()

Specified by:

getName in interface Argument<T>

Specified by:

getName in interface Named

Returns:

The name of the argument

toString

public String toString()

Overrides:

toString in class Object

equalsType

public boolean equalsType(@Nullable
 @Nullable Argument<?> o)

Description copied from interface: Argument

Whether the types are equivalent. The regular Object.equals(Object) implementation includes the argument name within the comparison so this method offers a variation that just compares types.

Specified by:

equalsType in interface Argument<T>

Parameters:

o - The type type

Returns:

True if they are equal

equals

public boolean equals(Object o)

Overrides:

equals in class Object

typeHashCode

public int typeHashCode()

Description copied from interface: Argument

The hash code including only the types. The regular Object.hashCode() implementation includes the argument name within the comparison so this method offers a variation that just compares types.

Specified by:

typeHashCode in interface Argument<T>

Returns:

The type hash code

hashCode

public int hashCode()

Overrides:

hashCode in class Object

asArgument

@NonNull
public @NonNull Argument<T> asArgument()

Specified by:

asArgument in interface ArgumentCoercible<T>

Returns:

The argument
