DropRoleNode
public DropRoleNode()
init
public void init(java.lang.Object roleName)
throws StandardException
- Initializer for a DropRoleNode
- Overrides:
init
in class DDLStatementNode
- Parameters:
roleName
- The name of the object being dropped
- Throws:
StandardException
- Thrown on error
bindStatement
public void bindStatement()
throws StandardException
- Description copied from class:
StatementNode
- Perform the binding operation statement. Binding consists of
permissions checking, view resolution, datatype resolution, and
creation of a dependency list (for determining whether a tree or
plan is still up to date).
This bindStatement() method does nothing.
Each StatementNode type that can appear
at the top of a tree can override this method with its
own bindStatement() method that does "something".
- Overrides:
bindStatement
in class StatementNode
- Throws:
StandardException
- Thrown on error
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 DDLStatementNode
- Returns:
- This object as a String
statementToString
public java.lang.String statementToString()
- Specified by:
statementToString
in class StatementNode
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
