Constructor Detail

DropRoleNode

public DropRoleNode()
Method Detail

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
