Field Detail

dtback to summary
public final Datatype dt

Datatype object that is used to test the equality.

nameback to summary
public final StringPair name

name of this datatype. The value of this field is not considered as significant. When two TypedStringExps share the same Datatype object, then they are unified even if they have different names.

serialVersionUIDback to summary
private static final long serialVersionUID

Hides com.sun.msv.grammar.Expression.serialVersionUID.

valueback to summary
public final Object value

This expression matches this value only.

Method Detail

calcEpsilonReducibilityback to summary
protected boolean calcEpsilonReducibility()

Implements abstract com.sun.msv.grammar.Expression.calcEpsilonReducibility.

Doc from com.sun.msv.grammar.Expression.calcEpsilonReducibility.

computes epsilon reducibility

calcHashCodeback to summary
protected final int calcHashCode()

Implements abstract com.sun.msv.grammar.Expression.calcHashCode.

Doc from com.sun.msv.grammar.Expression.calcHashCode.

Computes the hashCode again.

This method and the parameter to the constructor has to be the same. This method is used when the object is being read from the stream.

equalsback to summary
public boolean equals(Object o)

Implements abstract com.sun.msv.grammar.Expression.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
o:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.
