antlr.BaseAST
antlr.CommonAST
com.sun.jdo.spi.persistence.support.ejb.ejbqlc.EJBQLAST
All Implemented Interfaces:
antlr.collections.AST, Serializable, Cloneable
public class EJBQLAST extends antlr.CommonAST implements Cloneable
An instance of this class represents a node of the intermediate representation (AST) used by the query compiler. It stores per node:
  • token type info
  • token text
  • line info
  • column info
  • type info the semantic analysis calculates the type of an expression and adds this info to each node.

    • 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, String text, Object 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:

    • setTypeInfo

      public void setTypeInfo(Object typeInfo)

    • getTypeInfo

      public Object getTypeInfo()

    • toString

      public String toString()
      Returns a string representation of this EJBQLAST w/o child ast 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.

    • clone

      protected Object clone() throws CloneNotSupportedException
      Creates and returns a copy of this object. The returned EJBQLAST 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 Object
      Returns:
      a clone of this instance.
      Throws:
      CloneNotSupportedException
