TableName (Apache Derby V10.14 Internals)

java.lang.Object
- org.apache.derby.impl.sql.compile.QueryTreeNode
- - org.apache.derby.impl.sql.compile.TableName

All Implemented Interfaces:

Visitable
```
public class TableName
extends QueryTreeNode
```
A TableName represents a qualified name, externally represented as a schema name and an object name separated by a dot. This class is misnamed: it is used to represent the names of other object types in addition to tables.

    Parameters:
    
    schemaName - The name of the schema being referenced
    
    tableName - The name of the table or other object being referenced
    
    cm - The context manager

          ContextManager cm)
```
    Constructor for when we have both the table and schema names.
    
    Parameters:
    
    schemaName - The name of the schema being referenced
    
    tableName - The name of the table or other object being referenced
    
    tokBeginOffset - begin position of token for the table name identifier from parser. pass in -1 if unknown
    
    tokEndOffset - end position of token for the table name identifier from parser. pass in -1 if unknown
    
    cm - The context manager
- Method Detail
  - getTableName
```
public java.lang.String getTableName()
```
    Get the table name (without the schema name).
    
    Returns:
    
    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
```
public java.lang.String getSchemaName()
```
    Get the schema name.
    
    Returns:
    
    Schema name as a String
  - setSchemaName
```
void setSchemaName(java.lang.String schemaName)
```
    Set the schema name.
    
    Parameters:
    
    schemaName - Schema name as a String
  - getFullTableName
```
java.lang.String getFullTableName()
```
    Get the full table name (with the schema name, if explicitly specified).
    
    Returns:
    
    Full table name as a String
  - getFullSQLName
```
public java.lang.String getFullSQLName()
```
    Get the full SQL name of this object, properly quoted and escaped.
  - toString
```
public java.lang.String toString()
```
    Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.
    
    Overrides:
    
    toString in class QueryTreeNode
    
    Returns:
    
    This object as a String
  - equals
```
boolean equals(TableName otherTableName)
```
    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
```
boolean equals(java.lang.String otherSchemaName,
               java.lang.String otherTableName)
```
    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
```
public TableName cloneMe()
```
    Clone this TableName
  - bind
```
void bind()
   throws StandardException
```
    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.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    hash code for this table name
  - equals
```
public boolean equals(java.lang.Object other)
```
    Compares two TableNames. Needed for hashing logic to work.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    other - other tableName
