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 mis-named: it is used to represent the names of other object types in addition to tables.

java.lang.String	getSchemaName()           Get the schema name.
java.lang.String	getTableName()           Get the table name (without the schema name).
int	getTokenBeginOffset()           Get the begin offset of the parser token for the table name Will only be set when the TableName was generated by the parser.
int	getTokenEndOffset()           Get the end offset of the parser token for the table name.
int	hashCode()           Returns a hashcode for this tableName.
boolean	hasSchema()           Return true if this instance was initialized with not null schemaName.
void	init(java.lang.Object schemaName, java.lang.Object tableName)           Initializer for when you have both the table and schema names.
void	init(java.lang.Object schemaName, java.lang.Object tableName, java.lang.Object tokBeginOffset, java.lang.Object tokEndOffset)           Initializer for when you have both the table and schema names.
void	setSchemaName(java.lang.String schemaName)           Set the schema name.
java.lang.String	toString()           Convert this object to a String.

Method Detail

init

public void init(java.lang.Object schemaName,
                 java.lang.Object tableName)

Initializer for when you have both the table and schema names.

Overrides:

init in class QueryTreeNode

---

init

public void init(java.lang.Object schemaName,
                 java.lang.Object tableName,
                 java.lang.Object tokBeginOffset,
                 java.lang.Object tokEndOffset)

Initializer for when you have both the table and schema names.

Overrides:

init in class QueryTreeNode

---

getTableName

public java.lang.String getTableName()

Get the table name (without the schema name).

---

hasSchema

public boolean hasSchema()

Return true if this instance was initialized with not null schemaName.

---

getSchemaName

public java.lang.String getSchemaName()

Get the schema name.

---

getTokenBeginOffset

public int getTokenBeginOffset()

Get the begin offset of the parser token for the table name Will only be set when the TableName was generated by the parser.

---

getTokenEndOffset

public int getTokenEndOffset()

Get the end offset of the parser token for the table name. Will only be set when the TableName was generated by the parser.

---

setSchemaName

public void setSchemaName(java.lang.String schemaName)

Set the schema name.

---

getFullTableName

public java.lang.String getFullTableName()

Get the full table name (with the schema name, if explicitly specified).

---

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

---

equals

public 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.

---

equals

public 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.

---

bind

public void bind(org.apache.derby.iapi.sql.dictionary.DataDictionary dataDictionary)
          throws org.apache.derby.iapi.error.StandardException

Bind this TableName. This means filling in the schema name if it wasn't specified.

---

hashCode

public int hashCode()

Returns a hashcode for this tableName. This allows us to use TableNames as keys in hash lists.

---

equals

public boolean equals(java.lang.Object other)

Compares two TableNames. Needed for hashing logic to work.
