MSV Core 2022.7 · com.sun.msv.grammar.OtherExp

Base class for application-specific AGM annotation.

This primitive has no meaning to MSV. For example, the following expression

Expression exp = new OtherExp( pool.createSequence(a,b) );

is treated as if MSV sees the following, OtherExp-less expression:

Expression exp = pool.createSequence(a,b);

By using this "transparency", application can implement derived classes of OtherExp and add application-specific information to AGM.

For example, you can implement AnnotationInfoExp class that derives OtherExp and introduces "documentation" field. Then you'll write a customized XMLSchemaReader that parses <annotation> tag and mix AnnotationInfoExp into an AGM. Your application can then examine it and do some useful things.

Those application-specific information added through OtherExp are completely ignored by MSV. So the annotated AGM can still be used just like anormal AGM.

equals back to summary

equals	back 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.

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.
