Method Detail

init

public void init(Object invocation,
        Object correlationName,
        Object derivedRCL,
        Object tableProperties)
          throws StandardException

Description copied from class: QueryTreeNode

Initialize a query tree node.

Overrides:

init in class QueryTreeNode

Parameters:

invocation - The constructor or static method for the VTI

correlationName - The correlation name

derivedRCL - The derived column list

tableProperties - Properties list associated with the table

Throws:

StandardException - Thrown on error

init

public void init(Object invocation,
        Object correlationName,
        Object derivedRCL,
        Object tableProperties,
        Object exposedTableName)
          throws StandardException

Description copied from class: QueryTreeNode

Initialize a query tree node.

Overrides:

init in class QueryTreeNode

Parameters:

invocation - The constructor or static method for the VTI

correlationName - The correlation name

derivedRCL - The derived column list

tableProperties - Properties list associated with the table

exposedTableName - The table name (TableName class)

Throws:

StandardException - Thrown on error

copyFrom

public void copyFrom(QueryTreeNode node)
              throws StandardException

Fill this node with a deep copy of the given node.

Overrides:

copyFrom in class FromTable

Throws:

StandardException

toString

public 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 FromTable

Returns:

This object as a String

printSubNodes

public void printSubNodes(int depth)

Prints the sub-nodes of this object. See QueryTreeNode.java for how tree printing is supposed to work.

Overrides:

printSubNodes in class ResultSetNode

Parameters:

depth - The depth of this node in the tree

isConstructor

public boolean isConstructor()

Return true if this VTI is a constructor. Otherwise, it is a static method.

getMethodCall

public MethodCallNode getMethodCall()

Return the constructor or static method invoked from this node

getExposedName

public String getExposedName()

Get the exposed name for this table, which is the name that can be used to refer to it in the rest of the query.

Overrides:

getExposedName in class FromTable

Returns:

The exposed name for this table.

getExposedTableName

public TableName getExposedTableName()

Returns:

the table name used for matching with column references.

referencesTarget

public boolean referencesTarget(String name,
                       boolean baseTable)
                         throws StandardException

Search to see if a query references the specifed table name.

Parameters:

name - Table name (String) to search for.

baseTable - Whether or not name is for a base table

Returns:

true if found, else false

Throws:

StandardException - Thrown on error
