- Table name as a String
-
hasSchema
public boolean hasSchema()Return true if this instance was initialized with not null schemaName.- Returns:
- true if this instance was initialized with not null schemaName
-
getSchemaName

toString
Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.- Overrides:
toString
in classQueryTreeNode
- Returns:
- This object as a String
-
equals
2 TableNames are equal if their both their schemaNames and tableNames are equal, or if this node's full table name is null (which happens when a SELECT * is expanded). Also, only check table names if the schema name(s) are null.- Parameters:
otherTableName
- The other TableName.- Returns:
- boolean Whether or not the 2 TableNames are equal.
-
equals
2 TableNames are equal if their both their schemaNames and tableNames are equal, or if this node's full table name is null (which happens when a SELECT * is expanded). Also, only check table names if the schema name(s) are null.- Parameters:
otherSchemaName
- The other TableName.otherTableName
- The other TableName.- Returns:
- boolean Whether or not the 2 TableNames are equal.
-
cloneMe
Clone this TableName -
bind
Bind this TableName. This means filling in the schema name if it wasn't specified.- Throws:
StandardException
- Thrown on error
-
hashCode
public int hashCode()Returns a hash code for this tableName. This allows us to use TableNames as keys in hash lists. -
equals
Compares two TableNames. Needed for hashing logic to work.
