Field Detail

TYPE

public static final ErrorT TYPE

The canonical error type.

Constructor Detail

ErrorT

public ErrorT()

Create a new error type.

ErrorT

public ErrorT(Type template)

Create a new error type.

Parameters:

template - The type whose annotations to copy.

Method Detail

copy

public ErrorT copy()

Description copied from class: Type

Create a deep copy of this type. The resulting type is not sealed.

Specified by:

copy in class Type

Returns:

A deep copy of this type.

tag

public Type.Tag tag()

Description copied from class: Type

Get this type's tag. Invocations to this method are forwarded across wrapped types.

Specified by:

tag in class Type

Returns:

This type's tag.

See Also:

Type.wtag()

isError

public boolean isError()

Description copied from class: Type

Determine whether this type is an error.

Overrides:

isError in class Type

Returns:

true if this type is internal.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

write

public void write(java.lang.Appendable out)
           throws java.io.IOException

Description copied from class: Node

Write a human readable representation to the specified appendable. If this node supports generic traversal, the default implementation writes this node in algebraic term-format; otherwise, it writes the string returned by Object.toString().

Overrides:

write in class Node

Parameters:

out - The appendable.

Throws:

java.io.IOException - Signals an I/O error.

toString

public java.lang.String toString()

Description copied from class: Node

Return a human readable representation of this node. The default implementation creates a new string builder, writes this node to the builder, and then returns the corresponding string. Subclasses should typically override Node.write(Appendable).

Overrides:

toString in class Node

Returns:

A human readable representation.
