Constructor Detail

LineMarker

public LineMarker(int line,
          java.lang.String file,
          int flags,
          Node node)

Create a new line marker.

Parameters:

line - The line number.

file - The file name.

flags - The flags.

node - The marked node.

Method Detail

hasTraversal

public boolean hasTraversal()

Description copied from class: Node

Determine whether this node supports generic traversal of its children. The default implementation returns false.

Overrides:

hasTraversal in class Node

Returns:

true if this node supports generic traversal of its children.

size

public int size()

Description copied from class: Node

Get the number of children. The default implementation signals an unsupported operation exception.

Overrides:

size in class Node

Returns:

The number of children.

get

public java.lang.Object get(int index)

Description copied from class: Node

Get the child at the specified index. The default implementation signals an unsupported operation exception.

Note that instance tests on the returned object may not behave as expected. Notably, any node may be wrapped in annotations. Furthermore, any string may be wrapped in a token (and, recursively, in annotations).

Overrides:

get in class Node

Parameters:

index - The index.

Returns:

The child at that positioin.

See Also:

Token.test(Object), Token.cast(Object), GNode.test(Object), GNode.cast(Object)

set

public java.lang.Object set(int index,
                   java.lang.Object value)

Description copied from class: Node

Set the child at the specified index to the specified value. The default implementation signals an unsupported operation exception.

Overrides:

set in class Node

Parameters:

index - The index.

value - The new value.

Returns:

The old value.

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
