java.lang.Object

org.netbeans.spi.debugger.jpda.Evaluator.Expression<PreprocessedInfo>

Enclosing interface:

Evaluator<PreprocessedInfo>

public static final class Evaluator.Expression<PreprocessedInfo>
extends Object

Representation of an expression that is a subject of evaluation. String expressions are evaluated. But this class allows to attach a custom preprocessed structure to the expression, which can be used on subsequent evaluations of the same expression. Clients can, but does not have to, set a pre-processed object and during repeated evaluations of the same expression use that pre-processed object to speed up the evaluation. The preprocessed object should not be Evaluator.Context-sensitive.

public Expression(String expression)

Creates a new expression from the string representation.

Parameters:

expression - The string expression.

Method Detail

getExpression

public String getExpression()

Get the string representation of this expression.

Returns:

string expression

setPreprocessedObject

public void setPreprocessedObject(PreprocessedInfo preprocessed)

Set a pre-processed object of the string expression. A custom, client-specific object is expected, which represents the expression. This can be a syntax tree structure or whatever that speeds up repeated evaluations of the same expression.

Parameters:

preprocessed - object holding the information about pre-processed expression

getPreprocessedObject

public PreprocessedInfo getPreprocessedObject()

Get the pre-processed object of the string expression. The object set by Evaluator.Expression.setPreprocessedObject(java.lang.Object) is returned.

Returns:

the preprocessed object or null.
