Method Detail

init

public void init(java.lang.Object roleName)
          throws StandardException

Initializer for a DropRoleNode

Specified by:

init in interface Node

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
