Field Summary

Fields

Modifier and Type	Field and Description
static int	ARRAY_ELEMENT A type path step that steps into the element type of an array type.
static int	INNER_TYPE A type path step that steps into the nested type of a class type.
static int	TYPE_ARGUMENT A type path step that steps into a type argument of a generic type.
static int	WILDCARD_BOUND A type path step that steps into the bound of a wildcard type.

Method Summary

Modifier and Type	Method and Description
static TypePath	fromString(java.lang.String typePath) Converts a type path in string form, in the format used by toString(), into a TypePath object.

Method Detail

getLength

public int getLength()

Returns the length of this path, i.e. its number of steps.

Returns:

the length of this path.

getStep

public int getStep(int index)

Returns the value of the given step of this path.

Parameters:

index - an index between 0 and getLength(), exclusive.

Returns:

one of ARRAY_ELEMENT, INNER_TYPE, WILDCARD_BOUND, or TYPE_ARGUMENT.

getStepArgument

public int getStepArgument(int index)

Returns the index of the type argument that the given step is stepping into. This method should only be used for steps whose value is TYPE_ARGUMENT.

Parameters:

index - an index between 0 and getLength(), exclusive.

Returns:

the index of the type argument that the given step is stepping into.

fromString

public static TypePath fromString(java.lang.String typePath)

Converts a type path in string form, in the format used by toString(), into a TypePath object.

Parameters:

typePath - a type path in string form, in the format used by toString(). May be null or empty.

Returns:

the corresponding TypePath object, or null if the path is empty.

toString

public java.lang.String toString()

Returns a string representation of this type path. ARRAY_ELEMENT steps are represented with '[', INNER_TYPE steps with '.', WILDCARD_BOUND steps with '*' and TYPE_ARGUMENT steps with their type argument index in decimal form followed by ';'.

Overrides:
