AbstractExprNode

protected AbstractExprNode(AssertionType assertionType)

Creates a node by setting abstract node type.

Parameters:

assertionType - The node's type

Method Detail

getAssertionType

public AssertionType getAssertionType()

Description copied from interface: ExprNode

Gets the assertion type of this node. Make it possible to use switch statements on the node type.

Specified by:

getAssertionType in interface ExprNode

Returns:

the node's type

See Also:

ExprNode.getAssertionType()

equals

public boolean equals(Object o)

Overrides:

equals in class Object

Returns:

true if both objects are equal

See Also:

Object.equals(Object)

hashCode

public int hashCode()

Overrides:

hashCode in class Object

Returns:

the instance's hash code

See Also:

Object.hashCode()

get

public Object get(Object key)

Description copied from interface: ExprNode

Gets an annotation on the tree by key.

Specified by:

get in interface ExprNode

Parameters:

key - the annotation key.

Returns:

the annotation value.

set

public void set(String key,
                Object value)

Description copied from interface: ExprNode

Sets a annotation key to a value.

Specified by:

set in interface ExprNode

Parameters:

key - the annotation key.

value - the annotation value.

See Also:

ExprNode.set(String, Object)

getAnnotations
