Method Detail

isStaticRef

public boolean isStaticRef()

Returns:

true if this is a static reference, false if this is an instance reference.

method

@Nullable
public JMethod method()

Returns:

The owning method. May be null if a constructor with method name was used.

type

@Nonnull
public AbstractJType type()

Returns:

The type owning the method. Never null .

var

@Nullable
public JVar var()

Returns:

The variable for the instance reference. May be null if this is a static reference.

methodName

@Nonnull
public String methodName()

Returns:

The name of the referenced method. Never null.

generate
