ArrayLookup
public class ArrayLookup extends Expression (Code)
	An ArrayLookup can access indexed properties on objects. A Bean Introspector can be used to get the available indexed properties from an object, however, the only ones supported by Tea are unnamed. For this reason, the Introspector is not used. Any class with methods named "get" that return something and have a single parameter (the type of which is not limited to ints) will support an array lookup. Arrays, Collections and Strings are treated specially, and they all support array lookup on an int typed index. author: Brian S O'Neill version: 23 , 9/07/00 See Also: com.go.tea.util.BeanAnalyzer

Constructor Summary
public	ArrayLookup(SourceInfo info, Expression expr, Token lookupToken, Expression lookupIndex)

Method Summary
public Object	accept(NodeVisitor visitor)
public Object	clone()
public Expression	getExpression()
public Expression	getLookupIndex()
public Token	getLookupToken()
public Method	getReadMethod() Returns the method to invoke in order to perform the lookup.
public boolean	isExceptionPossible()
public void	setExpression(Expression expr)
public void	setLookupIndex(Expression lookupIndex)
public void	setReadMethod(Method m)

Constructor Detail

ArrayLookup
public ArrayLookup(SourceInfo info, Expression expr, Token lookupToken, Expression lookupIndex)(Code)

Method Detail

accept
public Object accept(NodeVisitor visitor)(Code)

clone
public Object clone()(Code)

getExpression
public Expression getExpression()(Code)

getLookupIndex
public Expression getLookupIndex()(Code)

getLookupToken
public Token getLookupToken()(Code)

getReadMethod
public Method getReadMethod()(Code)
	Returns the method to invoke in order to perform the lookup. This is filled in by the type checker. If the expression type is an array, the read method is null. A code generator must still be able to get elements from an array.

isExceptionPossible
public boolean isExceptionPossible()(Code)

setExpression
public void setExpression(Expression expr)(Code)

setLookupIndex
public void setLookupIndex(Expression lookupIndex)(Code)

setReadMethod
public void setReadMethod(Method m)(Code)
