TransposableNode

public TransposableNode(Object v)

Specifications:

public normal_behavior
assignable value;
ensures this.value == v;

equals

public boolean equals(nullable Object o)

Description copied from interface: JMLType

Test whether this object's value is equal to the given argument.

Specified by:

equals in interface NodeType

Overrides:
