Class Schema  

java.lang.Object
  org.acs.damsel.srvr.schema.Schema

All Implemented Interfaces:

java.io.Serializable

---

public class Schema

extends java.lang.Object

implements java.io.Serializable

Title: Schema

Description: Schema holds a name for the schema (i.e., "Dublin Core", "Realia", etc) and a list of MetaDataTags that compose the Schema. Random access to tags is provided by isInSchema() and getTag(), sequential access by using the Iterator from tagsIterator(). Like MetaDataTags, Schemas are uniquely identified by name, even if their other properties are different.

Version:

1.0

Constructor Detail

Schema

public Schema()

Default constructor. Initializes the vector of schema tags.

Method Detail

addTag

public void addTag(MetaDataTag tag)
            throws SchemaException

Method adds a MetaDataTag to the schema. A SchemaException is thrown if a tag with the same name already exists in the Schema.

---

removeTag

public void removeTag(java.lang.String tagName)
               throws SchemaException

Method removes a MetaDataTag from the schema. A SchemaException is thrown if a tag with the same name does not exist in the Schema.

---

getTag

public MetaDataTag getTag(java.lang.String tagName)
                   throws SchemaException

Method returns the MetaDataTag with the given name. If no such MetaDataTag exists in the Schema, a SchemaException is thrown.

---

isInSchema

public boolean isInSchema(java.lang.String tagName)

Method returns true if the specified metadata tag is included in the current schema object, false otherwise.

---

isEmpty

public boolean isEmpty()

Method returns true if there are no tags in the schema, false otherwise

---

tagsIterator

public java.util.Iterator tagsIterator()

Method returns an iterator of all tags in the schema.

---

getName

public java.lang.String getName()

---

setName

public void setName(java.lang.String name)

---

equals

public boolean equals(java.lang.Object sch)

Description copied from class: java.lang.Object

Determine whether this Object is semantically equal to another Object.

There are some fairly strict requirements on this method which subclasses must follow:

• It must be transitive. If a.equals(b) and b.equals(c), then a.equals(c) must be true as well.
• It must be symmetric. a.equals(b) and b.equals(a) must have the same value.
• It must be reflexive. a.equals(a) must always be true.
• It must be consistent. Whichever value a.equals(b) returns on the first invocation must be the value returned on all later invocations.
• a.equals(null) must be false.
• It must be consistent with hashCode(). That is, a.equals(b) must imply a.hashCode() == b.hashCode(). The reverse is not true; two objects that are not equal may have the same hashcode, but that has the potential to harm hashing performance.

This is typically overridden to throw a java.lang.ClassCastException if the argument is not comparable to the class performing the comparison, but that is not a requirement. It is legal for a.equals(b) to be true even though a.getClass() != b.getClass(). Also, it is typical to never cause a java.lang.NullPointerException.

In general, the Collections API (java.util) use the equals method rather than the == operator to compare objects. However, java.util.IdentityHashMap is an exception to this rule, for its own good reasons.

The default implementation returns this == o.
