Class JDOQLAST

java.lang.Object

antlr.BaseAST

antlr.CommonAST

org.apache.jdo.impl.jdoql.jdoqlc.JDOQLAST

All Implemented Interfaces:

antlr.collections.AST, java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

NodeImpl

public class JDOQLAST
extends antlr.CommonAST
implements java.lang.Cloneable

This class represents a node in the intermediate representation (AST) used by the query compiler. It provides - line info - column info - type info (JavaType instance): the semantic analysis calculates the type of an expression and adds this info to each node.

Method Detail

initialize

public void initialize(antlr.Token t)

Specified by:

initialize in interface antlr.collections.AST

Overrides:

initialize in class antlr.CommonAST

initialize

public void initialize(int type,
              java.lang.String text,
              JavaType typeInfo)

initialize

public void initialize(antlr.collections.AST _ast)

Specified by:

initialize in interface antlr.collections.AST

Overrides:

initialize in class antlr.CommonAST

setLine

public void setLine(int line)

getLine

public int getLine()

Specified by:

getLine in interface antlr.collections.AST

Overrides:

getLine in class antlr.BaseAST

setColumn

public void setColumn(int column)

getColumn

public int getColumn()

Specified by:

getColumn in interface antlr.collections.AST

Overrides:

getColumn in class antlr.BaseAST

setTypeInfo

public void setTypeInfo(JavaType typeInfo)

getTypeInfo

public JavaType getTypeInfo()

toString

public java.lang.String toString()

Returns a string representation of this JDOQLAST.

Specified by:

toString in interface antlr.collections.AST

Overrides:

toString in class antlr.BaseAST

Returns:

a string representation of the object.

treeToString

public java.lang.String treeToString()

Returns a string representation of this JDOQLAST including all child nodes.

Returns:

a string representation of this JDOQLAST including all child nodes.

clone

protected java.lang.Object clone()
                          throws java.lang.CloneNotSupportedException

Creates and returns a copy of this object. The returned JDOQLAST shares the same state as this object, meaning the fields type, text, line, column, and typeInfo have the same values. But it is not bound to any tree structure, thus the child is null and the sibling is null.

Overrides:

clone in class java.lang.Object

Returns:

a clone of this instance.

Throws:

java.lang.CloneNotSupportedException
