public boolean equals(Object otherTableKey) Overrides java.lang.Object.equals. 2 TableKeys are equal if their both their schemaIds and tableNames are equal. Parameters otherTableKey:Object The other TableKey, as Object. Returns:boolean boolean Whether or not the 2 TableKey are equal.

equals

public boolean equals(Object otherTableKey)

2 TableKeys are equal if their both their schemaIds and tableNames are equal.

boolean Whether or not the 2 TableKey are equal.

getSchemaId	back to summary
pack-priv UUID getSchemaId() Get the schema id. Returns:UUID Schema id as a String

getSchemaId

pack-priv UUID getSchemaId()

Get the schema id.

hashCode back to summary

hashCode	back to summary
public int hashCode() Overrides java.lang.Object.hashCode. Doc from java.lang.Object.hashCode. Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by `java.util.HashMap`. The general contract of `hashCode` is: Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. If two objects are equal according to the `equals` method, then calling the `hashCode` method on each of the two objects must produce the same integer result. It is not required that if two objects are unequal according to the `equals` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables. Returns:int a hash code value for this object
