com.sun.jdo.spi.persistence.support.sqlstore.query.jqlc.JQLAST

All Implemented Interfaces:

antlr.collections.AST, Serializable

public class JQLAST
extends antlr.CommonAST

This class represents a node in the intermediate representation (AST) used by the query compiler. It provides - line info - column info - type info (object of class util.type.Type): the semantic analysis calculates the type of an expression and adds this info to each node. - RetrieveDesc info - value: this allows to add an arbitrary value to a node. This is used in compile time calulation of constant expression.

setRetrieveDesc

public void setRetrieveDesc(RetrieveDesc rd)

getRetrieveDesc

public RetrieveDesc getRetrieveDesc()

setValue

public void setValue(Object value)

getValue

public Object getValue()

toString

public String toString()

Returns a string representation of this JQLAST w/o child nodes.

Specified by:

toString in interface antlr.collections.AST

Overrides:

toString in class antlr.BaseAST

Returns:

a string representation of the object.

getTreeRepr

public String getTreeRepr(String title)

Returns a full string representation of this JQLAST. The returned string starts with the specified title string, followed by the string representation of this ast, followed by the string representation of the child ast nodes of this ast. The method dumps each ast node on a separate line. Child ast nodes are indented. The method calls toString to dump a single node w/o children.

Returns:

string representation of this ast including children.

getRetrieveDescRepr

public static String getRetrieveDescRepr(RetrieveDesc rd)

Returns a string representation of the spceified RetrieveDesc.
