tableName
private TableName tableName
exclusiveMode
private boolean exclusiveMode
conglomerateNumber
private long conglomerateNumber
lockTableDescriptor
private TableDescriptor lockTableDescriptor
LockTableNode
public LockTableNode()
init
public void init(java.lang.Object tableName,
java.lang.Object exclusiveMode)
- Initializer for LockTableNode
- Overrides:
init
in class QueryTreeNode
- Parameters:
tableName
- The table to lockexclusiveMode
- boolean, whether or not to get an exclusive lock.
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 StatementNode
- Returns:
- This object as a String
statementToString
public java.lang.String statementToString()
- Specified by:
statementToString
in class StatementNode
bindStatement
public void bindStatement()
throws StandardException
- Bind this LockTableNode. This means looking up the table,
verifying it exists and getting the heap conglomerate number.
- Overrides:
bindStatement
in class StatementNode
- Throws:
StandardException
- Thrown on error
referencesSessionSchema
public boolean referencesSessionSchema()
throws StandardException
- Return true if the node references SESSION schema tables (temporary or permanent)
- Overrides:
referencesSessionSchema
in class QueryTreeNode
- Returns:
- true if references SESSION schema tables, else false
- Throws:
StandardException
- Thrown on error
makeConstantAction
public ConstantAction makeConstantAction()
throws StandardException
- Create the Constant information that will drive the guts of Execution.
- Overrides:
makeConstantAction
in class QueryTreeNode
- Throws:
StandardException
- Thrown on failure
